Plants Melting/Rotting>?

So my tank has been setup now for at least 6 months or so. 100g, with 48" t5ho hagen glo lights, hanging about 6 inches above rim of tank. Pressurized Co2 with one of GLAs inline co2 diffuser. Rena xp3 and Fluval 305 for filtration. 2 drop checkers (one on each end). Koralia nano to help push co2 to opposite end. Substrate is a mix of eco-complete generic (no nutrients =(. ) and normal gravel. I dose Ei every other day. Weekly 50% water changes. Now that that is out of the way. My plants of course went through the normal new tank stage, some died some made it and most flourished. As of late though ive been battling BBA, some hair (from when i wasnt getting constant co2 into tank) and most of my plants arent growing very well. My cabomba seems to be rotting near the base, same with my L aromatica. My M. minuta has pretty much stopped growing and slowly dying. None of my plants look great aside from my floating riccia and subwassertang heh. Any advice would be great. Thanks, Matt

This can't be doing much in a 100 gallon tank! I would suggest as a start buy a larger unit.

Maybe dose the tank with Excel for a few days to destroy the BBA. When I had an issue with a BBA (twice) I dosed Excel 4 caps in morning, 4 caps at night for 3 days, then 2 and 2, then 1 and 1 over the next two days. I have a 46 so you would need to double that. BBA was wiped out!

How many watts of that T-5 HO are you running? Try lowering your light? 1.2-1.4 watts per gallon of T-5?

Oops forgot that info. 2x 54w T5 HO. So just barely 1.0 wpg, but its HO so wpg doesnt mean a whole lot. Im starting to think i could use a bit more light but not sure. I do have some larger powerheads but imo they are too much and just push the plants over.

You have a medium lit tank with floating plants. That would make me consider it low lit (to very low lit depending on the density of the floaters) for submersed plants. I you want to continue with floaters then you will have to increase your lights for submersed plants.

If you have a choice, you have a problem, till you elect your choice. No choice, no problem, only consequences, learn to live with them.
