	filtration for really large tanks?
LMuha Mega Fish Posts: 908 Kudos: 1144 Votes: 183 Registered: 17-Mar-2003	I've finally figured out a spot where I can fit my dream tank -- one that's somewhere between 180 and 200 gallons. But I have no idea what sort of filtration is best for a tank that size. I have biowheels on all of my smaller tanks (55 gal., 30 gal, 20 gal. and 10 gal.), but am not sure that's what most people would do on a really large tanks. Any suggestions? Is a cannister the only alternative?

It also depends on how many and what sort of fish you have in your tank as well.

They provide the most efficient filtration, and are readily availible. And when he gets to Heaven, to Saint Peter he will tell: "One more Marine reporting, Sir! I've served my time in Hell."

I think it is a really good filter with a nice lower price. I have a new Eheim 2217 filter running in conjuction with a Fluval 204 on my 90g tank, and I must say both filters are great. The Fluval filters have an easy prime system, but just cant handle the high gallons that a Rena, or an Eheim, can handle and then some.

heaven2 Mega Fish Posts: 1065 Votes: 0 Registered: 10-Jun-2002	Another alternative is to have the tank drilled (only possible if its not tempered glass) and plumbed to a sump system designed to do both mechanical and biofiltration. Pros of running a sump sytem is that a constant water level is maintained in the tank (water loss due evaporation shows only in the sump not in the show tank), hardware such as heaters can be hidden in the sump, vast area for biofiltration, chemical media can be added if so desired. Water turnover is determined by the flow rate of the pump which returns water from the sump to the tank.

dextroze Hobbyist Posts: 69 Kudos: 86 Votes: 21 Registered: 07-Sep-2004	An alternative to drilling may be the "Customflo" system, which is _meant_ to be able to be used with wet/dry set-ups... http://www.pentairaquatics.com/products/detail/customflo_starter.htm and http://www.pentairaquatics.com/products/detail/customflo.html It looks like one version (I'm guessing the starter kit) goes for round the USD$40 mark online.
