I have the Red Sea Pro system which came w/ everything needed to set up CO2 except the tank.
We've had it running for 2 days now.
There was a drop checker that came w/ the system and indicator liquid. The bottle is just labled "indicator liquid", not 4dKH or anything else. Also, the instructions said to use 1mL of tank water, not distilled. The instructions also say that optimum CO2 levels willl be 15-20 ppm, I thought that we were shooting for 30ppm... ??
Yesterday I had a hard time getting the liquid to turn the "right" color but after a few hours it did, and the plants started pearling and were "happy". Fish seemed happy too, everyone was swimming around and making friends. This afternoon, the drop checker reads as if there was still the same amt. of CO2 in the water as there was last night, even though the CO2 system turned off last night around 2 AM. My fish are still happy and healthy, not gasping for air or hanging out by the filter flow. Is this normal to not outgas CO2 at night??
I want to get as much CO2 in the tank as possible to allow for optimum plant growth without hurting my inhabitants.
Any suggestions? Should I just trust the DC and fish behavior? Turn the CO2 up a little bit when it comes on and see how the fish react? Just leave it alone....????
I tried reading Ph and Kh but I only have a strip reader for Kh and it's not too accurate I'm assuming, because I have an actual Ph kit and it differs from the strip's reading for Ph by about .3, and with the numbers I got for Kh and Ph according to the chart my fish should have all been dead or gasping for air and they certainly were NOT doing that. I tried to buy a Kh kit last night but the Petsmart closest to home didn't have one in stock.
Any suggestions? Thanks!
