Default Re: CO2 system suggestions for a 75gl tank

This has been a very informing thread. I just got a ph controlled co2 system. I love it. I use a drop checker with 4dkh solution to monitor co2. I really don't care what the ph is set too. This is a discus tank so i don't mind a low ph, but my water parameters are 6.08PH, 5GH and 4kH.

Earlier in this thread it was stated that phosphates can alter the reading of a ph monitor probe. It was also stated that it can effect the drop checker results. Can someone go into more detail on this? What levels of phosphate have dramatic effects on the ph controller's reading? If using a 4dkH solution in your drop checker, does phosphate have any impact?

This is a great thread for anyone with questions about co2... lots of unasked questions answered here!
