Here at KiwiPetz we run Aqua One designed banks which consist of three large tanks with a sump underneath with a total of around 450L in each bank.
We (I :lol: ) clean these manually each week, siphoning up the poop, draining the sump (easiest way to remove water for us) and then topping back up again. Each bank takes me approximately 40 minutes to clean.
Aqua One banks are able to be supplied to the public, however must be ordered through a store (if they will sell you one), from memory they are a few thousand with all the componants needed. They are special ordered from overseas so usually take a few months to arrive. Setting them up is a matter of assembling the stand, fitting tanks in, putting the plumbing together and plugging it in.
Aqua One have changed their design recently however, and most are now coated silver with lift out and slide in fronts, as opposed to our system which is black with magnet fronts which click up to the underside of the tank above. Aqua One seems to update their design regularly.
