View Full Version : 2 WAV pumps enough for a 400 gallon aquarium?

According to Neptune and their marketing guy - just two WAV pumps is enough to create water flow and no dead spots in a 400 gallon aquarium...

Depends on your rockwork.

An SPS system? Now way. I would say 4 at least. For an SPS system the common thought is 40x display volume which 4 will give you exactly that. However I have about 60X @100% and my display has little amount of rock. I feel I have the right amount of flow.

bif, are you saying you have the WAVs?

Two WAV can get a lot of water moving in a 400g. I have three (in my 425) and they never are over 50% - there is plenty of flow. Unlike some pumps, the WAV can move water strongly down a 10' tank - I have seen two WAV replace two MP60 in a 10' peninsula tank because they actually could reach the other end and get a gyre going.

I have 2 WAVs in a 6' 190 n while they move a fair amount of water, it's very narrow and I'm getting cyano build up in areas of low flow.

They are set to a max of 80% Maverick with 1 in 100% inverse.

I'm going to play around with placement.

I would say it depends. But 2 is the minimum. I have 2 WAVs in a 4' 120g. I have to clean every 3 months to ensure best performance. After cleaning I have both running at 40% max. After each month I have to bump up flow by 10-20%. At the 3 month mark, I have both at 100% in my 120g...until I get time to take out and run in vinegar to clean.
