multiple tank filtering question..
guys, i am planning on setting up a 5 (29g) tank.. The one problem I don't have a good solution for yet is an economical way to filter them all. I was
considering a single wet-dry filter, but have no idea how to start and how the plumbing works, as i don't have experience in doing the plumbing..

this is a similar question that i got it off from the internet and edit some of it.. if you know some links, please, post it here, for my reference..

help me understand this better.

you want to do 5x29 gallons, correct?
what will these tanks be used for? breeding? display?
either way your going to want to drill them and plumb them with PVC to another tank/wet-dry. reason i say "another tank" is because thats what i would do. i would builb my own sump from a tank and put different media in it like bio-balls and even a media reactor with carbon.

I'd be a little nervous about putting all those tanks on one filtration system. You've given all five tanks a single point of failure and made them all identical. For breeding I've seen some set ups that I think would be better than a single sump. One breeder had his breeding room set up with an airheader along the ceiling and then has airlines run down to his tanks running sponge filters. With the low bioload and eventual inhabitants it looks to work well. I actually think the sump idea would be a bit dangerous for breeding as well just for the chance to suck the fry down and through the sump.

For display you're going to be forced to put the tanks in close proximity and to have the same water conditions in all of them.

I guess it all comes back to needing to know what the purpose of the tanks is.

I believe I would go with sponge filters such as HYDRO IV with a large pump capable of supplying enough air to drive five of them. Or several small air pumps ,one for each tank. Large storage tank for aging the water and refills. Pond pump with length of hose for draining each one quickly. Or,, as mentioned have then drilled .If i had more than five tanks that would prolly be the way I'd go .

Yeah, spring for an in-line piston air pump and hook it to a PVC loop over the tanks. You can get steel, brass, or plastic airhose taps from jehmco for pretty cheap. Put in 10 taps, put a pair of sponge or box filters in each tank, and away you go. This is the set up I am planning for my fishroom with 20 tanks or so. The in-line piston pumps will drive air for up to 50 tanks (depending on size) in absolute silence, and with incredible efficiency (it only works as hard as it needs to to keep the air pressure up, so the fewer taps in the air loop, the less work it does).

The other option is to put a sump with reticulated foam under them and either drill them of fit them with overflow boxes. I visited Discus Hans' place in Baltimore this summer, and that's essentially want he has going.

I agree, if one tank get "sick" all five will get "sick".

Actually, just get a big air pump, a five-way gang valve with 2 inputs, and 5 good sized sponge or Box filters. Voila.

i just use a 1" ID pvc with taps and hoses and a big blower for my fry/growout/quarantine tanks
