Co2

I just set up a pressurized system on my 55gal tall tank. It has never had CO2 before. I'm wondering if any one can tell me a good starting point for the bubble count. I have a PH of 6.8 so I don't want to run it down to far with a high CO2 out put. Any help with this would be great. Thanks

Send a message via MSN to jjp2
with 3+ wpg and CO2 you will need to fertilize the water collumn, most go to EI at that point or their own variation of it. You should get a drop checker to help with CO2 monitoring/adjustments.

If you have a soleniod, start at 2-3 bubbles per second. If you do not, start at 1-2. Adjust based on fish/plants and drop checker.

Ok that sounds fine. I just don't want to have the PH drop to fast. I will get a drop checker tomorrow and then I can get a better idea of what is going on.

A ph controller will do the trick.

co2 related ph drops are insignificant and irrelevant. Ph drops associated with co2 do not effect fish the way that a ph drop from say, driftwood or other acids would.

I've always found pH controllers to lead to an uncontrollable spiral of non stop adding of buffers etc. to keep the tank from spiralling out of control...wow say that 3 times
