aquariumplants.com gave me good service and plants arrived in good condition. I'm looking at the Coralife 36" and plan to order from F & S also. Saw it cheaper elsewhere so look around, but I got good service and price from F & S on my Canister filter. You also might want to check out AquariumPlants own substrate. About $45.00 for a three inch layer in a 55 gallon.
