So this is been a week from hell. My fx5 on my 125 has been acting up like crazy and seems to be sucking air into it and making a lot of noise. As a result I have been up late or getting up really early to work on the filter or do WC to make sure water stays great. This really won't be an issue if I didn't have to work as well. So I have had a enough and think I want to replace the filter. I have to AC 110s on the tank and just put on a third (had one sitting around for a rainy day). The tank is heavily stocked with mostly mixed silver dollar school and some other fish. I want to add a filstar xp4. I know everyone isn't crazy about their circulation abilities, but I have five other filstars running for years with no issues. Do you think with the AC and filstar it would be enough? I am going away in 1.5 weeks and will have to make the purchase soon.
