what filteration do i need for a 210g 7x2x2 . 1x19" arowana i might make it a planted tank or add 2 rays

not sure about you but i'm not keeping tetras in in my 210!!! so the more filtration the better... having a big tank and keeping little fish is like having a fishing boat and not fishing, it just doesn't make sense!!Merbeast;1273802; said:It depends. Planted tanks need much less filtration. Big, messy fish need more filtration. What you put in the tank determines the level of filtration necessary more than the size of the tank does.

......my only problem is tiny particles...
dead spots!!!!
Why tap water? You are wiping out that "extra" bacteria. Why not a bucket of tank water to preserve it?Bderick67;1275048; said:Well this is what I run on my 180g with two 23-25" silver aros, 15" tiretrack eel, 8" polleni and a dozen other 4-6" fish. Two AC110s (rinse sponges with hot tap water weekly) and a xp3 with I clean about evey two months. Along with weekly 50% water changes, the water is clear and params are always perfect.
