Review on 🐠 GKM24W Internal UV Aquarium Filter for Tanks up to 120 Gallons, Black by Rachel Lopez

I really wanted something outside the pool so as not to take up valuable space. I was also reluctant to complicate my installation with a built-in system, so I gave the CKM24W a try. It was a good balance of cost, simplicity, and promised results. The attached photos (days 1 to 4, spaced 24 hours apart) show how quickly this cleared my water. I've adjusted lighting, temperature, and feeding to keep everything under control; but without the GKM24W I would be lost. This product worked very well for my 75 gallon freshwater tank which also has an external canister filter and it didn't suck in any newly hatched fry!
