Many thanks. Been on the phone to Aquarium gardens today, very very helpful company, decided to buy a new reg from them as mines been sitting around collecting dust and obviously getting damaged. New tank so I treated myself to a new reg to go with it :)

I've just dug out my co2 regulator and the plastic is missing from the front of one of the gauges. Will this still be OK to use? I'm presuming the CO2 doesn't reach the front of the gauge hence will be totally fine, just wanted to check first. thanks

Sent them an email last week (Dec 2020) asking if they still refill, and mentioned my fire extinguisher is over 10 years old, here is their reply

Just ordered the EF-2 : and a box of Bio balls :)

Hmm thanks :) I have a 180 lt tank and already have two 2217 filters on it (well ones a 2317). I'm replacing my Pro3 which I've given up on after numerous problems, I was running with just the pro 3, but since deciding to get rid of it, have purchased two 2217 filters to replace it and give me...

I'm thinking about replacing my up atomizer, not because I've had a problem with it, more because my new filter has 12/16 pipe and my up atomizer 16/22. Will do some tests first to see what the output is like using the 16/22 up atomiser and 16/22 spraybar (zeus gave me good advice in another...

I upped the bubble count a bit, hard to count in a second now. Things are a lot better, bubbles getting to the bottom of the tank, drop checker showing a drop from 7.5 before CO2 to 6.5 two hrs after CO2 went on. Also checked at 4 hrs and it had gone down to 6.4 Fish seem happy so don't think...

Zeus said on one of my threads that he uses https://www.amazon.co.uk/Semlos-Resolution-Calibration-0-00-14-00-Measurement/dp/B01C5OOF6I/ref=sr_1_3?ie=UTF8&qid=1507150456&sr=8-3&keywords=pH+pen That has a lot of good reviews, it also has about 36 reviews saying it's rubbish or inaccurate. I'm...

Thanks. I might get one of the pens. Today I took 4 test tubes, midday, 2pm, 4pm and 6pm (CO2 comes on at 1pm to 7pm) midday and 2pm were the same colour blue. I turned my co2 up slightly, 4pm and 6pm were getting towards green, very obviously more green than the first two. Maybe I need more...

Hi, I have a API multi test kit that's 7 years old, I also have an additional PH test kit that's about 5 years old. I have 4dkh solution. I had my CO2 on from 1pm until 7pm. I initially had my drop checker on the side of the tank, using 4dkh and a few drops from my 5 year old kit. It stayed...

I'm talking rubbish as usual :) While bubbles are still coming out, it's dropped from 60 to just under 30 bar, I squeeze the handle and it's back to 60, so all is working fine :)

A friend had a leather hole punch, that made a perfect size hole. Zero leaks :) The only very weird thing is it seems to work without squeezing the fire extinguisher handle. But the knob that pushes needle into FE turns fine and can turn bar to 0 or up to, well I set it at 3 (in line UP...

They look like they might do, glad its a packet of 50, already wasted 10 trying to make the hole bigger :) Drilling doesn't work, neither does heat. Using a scapel is impossible, ends up splitting it. Just tried a grinding dremel bit, that's made the hole bigger but not quite big enough...

Will get some from ebay, but want system up and running. might nip to Maplins and try these, can drill hole in middle bigger https://www.maplin.co.uk/p/silicon-washers-50-pack-a18gl

Just been to B&Q, nothing suitable there. Think I might have to get another reg :( all because I cant get a washer Had a response from theaquariumsolution ------------------------------------ Im afraid the washer isn’t something we would stock as a spare, it maybe worth trying a shop that...

Thanks all. I've hunted back and realised it was a D-D kit from aquariumsolutions I got cheap from my LFS, so I've emailed them, will see if they respond (just found an old thread on here with someone asking same thing, they emailed them and never got a response) Attached pics if anyone's...

A bit late, but I just found this site while looking for something else https://marine-world.co.uk/collections/spare-parts/co2-regulators

No, hard to explain, the washer needs to be a bit wider than the thread as it sits in a wider gap past the thread, hence fibre washer is either too small or breaks when getting it in. Will see if any of the things Stuart linked to dies the trick

Thanks, I have a box of assorted fibre washers, I'll see if one of those does the trick

Hi all. I stupidly took off my thread adapter today and the washer in the reg is ruined. It's a bowl shaped washer if that makes any sense. 12 mm edge to edge with a 6mm hole in the middle. Could I use an o-ring or a load of ptfe? the reg has MIGNON on the front and K1 N 081819 110 BAR RH...

