I'm coming back into the hobby after a 14 year absence, so please bear with me.
I'm going to be setting up a 90 gallon low tech planted tank. I have an Eheim 2228 canister filter rated at 277 gph and four GE 32W T8 6500K bulbs which will sit directly on the glass top, 21-23" (
) from the substrate.
Planning on starting with a lot of different Crypts, Java Fern on driftwood, Vallisneria, Hygro, Dwarwf Sag, and maybe a few Tropica Swords.
Eventually would like to have a couple Angelfish, 20 or so Cardinal Tetras, and some Corys. Maybe also a few Blue Rams.
I've purchased 4 15.4 lb bags of Flourite black, 1 15 lb bag of Flourite black sand, and a 50 lb bag of Black Beauty 20/40 grit blasting media.
My main question (of many) is do I layer these different substrates, and if so, what goes where?.... or just mix 'em all up?
The last time I had this tank set up was in 1999, and that was with the Eheim combined with a tank-wide undergravel filter driven by a couple powerheads. The plants never did too well in those days...
Secondary question...will I need more filtration and/or water circulation?
Thanks for reading, and special thanks in advance to all who respond with advice!
