my PH levels are seeming to drop dramaticly, for some odd reason. i do a 10-20% water change a week. check the ph. and add buffer as needed.. but not to exceed the dkh levels.. one morning my ph was like 7.6 or so, so over the course of 2-3 days i brought it back up to 8.4.. but to find that two days after it went back down to 7.4 .. i now have it back up to 8.4 with the dkh level at 10 or 179kH .. dunno why its doing this
any ideas?