Just had my 2kg refilled by Flame Skill in Great Yarmouth. £4. (Price list on wall for fishtank and paintball refills of various sizes)

FlameSkill in Gt Yarmouth refills my 2KG FE for just £3.60, been that price for the past few refills, even has that price listed on their wall in their office.

Many thanks.

Been using a FE for quite a while now, every time I refill it, I replace the fibre washer with a new one (all from the same batch). The previous refill, it was on the tank for about a month, when I heard a hissing sound, and had to tighten the main regulator nut onto the FE. I thought it was...

My local fire extinguisher company sold me a new/refurbished 2kg fire extinguisher minus the horn specifically for use in my aquarium. The one I took in was too old to refill without being pressure tested and while they were happy to do so, I needed it urgently hence they sold me a...

Many many thanks everyone Think I'm finally there at last :)

I THINK everything is now fine. Most of the fish are swimming happily all over the tank, 3 however have spent the last hour or so at the top towards the back corner (triangle tank), but whether that's a fluke or they think there's too much CO2, I'm not 100% sure. Have taken PH readings...

Thanks, just done final check at 10pm, it's still 6.4 but if I hold the test tube up against the one I did an hour ago, you can see it's slightly more green than 1 hr ago. Will keep a close eye on it tomorrow

Sorry, had to rush out as I typed last post, so typed it very quickly. As it's a corner tank, it's very deep. I've got a coralia pump in the corner pointing slightly down as per advice on this forum (similar to Ians lounge tank viewtopic.php?f=35&t=15058&hilit=Ian%E2%80%99s+Lounge+tank , in...

It's finally starting to change, it's still not what I'd call lime green though. Been experimenting with flow in the past couple of days, will put the bar back straight

Yep pressurised, 8 bar 1 side, 2 bar going into the atomizer

After another hr (8pm) ph is exactly 6.6

Have it on the outlet. If you see this pic, the right hand side is looking at it as per my filter pic in my original post, the left hand side is looking at it from the other side and you can see the up arrow is on the right hand side, which is the left hand side when it's round the other way,

Hi guys. Have replaced my home made reactor with an up atomizer but still seem to be struggling to get a decent amount of CO2 into my tank. I took a PH reading at just before 2pm before CO2 was on. it was 7.2 After 2 hrs with about 3 bubbles a second I took another PH reading, this time it...

Hmm, got my recon one from a professional fire systems company complete with receipt saying it was reconditioned and was told by them that it's fine for 10 years and just bring it back whenever it needed refilling. Anyway, thanks Alastair, found a load of fibre washers, one fitted perfectly and...

Hi all Today I went to get my fire extinguisher refilled and as it was 12 years old, they wouldn't do it. Long story short, I brought a reconditioned replacement. As far as I can remember, there was no washer between my D-D thread converter and the fire extinguisher. No matter how tight I...

Many thanks Tom

Hi all. Have taken the plunge and decided to replace my home made reactor with the up atomizer. Does it matter where I position it on the outlet pipe? For instance, can I position it a few inches after the pipe leaves the filter, and have it simply dangling (well dangling is the wrong word...

I did it your way (although I have a cheaper circulation pump which faces towards the glass, pushing the water round it, rather than down). Now when I drop fish flakes in, I can see them going the entire way around the tank. Many thanks

Many thanks It all appears to have gone superbly, cleaned the filter, bled the air out, no problems at all. Also changed disposable bottle for fire extinguisher, took about 3 mins to do (plus checking for leaks, there weren't any), thought it would be way more difficult. Finally I put in a...

That should be Juwel 190 not 170

Ah, that's what I forgot with my test, an o-ring (hides in the corner in embarrassment). Have done the real thing tonight, looks like I've done it fine, too late now to test, will put back on in the morning. Noticed the hozelock connectors don't make a very tight fit over normal air/co2...

