Do you make a larger version of the EXT canister filter?

It is always best to use multiple filters in case one quits working. But currently we do not make a larger EXT filter.

    concept is great.Have a EXT but had a few problems setting up.The clamps supplied do not work. They are to small and rigid. Replaced with stainless steel clamps.Had a problem getting top to seal properly.Solved with using more silicon lubricate than supplied as clamp pressure cannot be adjusted.When received finishing pad was missing.Supplied my own.Power head could not produce enough pressure to lift water from floor to aquarium top.Lifted unit to level of bottom of aquarium.Working fine but not hidden.Concept is great but could use a more powerful pump.This is a backup unit for a 175 gal. tank.
