hey all.
i am currently setting up a 700 gallon freshwater stingray tank. the tank is going to have a heavy bio load as well as requires HEAVY mechanical filtration. i am not at all concerned with chemical filtration (carbon/ion exhange media).

i am currently on the fence on whether i want to build my own large wet/dry system (which i have done in the past with great success on my 180 gal tank). the wet dry's mechanical filtration would consisted of 100% of the water first flowing through a series of 32" 100micron mesh filter bags. the water would then flow over a combination of bio-balls/ceramic beads for bio filtration OR

Whether i should buy a product on the market called Xtreme biofilter. its basically a souped up bead filter system traditionally used for pond filtration. instead of using beads they use a mcuh better patented filter media that produces huge surface are for bio-filtration and exceptional mecahnical filtration. the benfit to this system would be that it would be a closed system AND i would never have to clean the filter media because it has a backwash feature such as a poll filter does which agitates the media, knocks off all the waste and gets washed down the drain!!!

can anyone who has a large home-made wet dry post photos of it please? any input would be appreciated! thanks!!!!
 
why not just use a pool filter plumbed in, the sand is great for bio and mech filtration, and you still have the backwash feature, just wondering?

never thought of it. that may be an option.
 
i just know this time of year, around here atleast, a lot of the pool stuff is on sale, and if you can find one of the 220v ones it will actually use less power/lower amps, and will provide great flow. it'll kinda be like a huge fluidized bed filter with a backwash option. When i move back to my other house i am deff. gonna build a 700 to 1000 gal tank and use one.
 
Make sure the backwash feature can practically be used indoors. Having used the backwash feature on a few pool filters as well as a few pond filters, not all of them can easily be used indoors...

Just because it says on the side of the box that you'll never have to clean out the filter, don't think it's true. Chances are it will not clean itse;f out nearly as well as it needs to be cleaned out...

Pool filters a re a great idea, but when you get into teh practicality of the application they quickly start to be problematic. Pool filters are not designed to remove large quantities of waste...

Having kept many hundreds of gallons of tanks over many years, I've never once owned a tank that lacked enough surface area for enough bacteria to grow on. Because of that I'm not very inclined toward fancy bio medias or Wet/Drys.


I would consider making built in filtration... something like a false wall a few inches in front of the actual wall that doesn't go all the way to the bottom... the gap at the bottom would act as the filter intake...

Put a pump at the top of that false wall blowing out... Now it's up to you to plan the middle in such a way that water moves through media and the media can practically be cleaned...
