Review on UPETTOOLS 1.8In 30PCS Small Ceramic Bio Media Filter for Sump Tank, Pond & Large Fish Tank by Tami Francis

I put them in the tank when I got them a few weeks ago, I even buried the bubbler under a bunch of them but my water got worse anyway. I still have to change the water and do a full cleaning every few days even though there are only about 15 small fish in a 100 gallon aquarium. My water only becomes clear on the day of the change, the next day it looks the same again. I have 2 charcoal filled cascade filters, a whole cleaning crew and I've recently started feeding my fish live tadpoles and shrimp to help with the cleaning a bit but I've had no luck. I really hoped those stupid bricks would make a difference. I've spent about $1000 on this tank in just a few months, tried everything but I still can't see my damn fish 😑
