I have just got a 56 gallon tank. I am hoping to have it heavily planted. I really appriciate any advice people have to offer. I have just added plants and have eco-complete as my substrate with a flora-sun bulb. I have added root tabs and the tank is 1/3 of the way full of water and has no heater or filter but i will be getting them is 2 weeks. One question i have is which filter to go with... i know i want a canister filter but i dont know what brand to choose and i also want to spend no more than $220 on it, any advice on this topic would be helpful. I am leaning toward a Rena xp4... how are they? Thanks for your time.
