Planted substrates are used for maintaining levels of nutrients. Flourite is a very good substrate, but the ADA aquasoils are far superior in looks and balance. Read the stickies for more information.
another question on substrate. if u use flourite, but want to have the pool filter sand look, can i just layer the pool filter sand over the flourite, or will this cause harmful anerobic bacteria growth and kill the fish?
I use soil master select. I'm rather fond of the color and consistency of it. It's similar to the turface that was mentioned. I do use supplemental root tabs though.
i have been doing research on substrate to start my tank too and i was wondering is the schultz aquaticplant soil ok to use with a HOB filter or is it light and will it float around and get sucked up?
