I am planning to build a wet/dry over head for my 75 since I will be able to repair it next month. It will be 3 pcs of stacked plastic planter which is 16x8x6" of size with filter floss in the top layer, pot scrubbies in the middle and a submerged ceramic rings for the bottom layer. Is this a sufficient filtration for a slightly overstocked 75 gallon?
