Hey guys i just got a 240 fish tank basicly for free, im a UW Stout Engineering student and i did some solidworks design for a guy and in return he is giving me his 240 gallon tank, not sure if it comes with filters and stuff yet but, Im planning on getting two rays to put into it, what would you guys suggest for a filter set up, there is two holes on the bottem for an under gravel filter set up... but i dont know much about filtration so any help would be greatful
 
the holes in the bottom can be used for overflows, where are they located? at the back of the aquarium? under gravel filters IMHO are outdated, plenty of people use them but they pose significant maintenance issues, reverse under gravel filters appeal to me but i have heard mixed reports.

filtration will depend on what you want to keep, and the type of set up you have.

if you want a planted tank, you will want either to go with multiple canister filters (overflow pipes can be made to work with canister filters, i know i did it) or do a low tech (soil under gravel), heavily planted tank I have heard of at least 3 people doing these tanks with only power heads, no traditional filtration. if you are interested in one of these set ups get this book ECOLOGY of the PLANTED AQUARIUM, by Diana Walstad.

if you want a fish only set up, I would build a wet/dry filter, I built one for my 125 gal for about $60.00, i had a ton of bio-balls, but i have read that pot scrubbies have more surface are, per sq inch.

salt water is a different ball game all together.

google the following for more info:

nitrogen cycle
wet/dry filters


I started off in the aquarium hobby pretty much like you did, a guy at a local science museum gave me a busted, 150+ gal tank and i fixed it. I had no idea what i was doing, that was almost 10 years ago. It's a great hobby, this forum is a wealth of info.
 
for stingrays since the tank is drilled a large wet dry is your best bet

a tank that big, go with a giant reef tank, that pwns any freshwater

freshwater monsters are better than sw imo.
build yourself a big wet/dry, theyre cheap, easy to build and maintain, and will work the best especially for rays.
