I don't know how the $ would turn out in this idea but you can crunch some numbers and check it out. If you pick up a rubbermaid container or something similar and cheap you can use that as a common pool for your tanks if you plumb them together. PVC
is cheap and then you could buy one nice filter and put it in that tank.
Couple advantages to this that might be worth considering
-one filter will make maintenance considerably easier
-a common water pool helps to keep your water parameters more stable
- extra tank can be used to house other common equipment like heaters and media reactors.
i am not a fan of UGF
but people have used them for years and lots of people still use them. though the best way to use them would as a reverse under ground filter. doing this it pushes the water down though the pipes and up though the substrate. this helps turn the whole gravel bed into a bio filter. as for clogging like anything if you dont maintain it it wont work right. just like if you ran a canister and never clean it finally it will stop pumping any water at all.

I didnt quite understand what you were saying PAT8YOU but it sounded good. lol. can you send me an article or tell me more on how that works?
Also! thanks for tellin me to stay away from undergravel filters guys! I had my suspicions as to their usefulness....
dont take this personally but why are you doing this? you dont seem to know about keeping fish. its not as easy as tossing some fish in breeding and netting out fry. i see several holes in your idea. like the inch per gallon is a myth it doesnt work in most all cases..... also expecting to keep 4-5 inch fish in a 30 gallon tank.... do you know about the water they come from? do you know how to take care of the fry? diet of the fish?
while it might seem like a noble idea.... though when dealing with endangered fish personally feel its better to leave things to people who know what they are doing. or at least learn the basics before working with endangered fish.
you could just use a decent amount of Live rock for filtration
i believe these are fw
though i could be wrong.
