I've had a 20h nano running for 3 1/2 months now and everything seemed to be doing ok, until i noticed my PH was a little on the low side 7.7 so i thought i would dose Kent Marine Pro Buffer dkH
daily at 5ml a day after the light had come one, i was also at the time dosing Purple up not realizing i didnt need to with the Kent buffer, so i decieded to stop i havent had a chance to get my water tested for Alk
or Cal yet and do not have the proper test for those, i did call a semi-local fish store and gave this info to someone over the phone and basically said i was way over dosing and was causing a ph shock to my corals because there are all closed and not opening, some various Zoa colonies some xenia, a colt coral and some mushrooms and kenya tree, all have reacted poorly in the last few days. so i did a 25% WC
two days ago and another 25% today but havent noticed much improvement, i plan on haveing the water tested tomorrow at the latest if i cant get out there today, my question to everyone is does it sound like im on the right track.

I also started to mix my own saltwater useing instant ocean salt mix, letting it mix overnight with the same temp as Display tank and i was using pre-mixed saltwater from another lfs
before hand, but didnt seem to notice and difference until the daily dosing began.
