Hello I just wanted to post this to say how impressed I am with this scrubber. Before buying it I had read a lot of reviews that were mixed which did not help make my decision in the end I went with Clearwater cause it was little cheaper then the other I was looking at. Over all I am very happy and actually impressed with the results I have received. I installed the scrubber on june 25 brand new and started light cycle at 24 hours a day as directions stated. Within 4 days started to see algae growth so turned lights back to 18 hours a day. Also have apex flow sensor installed noting manufacture recommend 600 gph I am pushing only 265 gph threw the scrubber. So now today it’s only been 14 days since new and already need to scrape algae off because screen is completely full and water is coming from emergency drain from so much algae clogging main drain. I’m like wow. Anyways just wanted to share and say these things work to grow algae. Now as far as reducing phosphates or nitrates I have not seen a huge drop in them yet. I’ll be testing daily and will report if anything great happens.
