Hi Everyone- I am doing my first full on planted tank and am wondering what substrates you guys have had success with. I currently have forty pounds of caribsea eco complete for the planted aquarium but am needing more depth in the rear of my tank. I dont know if it would be beneficial to add some sort of laterite or flourite blend. There are a million substrates on the market so I would appreciate some of your opinions.

I plan on finding a dense carpet forming plant to cover the bottom of the tank.

FYI: I am planning proper macro and micro nutrient supplementation. I will be running a diy co2 set-up. Lighting is low using 30 wat t-8 powerglo, will increase if find necessary. Tank is 46 Gal. I plan on getting a firm grip on the cycle of a planted tank before I purchase my discus.

Thanks All!
