My PH out of my tap is 8.2 and my fish are fine. By monkeying around with it and trying to lower it, you'll likely do more harm to the fish than leaving it high. Where PH is concerned, consistency is more important than the actual number. An unstable PH that is constantly fluctuating is much more unhealthy for them and will likely lead to disease and death.
You in the middle of a Fish-In cycle. You'll need to test the water at least once a day. If your ammonia and/or nitrites ever hit .25ppm or higher then do a PWC
to bring it down. It's simple math . For example: Ammo is .50ppm. You need to reduce that by a little more than half, so do a 60% PWC
. If the number is too big to fix with one PWC
, then do one 50% PWC
, wait a few hours and then do another.
Once you go a solid week with 0ppm ammonia and nitrites then its safe to say the tank is cycled. Then you only need to do PWCs every week or two to keep the nitrates below 40ppm. Going forward, only add a few fish at a time and go a week in between additions to give the BB time to adjust to the increased bio-load.
Fish-In cycling is more work than Fish-less cycling because you have to keep doing the water changes or you risk killing the fish. Just be patient and diligent and you SHOULD be done in another 2-3 weeks.
