ok well i have 2 emp 400 and a fluval 304 i no its enough for 5 reds in my 75 but that will keep the tank pretty freiken clean right

I dont know how many GPH each of those filters flows, but if they run about 6-10 times the volume of the tank, I'd say yes, thats enough.

I would say yes, its 9x filtration. Tho getting another one wouldnt hurt, the Ps like the current and over filtration is a good thing--sometimes.

I have an emp4 a fluval 4 and an ac3000 for current. So having two emp4s and a fluval 3 should be fine, may want a powerhead for current where your ps can get a little workout
