About a year ago I did a comparison on 5 different methods of checking Co2 levels, here's what I found. Remember that the Co2 in your tank will depend on your PH and KH readings, any test kit that relies on tank water for a reference solution could show errors if there is anything in your tank...

Hi, It's been sometime since I've used the JBL kit, but basically if the indicator is showing 'Green' then the Co2 level is good. Blue shows it too low and Yellow means too high and things are getting dangerous for your fish ! Here is a link to a copy of the JBL colour chart. JBL Colour...

Only for as long as my current subscription lasts ! I've found that the only part of the mag I read are Georges articles ( always well written and informative ) the rest of the mag remains pretty much unread, including articles discrediting high tech tanks and the EI method in general, even...

As James has already said, you may well struggle to get this extinguisher refilled. Most places won't touch the black ones any more as they no longer conform to the standards. I've posted this link a few times .... once more won't hurt ! Ebay Fire Extinguisher Guide This is probably not what...

If you do a google search on 'aquascape' and 'golden ratio', you'll find a number of excellent articles that explain how the golden ration can be applied to aquascaping to produce an effective composition. George Farmer has also written an excellent series of articles that cover the basics of...

What lighting do you have over the tank (how many watts per gallon). If you have low light, most of the common 'low' carpeting plants will tend to grow tall, rather than spread out over the substrate. Dwarf sag is fine in larger tanks, but in smaller tanks it may actually grow taller than you'd...

But a few pence spent on a non return valve gets around that problem. Acutally I'd strongly suggest including a non return valve on any co2 method (Pressurised or DIY/yeast systems), no matter what diffuser/reactor is used. It will stop any possible syphoning when the yeast slows down and the...

Manufacture date should be actually stamped into the metal. I believe it should actually be on all pressurised gas canisters. They on Co2 fire extinguishers and are even on 500g JBl bottles, you'll usually find it toward the top/neck of the tank .... Somtimes the date format varies 03/06 or...

One thing to remember if buying a second hand cylinder or renting one, is the date of the pressure test. AFAIK tanks are usually good for 10 years from date of manufacture, this date and the date of the last test (if different from manufacture date) should be stampped into the tank, somewhere...

It's probably not what you want to hear, but DIY/Yeast based Co2 is not really suitable for a 240Ltr tank, especially if you are hoping to get a good and stable Co2 level. However, Nutrafin recommend 1 canister per 70ltrs. Based on that you would need 3 or 4 canisters. Even with that I doubt...

My 2KG (that's about 70 oz) fire extinguisher cost me £15, and £15 for each refill. About the same cost, but over 3 times the gas, so it lasts far longer. And if I ever give it up, I can re-attach the horn and put a fire out with it :lol:

I dont want to knock your reactor, it's a nice little DIY solution to dissolving CO2, but I have to say that I disagree with your earlier statement about "1: I didn't spend £40 on £1 worth of glass.". There is no need to spend £40 on a glass ceramic diffuser, in fact you can easily find...

Almost as bad as one near me. When I asked if they have Co2 ..... The replied "No, we only do carbon dioxide". Then she tried to tell me that 'co2' or 'carbon dioxide' was the difference between a pressurised system and a yeast based system. .... I laughed .... left ! :huh:

That would really depend on if they were sold as a 'bunch' or 'pot'. If they are sold per pot, I would expect them to have been pot grown and have a deleloped root system, if they were described as a bunch I would be perfectly satisfied with cuttings. So why buy plants with roots when they'll...

That's exactly what I did ... second hand ones from Ebay. Cheaper and you dont feel ripped off when you exchange them! I here there may be a couple of suitable bottles going onto Ebay fairly soon :lol:
