No PH change with DIY CO2
AGree probably the yeast. Also, it is possible to kill the yeast - I am
told - by using too hot of water. I am told you need to use slightly warm water but definitely NOT HOT. Also, cold water is supposed to work, just take longer for the yeast to wake up. Before you buy more yeast, try cooler water. Bob "Rick" wrote in message a... "Dave M. Picklyk" wrote in message ... I wouldn't buffer the water with baking soda (unless you have acidic water already---but 7.6 should drop to about 6.8 or so which is fine for most fish)--if you do that, you cannot accurately measure C02 with KH and PH readings without strictly letting your water be carbonate buffered (natural buffering capacity of the water). Also, some natural water supplies have high phosphate content, which invalidates any calculations for C02 readings including C02 test kits. Just a thought, Dave. I only buffer the water in my Cichlid tank where there is no CO2. In my 20g tank I checked again this morning and the co2 is happily bubbling away via the Rena bubbler and my PH might have dropped from 7.6 to 7.5, hard to tell with those test kits unless you get a larger swing. I'm not going to worry about it but I would have liked to have seen something constructive happen like some pearling. I also have a 1 gallon jug hooked up into my 77G tank. I hooked it up two days ago and have yet to see a bubble. I have added another 1/4 teaspoon of yeast yesterday, nada, added another 1/4 today from a fresh package. I hooked up another one gallon jug and added fresh yeast to it, both jugs are hooked up via a t connection. On the first jug if I removed the line from the anti siphon valve and held it under water while I vigorously shook the jug I would get a few bubbles and then nothing so it appears to me that maybe the yeast is no good. This is wine making yeast I am using. The package was opened about 10 days ago for the 20 g tank and then stored in the fridge, does this stuff go bad?? I checked all the fitting by immersing them underwater and found no leaks. Rick |
