What our Clients Say

"We have the Wave 36 Vortex settlement tank, 2 Wave pumps and love all the W Lim products. The pumps are 4 and 9 years old and still working great. Before using W Lim products, we were losing fish. We have a 14,000 gallon pond with 30 Koi and 30 Gold fish. I recommend W Lim Wave vortex settlement tanks and all of W Lim products."

“I just called about ordering a Wave II 1/2 HP pump. I currently have a Wave II from about 16 years ago and I want to make sure I get the same pump."
