Best Canister Filter For 125 Gallon Tank

Category: canister filter 👁 464 👍 66 ★★★★☆4.1

I've been into aquariums for a while and i know, GPH should be 5-10x the gallons in the tank; however, i just got a 120 gallon tank that came with two Fluval canister filters. the combined total GPH is 335. The manual says this will work fine for a 140 gallon tank.

In like manner, how much does a 125 gallon fish tank weigh full?

A glass 125 gallon fish tank that measures 72” x 18” x 20” will weigh 995 pounds when it is completely filled with freshwater. The same 125 gallon glass tank, on the other hand, will weigh 1,018 pounds if it is a saltwater tank.

At all events, will my floor hold a 125 gallon aquarium? For example, a 125 gallon tank, on a wooden stand, placed perpendicular to the joists up against a bearing wall, will often be okay without any additional structural support. If your tank is over 125 gallons, then it is likely that you should consider adding supports under your wood framed floor.

In spite of that, what is the best filter for a 100 gallon fish tank?
