20 l bba

So i have a 20 gal long with a coralife twin 18 watt bulb fixture 4 inches above tank rim. I have the tank planted with different mosses and trying to get dwarf hair grass to take off. I have root tabs in and have been dosing a little phosphate and potassium to help the plants use the nitrate from my crs and cbs shrimp. I have noticed that i am getting some BBA on the tips of the grass but not so much on the new growth emerging from my ADA substrate. I have the ability to supply pressurized co2 but read it isn't a good idea with CRS and CBS. I use RO/DI water remineralized with Seachem Equilibrium. My TDS is 150. My question is what should be my ideal conditions? should i co2 the tank, should i fertilize, how long should my lights be on? I just hate BBA.

I was under the impression that excel or adding CO2 could harm my CBS/CRS shrimp. Especially since 5 of them are berried. I am looking for a cause to this. I virtually have no nitrate, about .1 ppm phosphate. I am more interested in what i should be doing with my light that i have for the tank or a fert regime that will work for having my CRS. Mind you i also do a weekly 5 gallon water change.

BBA is caused by low CO2 levels.

I dose Excel at half the recommended amount with an eye dropper. Not much progress on my bba... yet.

How I feel about non-planted aquariums.

A small dosage of Erythromycin will take care of any cyanobacteria.
