New tank, need a refresher
I'm just restarting my planted tank after several years, and I need a little refresher....
We have ridiculously hard water, so this time when I setup the tank I mixed 50/50 tap & RO water. I have a fresh Hagen KH test kit (I ran out of drops before since my water was so hard!), and I get 19 drops in before the 5mL of water is reasonably yellow... according to the directions this means my KH is 190 PPM.
To use CO2 level chart I need to convert PPM to DK by dividing by 17.86, correct? So 190PPM/17.86 = 10.64KH
My rested tap water meters out at 7.8 on the pH controller with a brand new, freshly calibrated probe.
So if I remember correctly, I want to turn up the CO2 until the pH drops to a level that indicates a good CO2 content, right?
Currently my pH controller is reading 6.6, but I still don't see any plants pearling ever. I only have one fish (bluegill sunfish) currently, but I don't want to go too low and stress him out.
Does it sound like I'm doing something wrong? I have all real easy starter plants like cabomba, hornwort, and anacharis.
Thanks for the feedback...
