Well installed the wp25. My first impression was its a good size. It's powerful. Customizable. Not sure how to compare a I do not have an mo10 or any other wave maker but I definitely would recommend. And the price is very doable for anyone in the hobby who wants to get the random flow ms as natural as you can.... In a four foot box.
Tennis ball size I would say
You can see it next to the koralia evo 1050. Smaller
Controller is fine for what I know of controllers
Just so you don't think I have nothing in my tank. This is the right side.
Do need to finish off the rock work on the left.
