It's been a while since I have been on this web site, and have had very little to report about my aquariums. But, now I am within two months of setting up my 75 gallon and I am very excited. I would like everyone's input on some of the setup. First off is canister filter, right now I am leaning toward a Rena, but also like the Eheims and the Fluvals. Second is substrate, what is everyones suggestions? I would like a fine substrate that can be planted if I decide to do that. Any other suggestions would be appreciated.
