Help! I couldn’t keep my old filter in my tank because it stopped working. I bought a Fluval U1 filter and it’s made the water cloudy, will this kill the fish?
It’s a good idea, but the cartridges are much bigger in the CF1 width wise and can’t be taken apart to be used in the U1.Looking at photos of the two filters, there are a cartridge and green pad in the CF1 while the U1 has a single foam? Can the cartridge and green pad be held against each side of the U1 foam and then slid together into the filter?
Will give it a go cheers, can I not just squeeze the cartridges directly into the water and wait for the new filter to clear the water?Do the cartridges contain carbon? If it does, cut it open and throw away the carbon. Cut the bag part off the frame and just squeeze that in the new filter. It doesn't mater if you have to cut it into pieces as long as you get as much in as possible.
