Are you using the pleated cartridge?
Im not sure, but it appears that I might. I googled it and it looks similar to what I am using. Is this the cause?Are you using the pleated cartridge?
I am going to be running it on a 20 gallon tank and it will be the only filter running on this tank. Is there a particular one you would advise picking up.Also, as they get older they just don't clean up as well by just rinsing them. I soak them in a bleach/water solution and it helps clean them so they'll run longer the next time. Just need to treat them with de-chlor or let it sit for a couple of days after. I keep an extra on hand. But I just use it on occasion to clear the tank if I've made a mess.
EDIT.... you can run the basket with the blue sleeve but it won't work the same (won't get the super fine stuff out).
Ya I am going to switch it from my larger tank to a 20g tank that I am setting up. My question is what should I replace the pleated cartridge with? I bought it used and it didnt come with anything else. I googled it but all I see for sale is the pleated cartridge.Not sure what you're asking. Are you going to use the HOT 250 on the 20g?
