I have a 150 gallon tank with a 9" clown knife,8"arowana,5" shovel nose catfish,3" Parrot fish,2 - 3"NTT's, 4" Pleco, 4"Striped Rapeal. I have an chance to buy a new aquaclear 300 pro series wet dry fplter for $175.00. Need advise on whether it is worth the money and will the filter handle the load and this size tank. I am running a Ehiem 2217 canister filter and a aquaclear 110 filter presently.
