Review on GKM9W Internal UV Power Head & Two Pack Replacement Sponge Combo for Maximum Filtration - 3 Items by Raquel Peterson

Amazing. Day 6 and it's *almost* crystal clear water. Personally, there is still some cloudiness, but I expect it to go away completely by day 7 or 8. Then I plan to remove it until some sign of green water rears its ugly head again. The photos speak for themselves. I'd say hip, you can get that MUCH cheaper through Chewy or other pet/fish store websites. But that only became clear to me afterwards. Oh good. Highly recommended. Cleans your water.
