Pondering my kH/Co2/pH balance
Okie dokie <--- Yes I'm a dad.
- Orphek Atlantik 18 inches above water. Par at substrate in middle of tank 130. Par at corners 20. Currently running only 8 hours to keep algae at bay since the tank has only been set for 1 month.
- Mr. Aqua 500 & ADA ES-1200 both running from the same side directing flow over to Vuppa-1 surface extractor.
- 5lb Co2 running with customary glass diffuser. Soon to be replaced with an inline for better Co2 efficiency. Apex turns the Co2 on 1hr before lights are on and turns Co2 off when lights go off.
- Just started dosing PPS-Pro this week. Starting with half the recommended dosage(5ml).
I use RO/DI water for water changes and adjust gH & kH with Equilibrium & Baking Soda respectively...attempting to stay in the 4 range
kH = 5
gH = 5
pH reaches ~7.2 by morning with lights and Co2 off.
So here is my first question.
I do have a Co2 drop checker with indicator solution that only gives the right color(green) when I use enough Co2 that my pH reaches 6.2. My understanding, according to the Barrreport CO2/pH/KH table is that 6.2 should be too high of Co2 concentration. I should be shooting for somewhere in the 6.8 range. But I get no pearling at that level.
Throw out the chart and go with what the plants and drop checker say?
