20gal lighting suggestion
I'm considering buying a 20g high (24x12x16) to replace my 10g planted tank. The 10g has done really well with the plants showing good growth(hygrophila, Vallisneria, Brazilian Pennywort). The tank is definitely low-tech : standard gravel, no co2, flourish comp once a week, 2x13w 6500k cfl.
In the 20g, I was planning to use some of those plants. Also maybe soil substrate, if not I'll go enriched, but still low-tech. Big question right now are the lights. I can get my hands on two type of hoods cheaply : 2x incadescent (thinking of 2x15w cfl, or 2x23w if I can get them to fit), of the standard 18w 24" T8. Which one should I go for ?
