if it helps, i recently tore down my fluval flora. 26 watt cfl, pressurized co2, ei dosing. when i first started i had an algae outbreak. i tore the tank down cleaned everything, increase co2 and everything went smoothly from there. bubble count doesnt matter. whats more important is how your diffusing co2, water flow, your fert dosing, and balance. balancing my fluval flora, i changed the direction of my filter outflow, put my diffuser in a better spot where i could see the co2 bubbles being disperse thru the whole tank via water flow (later upgraded to an inline co2 atomizer), dialed in my ferts using the calculator, and increased co2 gradually until my drop checker turned green within an hour. bubble count only tells you how much co2 your using in YOUR setup and is only relevant to you. my bubble count was 4 bps. some ppl will tell u 1bps, 2bps, 3bps, doesnt matter.
