I have a Fluval 13.5 Evo. I recently upgraded my chambers. I added a In Tank chamber basket to Chamber 1 and 2. In chamber 1 I have filter floss, chemi pure blue and bio balls. In chamber 2 I had modified refugium with Chaeto in it. I had the stock pump with the tank which was fine but I felt it didn’t have enough flow so I upgraded to a Eheim 1000. Originally for the first week on full power I was having no problem but then after the week the third chamber has little to no water in it to make the pump work effectively. I then lowered the output to about 3/4. It was working fine and now I am having a similar problem where the third chamber is just not filling up fast enough and the pump is shooting air bubbles out into the tank. Also because of this my heater is now in the main display instead of in the third chamber. I am looking for any help or advice here because I am getting very frustrated. As my set up sits right now. Chamber 1 filter floss, chemi blue elite then bio balls on bottom. Second chamber at the bottom of the In Chamber basket is sea lettuce. Attached is pictures of each chamber. So basically I need help with my whole In chamber setup and filter so any suggestions would be greatly appreciated. I may just put the stock pump back and use a power head. Thanks for any advice or help.
