Problem with ATO in Fluval 13.5g

[H.E. Pennypacker]

Hello,
I have a Etsy 3D printed chamber 1 media basket which runs filter floss up top and carbon right below it. I have a heater in chamber 2. The problem I run into is as the filter floss gets dirty the ATO does not fill up, so when I change the filter floss in the morning the chamber 3 level drops significantly and the ATO kicks in. I'm wondering if I should just switch to an inTank media basket or a nano protein skimmer in chamber 1.... any recommendations?
I have the bypass plug installed as well.

Is this the fluval flex 57L? If so I run skimmer in chamber 1, media (carbon, sponge and bio stuff) in 2nd and my return and heater in 3rd

Also got a uv steraliser in chamber 3....still not sure how it fits on there

I think ISeaLive carries a fleece roller for your tank. I just picked one up for my WB 20 and couldn’t be happier with it

Oh, I did actually move all this over from an evo13, same setup just on the side basically same volume but shape fits my little space better

Try putting the Ato. In chamber 3; turning it off during maintenance. I put my Ato in an external refugium. Check out my build thread.

Update for everyone, I ended up buying the inTank media basket as it was same day delivery on Amazon and problem solved! the 3DOcean one I believe was somehow trapping air which was causing fluctuations when I changed the filter floss. My salinity has been rock now, the ATO working perfect, and have seen a decent increase in nutrient intake.
