It should be ok, I would do a water every 2 weeks maybe even more.

Quick question on my flowerhorn, my canister filter started leaking and I have a sponge filter rated for 50gallon tank. Is sponge filter enough for my flowerhorn tank?

breeders use two sponge filters for a 30gallon tank. wouldnt hurt to put more filters. i would put more just to be safe. even me myself use a top filter with 2 sponge filters in my 30g for grooming.
