Moving to an RO mix
My water here is rock. Even the water company suggests water softeners for our region to preserve appliances. To put it into perspective, I have to chisel the mineral deposits from my Rabbit's water bowl that build at the water line from time to time because it's quite literally a band of rock. (Started giving him bottled water, btw.)
So I felt bad for my plants and fish after reading about hard water here, and started to add RO water when changing water. To begin with, my GH=21, KH=13, and Ph=8 (always, day, night, even with CO2). I've been slowly adding RO water and now sit at GH=15, KH=9 and Ph=7. But I tested the Ph during lights out and it was creeping back up to 8. Can't be good for the fish, right? Is it normal for the Ph to do that when the CO2 is off during lights out?
As of now, my RO mix is 75% RO and 25% tap water, which puts my mixture at GH=5, KH=4 and Ph=7.
Photo of my tank, sorry.. battling BBA at the moment. I've added some new Philips 6500K T5 24W HO (x2) lamps that brought on the problem. Investing in a new CO2 tank and regulator because my present rig is full throttle and only delivering about 20ppm. My tank is in my signature.
Bump: You can see the deposits at the waterline in this photo.