Thanks. I have a Juwel 170

Did you work out an optimum position please? I am going through exactly the same thing this weekend. I've just ordered a circulation pump, problem I'm having with just the spraybar (same position as yours) is that the right hand half of the tank seems to be doing fine, but the left hand isn't...

Just had a play, think it's going to be perfect. Glad there's a few in the packet, tried fixing one to a spare piece of pipe, your instructions work fine. Only thing is, they're hard to turn, needing a spanner, it's very hard to judge when they're in fully. Tighten slightly too much and they...

Thanks Bob No the spray bar is only around 12". I think I'll get a full length spray bar and also a small in size powerhead/circulation pump. With the corner tank being so deep and the tanks shape, I'm not 100% convinced that a spray bar alone will achieve 100% circulation. Many thanks for...

Many many many thanks, will look at getting the hozelock bits tomorrow. Is it just a powerhead I need for better flow around the tank please? Don't really want a filter. What sort of flow should I be looking at for 170lt corner tank please? (already have my Eheim pro3 2073 going thorough...

Hi all, title not making it clear at all. I built a home made reactor a couple of months ago that's connected to the output of my external filter. It seems to be working reasonably well. I have 2 problems, both I THINK I have the answer to, but am not sure what I need. 1) The first problem...

Hi Are you all talking about the up atomiser as shown in the pic in this thread please? viewtopic.php?f=21&t=15815&start=20 Was just about to buy one, might go a different route if foxfish's experience is a common one. Thanks

Just to update. Everything seems to be going extremely well. For the first time in around 15 years, my plants are actually growing and not dying. Today I need to trim them for the first time ever as some have reached the top of the tank :D Thanks for all the advice

Thanks Colin. Yep it's working fine, a nice lime green. Was exactly as you described, (yellowy orange then turned blue). Thanks

Thanks all. Yep what you say makes sense Colin, however for someone new to CO2, it makes sense for me to have some sort of general indication as to CO2 getting into the tank and how well it's distributed (will be moving DC around every day to monitor different areas once I get it stabilised...

Thanks, cant believe I missed that from the instructions :) On a separate note, last night, after altering my electronic timer, for some reason it didn't turn off at all. I came down today to find all the fish at the top of the tank, thankfully all alive. i've turned the CO2 off and opened the...

I've ordered the glass drop checker and the 4dkh solution that was dispatched first class today from the sponsors. Will get hold of another check valve. Very odd, I watched when the co2 came on and the bubble counter was correctly 2/3rds full, but as soon as it came on the counter filled up...

Thanks all. Since putting the filter flow lever at 3/4 and giving it another couple of hours, the PH has dropped to between 6.4 and 6.6 on my chart. Lights and CO2 go off in 10 mins, so will see what happens tomorrow Note, have just read CO2 should go on and off an hour before the lights do...

Thanks all, will order the 4dkh and a glass drop checker from sponsors tomorrow (my one only has a tiny slit to get whatever it measures from the tank as opposed the glass ones that have a large open area). A bit confused about the pressure as when the CO2 is on, the bubble counter remains...

Yep, a few drops of the supplied solution topped up with tank water.

Not sure, I'm using this kit http://www.aquaessentials.co.uk/tmc-aqu ... -3813.html Wondering whether I should get one of the funny shaped glass ones instead? Thanks Joe

Just done a couple of PH readings using my normal PH testing kit and my high range PH kit. The high range one shows at 7.4 (lowest it goes) Normal one shows 7.0 Was about to say why the difference but using my brains, I presume as the normal one goes to 7.6 but shows 7.0 that is correct...

Just to add a bit if humour, my wife now agrees it's blue too. She was looking at the green sucker that holds it to the glass rather than the liquid in the drop checker :)

Hi all, me yet again. Last night I finally got my reg leak free and everything set up and working, using my home made reactor as per my thread viewtopic.php?f=20&t=15107 I've got it set up as follows. Regulator output into one way valve. One way valve into bubble counter. Bubble counter into...

Thanks both. Didn't realise how much tape I would need, about 20 times around the threads fixed it :)

Hi all My local FS had a saltwater D-D on sale reduced from £131 to £70, think it was old stock they were getting rid of. Brand new. D-D's faq said the only difference was it also came with a high pressure gauge and no diffuser. Not a problem, I've built a reactor. It was on display on the...
