high ph

Rate this Entry
For the longest time my ph has been impossible to keeep up at 8.2 and we had to add buffer every day. we changed buffers and now the ph seems to be 8.6 or higher and doesnt seem to want to come down...
What should we use to lower the ph slightly???
Thanks Marc!!!

    can we get some more specifics about your tank? what size is it? how long has it been running? what is the calcium and alkalinity at currently? also what is your maintenance schedule like?

    never chase ph leave it alone!! so many factors in ph swings, oxygen levels in house and other things. what was low to you. i run a 150g sps tank full of colonies and my ph was 7.4-7.5 with no real probs then it started dropping to 7.0 stressing stuff out. so i added a kalk reactor and now i hold steady at 7.7-7.8 abnd all my coral and fish are fine. what im saying is unless its extremly low let your tank do its thing, stability is better than parameters swinging around.

    I would stop dosing additives and possibly do several smaller water changes through the week if it is really worrying you. Also what buffer did you use and what buffer did you switch to? I am just curious about that

    How are you measuring pH? A meter or a test kit? What are your other measurements of salinity, alk, ca, and mg? And how are you measuring all of these specifically?

    Stangchris is right on. Make sure your alk, mag, and calc are in their proper ranges and walk away. My pH floats around 7.9 no matter what I do, and only gets slightly better if I prop the windows open on the few days in Texas where the temperature allows for that.
