ph

[b-ridge]

i am looking for ways to lower my ph without having to do a major water change. I checked my levels and there off the charts. according to the test kit it is 8.6+. I am running a 125 gallon sump with internal skimmer, a 75 gallon refugium all running my 240 gallon display tank. would a low tempertature or running carbon help lower my ph?

I would get another kit and try it before you do major changes to your tank. If things are alive in it then your readings do not seem right.

i recently had 2 fish die in a matter of 2 days. a lion fish and a blue tang. i just checked my alkilinity and that was high also with a range of 2.9-3.6

How low you want to get your pH too?

2.9-3.6 alk is very low not high

I figured 8.6 was high for ph. I'm just trying to find out what made my fish die so i can prevent any problems in the future. maybe the temp was to low for a blue hippo tang and my lionfish cause i imagine they like nice and warm temperatures

a guy from the lfs recommended i put a couple gallons of poland spring water to lower the ph since poland spring has a ph of 6.2

i wouldnt trust poland spring. whats ur ammonia at? did u test for everything else?

yes i tested for everything. ammonia was 0.1 but this is only a fowlr set up. everything else as far as nitrites and nitrates were low also. i am starting to believe it was the temerature that killed them cause my temp was really low. it was at 68-70
