Hey guys,
I've been sifting through the forum, and I'm having some trouble spotting any posts with filtration systems. I'm researching potential systems that I'd like to build in the future for my fish tanks, so I'd like to get some ideas of what you guys have done.

Regards
 
there are 3 ways to do it. one not like you are talking about but filters for each one such as hobs or canisters. two is a centralized sump system. all the tanks are hooked together with one big sump. you can drill the tanks or you can make your own over flows or buy them. the 3rd option is a central air system. one big air pump that powers corner/box filters sponge filters and or ugf. most people use sponge filters though.

there are some pros and cons on each system. a central sump system you can potentially over stock a tank more since there will be greater water volume. also makes water changes super easy. less worried about cycling a single tank. one down side is you have to make sure everything is QTed before hand if something gets in the system you have to treat the whole tank.

for the air driven set up a little more room to expand and contract if needed. it allows you to change the water parameters in each tank. can be cheaper to run as well. cons can be you are stuck with just the water in the tank.

there most likely other set ups but these are the most common ones i know of.
 
Is this a marine setup or freshwater?
 
I think for a SW set up you can do the centralized sump. Basically, one massive tank is the sump, and the rest are hooked to it VIA pumps and pipes. This has the plus, as Mgamer said, of increasing water volume, making WC's easier, and by removing the need to cycle each tank individually. The last bit is only if you have a cycled tank already set up and attached to the system, since the water goes through all tanks anything bad is sucked up by the LR in other tanks while one cycles. However, this only works if the water goes through each tank AND the sump before reaching the cycling tank again. The biggest downside to this is that disease spreads to all the tanks attached to the same sump. Also, if one tank leaks or breaks, all the tanks will lose water.

You can also do isolated tanks. Each tank gets its own systems. This restricts the spread of disease, but means each tank needs to be cared for individually.
