Hello,

I have a 75 gallon tank(48L x 18D x20H) with a built wet/dry. I like to replace the 2 mj1200 because there are always sands and some brown algea on the LR no matter were I place the mjs.

I would to get more circulation flow where there no dead spots in the tank.

I was looking at getting 2 hydor koralia 3 put on both ends with 1 hydor koralia 1 in the middle of the tank or 2 tunze nano 6025 instead since they have strong flow.

What do you think which is best?

Thanks,

KC

Sounds good to me. I wouldn't bother with the tunze nano stream. The flow from the 6025 wouldn't even effect the tank much at all. I have one and the flow isn't too strong and can only be noticed if within 8'' from the pump.
