Koller Products TM1137 First Impressions

Not anymore!

In-line, out-of-tank, saltwater use. Will empty 75 gallons of mixed water to my 300 gallon aquarium in about 5 minutes. Will empty 75 gallons of mixed water to my 300 gallon aquarium in about 5 minutes. They seem to also enjoy a small water fountain and splashing in it. I do encourage the purchase of these pumps. Any pump will clog unless the fountain is kept clean. This pump is perfect for the small fountain and provides the sound of water flowing.

Koller Products TM1137 Final Thoughts

- It works!

Ordered this one and received it in one day. The video shows the pump at full throttle and can be adjusted lower. It is a definite asset to the outdoor space. And their customer service is great. We start mixing when we begin the water change. The water movement helps attract them. Highly recommend to clean the bottom of your tank if you don't have a bottom drain.
