Getting a 20 long. Just a few general suggestions needed.
Hey guys, I'm getting my third tank in my bedroom, fourth in the apartment tomorrow hopefully. I decided a 20 long would fit nicely over one of my dressers, and seeing as I'm upgrading my 29g's lighting soon, I can use the 30" twin fluorescent tube strip light over this tank.
I'm also thinking of putting 2 or 3 clip on 6500k 23w compact fluorescent bulbs over it, for a total of 86 or 109 watts. This would either technically give me 4.3 or 5.45 watts per gallon, although I know the cfl bulbs aren't as efficient (however they ARE cheap and the ones at my work look nice). Even assuming the efficiency of them are as low as 50% with restrike, I'd still get 3.15 or 3.725 wpg respectively.
So here are my questions:
I wanted to do a simple aquascape using only stones and a few plant species. I could either get hairgrass or pygmy chain sword near me for the grassy look I want, I'd rather have hairgrass, but I hear pygmy chain sword is easier (never tried hairgrass but chain sword grows for me). Is it really that much of a difference, and with this lighting and Excel, how fast could I expect either to carpet the whole tank?
I also wanted it to mainly be a species tank with a schooling fish and maybe some rcs, what common species (I'm talking petsmart/petco fish, they're the only fish supplier close to me) would be able to stand alone and hold attention, along with schooling tight?
Would DIY co2 be sufficient?
