10G Rimless(BBA problem, help pls)

Hi, i have a 10g rimless AGA aquarium with 46 watts of 6500k cfl lighting. I dose leaf zone once a week and excel 3 times a week. Plants include a large sword and some watersprite and red ludwigia. The past month BBA has gone rampant on my sword and i can't seem to get rid of it.. any suggestions? There are only two fish(bettas) in the tank and 1 shrimp. Filtration is a simple ACmini hob filter. Nitrates are 20-30ppm, waterchanges are 30-40% per week.

Thanks in advance.

do you have any co2? you need co2 and preferrably dry ferts with that light. you probably could use more flow too. no co2, low flow, and inadequate ferts = BBA.

Oh and the substrate is flourite black sand if that helps?(1 bag mixed with some reg gravel to reach 2" depth).. No co2 yet. So basically too much light for too little co2, and too little flow?

primary cause is no co2. low flow could be a problem. is your water like stagnant in some spots or is there circulation all around?

flow is pretty low, there are deadspots, the plant that is affected is right in front of the filter though so it gets lots of flow. I hate this stuff! only spare pump i have is a 250gph power head lying around and i think that would be over kill

yeah CO2 is the culprit

umm 2 female bettas right? or do you have it divided?
that has caused major flow issues for me in the past. . .

So my only real solution is to add co2? no a male and female, shes in a large net breeder in the tank, but part of the bioload so mentioned her. Eventually plan to breed them.
