    What does this tell me?

    I love all the data he gives too - it was my one disappointment with the Green Machine book that they don't give that plus the latin names of the plants in each tank. I find it interesting Amano always quotes dissolved Oxygen too. We know this is super important for bacteria (and other...

    Aqua Medic Co2 Reactor.... Which One???

    Are Aquamedic still doing this only with a 12/16mm inlet/outlet tubes?

    CO2 in aquarium and atmosphere

    Nice to see Clive posting a mini lecture - I've missed that lately :D. That does make things clearer! So I think you are saying that there are more water molecules per given volume so 400ppm in air translates to 5ppm in water due to the higher density of water molecules? Atmospheric...

    CO2 in aquarium and atmosphere

    Exactly Scott - its interesting that we have 5ppm in the water and 400ppm in the air yet we are forced to buy CO2, presumably because of the relative insolubility of gases in water compared to air. But in concentration terms there is so much more in the atmosphere - no wonder emersed growth is...

    CO2 in aquarium and atmosphere

    I probably learnt this at school, so please excuse the dummy question. Why, if we have nearly 400ppm CO2 in the atmosphere (see: http://www.guardian.co.uk/environment/2008/may/13/carbonemissions.climatechange), do we need to administer CO2 to the aquarium to arrive at 30ppm? Why does it...

    Drop Checker Test - 'Teardrop' versus 'Chameleon'

    Really nice test Andy. All you need to do now is get CalAqua to supply the Oracle DC for comparison with the normal Chameleon (http://www.calaqualabs.com/oracle.html). I suspect the 2 hours delay with the Chameleon is more like one hour, but I'm not sure. Would have been interesting if...

    Reactor question

    Thank you for your a1 answer Matt :wink: . I think you may be right. My valve is clear platic and I can see water in it. So which valve should I try (I'll try anything, even the 9.99 ADA check valve)...

    Reactor question

    Interesting, mine has done it for 2 months now, but didn't do it first day (at least I don't think so, although with all the excitement - filter leaking etc. I forget). How to clear it - blast the CO2 through in a stream? Or should I change my one way valve - its quite a cheap plastic thing on...

    Reactor question

    If the filter media is new it tends to give off a lot of bubbles initially. You should just bleed it off regularly. I've got the smaller size one (like LD linked to) and I had issues the first week with gas build up. Since then its been trouble free and I only use the bleed valve after filter...

    Avoiding Surface Film in Drop Checker - any tips?

    I think you are right, but I was wondering, should I be sterilising my DC or something to try to stop it happening - i.e.. is it because I've got biofilm build up on the glass that spreads accross the surface?
  11. Ray

    Avoiding Surface Film in Drop Checker - any tips?

    No, 4DKh, but I should have been more precise above - the surface film is not on the 4DKh/reagent mix, it is in the funnel where the air pocket in the DC meets the tank water outside.

    Avoiding Surface Film in Drop Checker - any tips?

    Does anyone else get this? Apparently although surface agitation is enough to keep the surface clear, it still forms in my DC. Once it does I get a nice yellow result 24/7 which is confusing. If I re-fill the DC with air it clears but re-forms quite quickly unless I rinse it out. How to stop...

    New design of drop checker

    Clever - faster response time, easier to read, just when I thought I already had a drop checker you come out with that - something for the Xmas list I think! All we need now is one with a digital readout :D But seriously, did Cal Aqua perform any tests to see how long this one took to...

    Overdosing EasyCarbo?

    Great, thanks guys - very helpful :D . I think I'll run with 4x dose for a week and see how it goes. How long before the algae starts to suffer? 2 or 3 days?

    Overdosing EasyCarbo?

    Anyone any experience of this? Instructions say go to 2x in a heavily planted tank but DO NOT EXCEED THE DOSE. I have no livestock, and I know about fissdens, vallais, etc being effected. Has anyone tried going higher? If so how much higher? Also if the objective is to nuke algae should I...

    In Line Reactor - Aquamas

    Thank you James, that is extremely helpful. Flow is certainly good through the Aquamas - mine is also on a 2028 and after 10 days operation with full media load, Aquamas reactor and Hydor inline heater this 1050lph filter can fill a 2l jug in 9 seconds which is 800lph real flow. It is a bottom...

