    expired co2 ok to use ?

    I've got over 30 empties, hopefully one day i'll find some time and a reasonable re-fill station! If anyone is interest and local I have a lot of full 2kgs which you can have for a tenner each. I've had to give up posting them after a few courier drivers got a shock LOL

    Finding s leak??

    Providing you don't have a solanoid attached you should be able to submerse the hole lot under water and this will show you any leaks (when running), good quality regulators should be fine, some of the cheaper regs may not be suitable. If you're uncomfortable doing that then I'd suggest using a...

    red sea drop checker question

    Good stuff, if you have a read though this article it'll help http://www.ukaps.org/drop-checker.htm

    red sea drop checker question

    It's hard to say i'm afraid. Did you just get one bottle of blue solution or a number of small vials? Some companies, like Dennerle for instance sell the DC with a ready mixed solution in plastic viles.... If it's just one bottle then using a few drops with standard 4dkh water is fine. Cheers

    TMC Glass non return valve problem

    I'd get rid of the non-return valve and buy a steel one from Aqua Essentials or similar, they are really good. http://www.aquaessentials.co.uk/ae-desi ... -1607.html

    Carbonised Water?

    BTW, I dosed it daily.

    Carbonised Water?

    Just try it mate, it's not going to hurt and you'll be able to give everyone the answer that no-one seems to know....

    Carbonised Water?

    Sorry, fizzy water. Of corse Excel and EC work too.
  9. Dan Crawford

    Carbonised Water?

    It definitely works. Dose it at 1ml per 10L and see how it goes.

    hagen nutrafin system weird jelly

    You often find that with silicone hose I don't think it's detrimental but I'd swop it for CO2 hose from AE.

    PTFE tape

    A wealth of information there fellas, nice work. Maybe we should somehow link it to Sam's Thread about setting up a Fire Extinguisher CO2 System.
  13. Dan Crawford

    PTFE tape

    Any ideas as to why not Stu?
  14. Dan Crawford

    PTFE tape

    I've done setups with and without PTFE, I do think CO2 lasts longer with PTFE on every seal. In my view it stands to reason, be it to "correct" stuff or not, it creates a better seal, doesn't it? I'm like Chris in that I have no formal training, just seems like common sense to me.

    Normal to lose pressure overnight?

    That's interesting, is it hard?
  18. Dan Crawford

    Normal to lose pressure overnight?

    To my knowledge, normal airline or silicone tubing allows CO2 to pass through the walls of the tube. When the solenoid is on you're trying to "hold" pressure within the tube and airline tubing isn't designed to do and can't do it. CO2 tubing from someone like AE will probably work better. I...

    Suitable CO2 Cylinder?

    Well if I were you i'd go with fire extinguishers, by far the most economical way to do it.... viewtopic.php?f=34&t=266
  20. Dan Crawford

    Suitable CO2 Cylinder?

    It really depends on what regulator you have, do you know if it fits or not? If it does then it could be a good buy, i've not bought welding CO2 before but some people do use it.

    Optimum Co2/Power head/Inlet/Outlet Equipment Placement?

    That all looks ok to me pal although i might have moved the diffuser to directly under the filter inlet.
  25. Dan Crawford

    Rhinox 5000

    That sounds fair Sam, my only observation when using an undersized diffuser is that the bubbles that are emitted from the ceramic disc seem to be bigger and in theory less likely to dissolve?

    Id say it'll do a great job :D

    I'm currently testing one at the mo and it's well cool! I'm running it on my 160l and it's still going strong after 2 weeks but obviously i can't tell you anymore till it's ran out completely. You can of corse go the fire extinguisher route for the same sort of cost.... here are some photos...

    Spio Diffuser

    No you don't have to fill it with water, generally they just end up with water in them anyway but you don't NEED water in there. They are pretty good diffusers.

    Securing a FE

    That looks like a great piece of kit, i might get one myself! Having a lock on the door will really help if it's possible, it could prevent all manner of potential disasters.

    splitter

    I've used a splitter before to good effect. It was one of the ones from TGM with a little "regulator" on it. It took some doing to get it right but once it was set it was great.

    A cheaper liquid source of carbon by AE Design Aqua Carbon

    I don't think George will mind me saying this but he dosed EasyCarbo as a CO2 alternative exclusively on a fast growing 60cm and for the first few months it seemed fine but i think after that it seemed to be seriously desperate for CO2 and the tank suffered. I think it can be an alternative in a...

    pressurized co2 causing NITRITE?

    How long was the filter off for when you rescaped? If it's over a few hours then most of your bacteria would have died of and you need to repopulate it. Adding some ammonia in a brand new tank would speed things up a bit but they will almost always cycle since there is always some ammonia in...

    How long CO2 canister should last, bps based?

    co2 inline reactor.

    I had a smaller one of these and it just leaked like crazy, all over the place. I gave it to SteveUK to have a play with. It would make a lot of sense if it were meant to be inside the tank as the leaking wouldn't really matter. Good luck with it, i hope it's better than mine was!

    Glass Bubble Counters

    I've used similar, branded ones in the past and they seem fine? I'd be inclined to blame your regulator?..... Does it do it with any other bubble counters?
  40. Dan Crawford

    Deleted

    I have a rhinox 2000 in 160l tank and mine chirps too, no idea as so the BPS but I don't think it's excessive for this particular diffuser, the rhinox 5000 in my other tank doesn't do it though.

    Few questions about C02

    It certainly looks right pal, maybe a better type of media in the reactor? Tetra Bio Balls amy be more effective but i'm only surmising here as like i said, i have no real experience with them.
  42. Dan Crawford

    Few questions about C02

    It sounds like your reactor isn't doing it's job correctly? I've not used one but i'm sure you shouldn't have large bubble coming out of the spray bar.... Have you tested the effects using a diffuser?
  43. Dan Crawford

    New to CO2

    SamC has it right and i'd start at 1 bubble per second and see what colour that achieves in the drop checker then adjust from there. Good luck.

    Themuleous has given you some good advice there. One thing i'd recommend is checking your 4dkh solution, had some dodgy stuff and i was always in the yellow.

    CO2 Refills - Possibly a stupid question but...

    Hi mate, I have plenty of FEs, the dumpy ones are wider so if floor space in the cabinet is limited then a taller one might be better. The taller ones sit at around 650mm high and the dumpy ones about 550mm. Let me know if you decide to take this route and i should be able to sort you out.
  47. Dan Crawford

    Whats Going On

    It can't be the DC, it must be the solution IMO. I had a dodgy batch from AE but it was a very long time ago, my DC was always yellow.

    Really really struggling to get sufficient CO2 diffusion

    Hi mate, i'm glad it was my tank that tempted you to alter your methods.

    any recomendations for a co2 reactor?

    A drop in flow is generally the only issue but i haven't used one so i can't comment first hand.

    rhinox 5000

    IMO yes, an inline reactor wouldn't hurt on a tank that size. You can use whatever powerhead you like as long as it's rated high enough for your tank. Them hydo ones are good though, worth the money IMO. How come you want a powerhead? is the filter flow not up to much?

    Could these spurts or burps be just a build up of oxygen and other gasses which in a situation without the reactor in the line of flow would just be expelled into the aquarium without a noticeable burp?
