Hi,

Is there any rule of thumb for selecting a wave maker size. I have a 4 foot tank and it came with a Jebao RW20 wave maker which even on its lowest setting appears to me, being very inexperienced, to be too strong as the water circulation in the tank is hectic.

Not sure if this excessive current will affect the corals?

Yes too much flow will tear LPS but if you want SPS only flow can be much more so depends.

ecotech have a nice tool on their website for the MP range of pumps, use that to figure out how many L/hr you need and then shop around for any pump/s that can do that much.

There is a voltage regulator you can get to tone down the Jebao pumps. I have one on my wp25.