    In Line Reactor - Aquamas

    OK, just like the Aquamas so you have the same problem. Inherant issue with the reactor concept except perhaps the Cal Aqua one. I wonder if a valve exists that bleeds air but not water?

    In Line Reactor - Aquamas

    Yes, now - must admit I did plumb it in wrong to start with :oops: Cue another half hours swearing inside my cabinet. How long are you getting out of 2kg on 2bps with this reactor? Its got noisier, I wonder if a clean would sort it. Or wack the CO2 right up to clear any blockage! My other...

    In Line Reactor - Aquamas

    All seems in order hose wise - no kinks, no bypass, I can bleed any air out but the noise happens when the bubble exits into the cylinder so having air at the top is not the issue. How many BPS are you running your at? I'm running at 2 per second at the moment but it does go quieter if I...

    CO2 Reactor for my tank??

    No wastage from the in line Aqaumas or Cal Aqua reactors Matt - 100% dissolved, although they are not exactly budget (60 Euros for the medium Aquamas, only 38 Euros for the small one: http://www.aquamas.de/products/Reaktoren/CO2-Aussenreaktor-fuer-Aquarien-bis-etwa-500-Liter.html, check AE fro...

    In Line Reactor - Aquamas

    Mine works well - 100% dissolved - but is annoyingly noisy - I'm running at 2 (large) bubbles per second and each one goes "pop" as exits the tube and enters the reactor body. I can count bubbles by listening without having to open the cabinet! Is it the same for other people using this? Is...

    Mazzei venturi

    So you are planning to use one of these to distribute CO2? http://www.mazzei.net/products/injector_info.htm But not necessarily off a filter outlet, possibly off its own pump? It looks very similar, to me, to the venturi diffusors you can already get? I'm looking forward to this too...

    CO2 Kit Not working - Solved

    Re: CO2 Kit Not working - Please Help! Crisis over. Erm, yes, yes you can.. :oops: :oops: Its all working fine. I took the solenoid off and nothing, then the needle valve and "hiss" as soon as a losened it. So I put them both back and its working! I seem to have misunderstood how this...

    CO2 Kit Not working - Solved

    Re: CO2 Kit Not working - Please Help! I opened the valve on the regulator and then on the bottle. Or maybe vice versa, I forget. As soon as I did the two needles shot up to the values shown. I can unscrew the needle valve until it comes out in my hand and no difference. The non return...

    CO2 Kit Not working - Solved

    Hello, I've finally unboxed my Aquamas CO2 Starter kit. The in line reactor is the business - really excellent - but I'm having some issues with the regulator. I connected up the regulator and the solenoid and turned on the gas at the cylinder. The flask is full at 70bar, so that's good...

    New design of drop checker

    Or, I'd like a 4DKh drop checker incorporating a digital readout - it could give you the CO2 in ppm since it knows the KH. I'm surprised nobody has done that yet. Must be more complicated than it sounds...?

    DIY Co2 - switching off at night

    Never tried this but I guess you could add a T piece with a solanoid on one fork, diffusor on the other. Set the solanoid to open at night, allowing the CO2 to vent rather than going through the diffusor.

    Drop checker green???

    The reactors should be up to it. The general advice is to start at 1bps and move slowly up from there until you get the lime green. 600L is a big tank so will likely need more than 1bps, but each bubble counter is different, its not a precise measure. You need to allow a couple of hours...

    Help with CO2 kit choice please

    Good news, I can afford the AquaMedic stuff because I've found somewhere I can rent a 2kg cylinder for less than the cost of a refil at the LFS (called a telphone number on a cylinder behind the drinks machine at work) :D This is very beneficial for my budget! Is it worth paying 40 EUROS extra...

    Help with CO2 kit choice please

    Oh boy look at that branded Aqua Medic stuff it is soooo nice, just imagine opening the boxes, look at that pulse powered solenoid - only draws current when it switches so your valves don't get hot. :? I was going to go for the Aquamas professional starter kit (fortunately I have just enough...

    Cheap CO2 reg - thoughts?

    CO2 when to turn it on? (NOW GENERAL CO2 QUESTIONS)

    Yes it will. However, the chemistry behind it is such that it does not seem to bother fish - they can easily adapt to CO2 induced PH changes.
