Based on another thread:
My planted tank is 18 gallons (10x20x20), lighting is 15w T8 5000K, 13w CFL 6500k, 10w CFL 6500k.
last week I changed my substrate from 3-year-old, mulm-caked gravel to flourite over peat moss.
I have been dosing:
Seachem floruish excel (1.875ml 1x/day)
Seachem flourish (2ml 3-4x/week)
API leaf zone (10ml 2x/month)
prior to my substrate change my water parameters were:
dKH - 11
dGH - 16
pH - 7.8
Nitrate <15ppm
Nitrite 0ppm
Ammonia 0ppm
Phosphate 1.3ppm
Based on the formula above my CO2 concentration was 5.25ppm CO2. I had a pretty bad BBA problem.
Since I've made the substrate change I have been dosing with Seachem acid buffer in order to remove KH. I'm also on my second go-around of an API water softener pillow to decrease my GH. I added peat to my substrate as well as run peat in my canister. I've increased the bioload in my tank by adding a botia striata (zebra loach) and 3 tiger barbs. All of this with the intention of softening the water and lowering the pH.
My current water parameters are:
dKH - 4
dGH - 8
pH - 6.9
Nitrate <10ppm
Nitrite 0ppm
Ammonia 0ppm
Phosphates <0.25ppm
Based on the formula, my CO2 concentration has increased to 15.15ppm CO2.
Does anyone know the effect dosing excel has on CO2? I understood it to not effect CO2 concentrations, but add an available carbon source to be used in photosynthesis instead of CO2.
If I keep my phosphates down, how much of an effect on the BBA will I have? (there is very little BBA left after my plant & driftwood cleaning/substrate change out).
It also seems to me that absent CO2 infusion, lowering my pH from 6.9 to 6.5 while keeping my dKH at 4 will increase CO2 to 38ppm.
Are these maximum concentrations, or is this formula actual concentrations?
CO2 ppm = 12.838*dKH*10^(6.37-pH)
