I KEEP GETTING TOLD THAT MY MARINELAND MAGNUM 350 CANISTER FILTER IS NOT ENOUGHT FOR MY 75 GALLON TANK WHAT ELSE DO I NEED WOULD A C SERIES MARINELAND CANISTER FILTER WORK HOW BIG OF ONE SHOULD I GET SOMEONE PLEASE HELP ME LOL I WANT TO USE IT WITH MY MAGNUM 350 I CURRENTLY HAVE

i just read a little on thse types of filter and people say that they are only really good as a second filter on a tank and work well with a fluvel 405.

i would strongley sugest getting another filter like the fluvel 405 or one of the same spec:)

i hvae just bought a fluvel 405 and its great.

forgot to add, i run a fluvel 405 and a built in filter on my tank. and my tank is only 55gallons

i think every one on this site would reccomend useing 2 filters under normall sircumsances..
excuse my spelling:)

what do they cost and do you think this will help solve my issues with water bcuz i just cant understand the fish are so small in a big tank

i just bought mine for £100 and that comes with every thing you need.

personally i would go with 2 of these on that size tank with oscars in but im 99% sure that with a 405 added on there with your current filter you will do just fine:)

the list of filter that can be used is a long one. for hob filters aquaclear make in my opinion the best by far. for canisters fluval and eheim are reknown for there quality and dependability. it all depens on your pocketbook when it comes to filters. as a rule of thumb for any large cichlid fro hobs you should have 10 times your tank volume in gallons per hour flow, for canisters 4 times tank volume and sumps 3-4 times tank volume. on my oscar tank i have 3 aquaclear 110 (each rated at 500 gph) a fluval 404(rated at 350 gph) and a 40 gallon sump(pumping 950 gph).that works out to 2800 gallons per hour in theory and its on a 190 gallon tank. one thing to remember is that you can never have too much filtration with oscars or too big a tank

if you are looking for a relatively inexpensive canister you can check out the rena xp3. they are solid little filters that are in my opinion underrated
