ph trouble

[oliver moggridge]

hi im just wondering if my tests are all ok here they are (NO3 50, NO2 1, GH 16*d, KH30*d, PH 6.8, CL2 0.
my tank is 100liters with a diy co2 system.

No problem with your pH. The KH should help buffer any dramatic change in pH from the CO2.
Your Nitrate (NO2) is a bit high. It should be 0. I'd do a water change to get it down.

Your Nitrate is a bit high and you should be reading 0 for Nitrite in a fully cycled tank. Did you test for Ammonia? Don't worry so much about pH since stability is more important than the actual number in the vast majority of applications.

This may help some. http://www.aquariumadvice.com/forum...-but-i-already-have-fish-what-now-116287.html
