Herbie drain is a pain

[Potatohead]

Does anyone else have to constantly fiddle with their drain? Mine will be set and level for 2 - 3 days and then over the course of like 12 hours it will start rising in the overflow. I thought it was my filter socks clogging but when it started rising I pulled the socks right out and it didn't go back down (mind you, I didn't leave it for hours like maybe I should have). Starting to wish I went with a beananimal style . I backed off the valve like 1/100 of a turn and started the level in the overflow basically as low as I can, so we'll see if that helps, but I'm not super hopeful. Anyone figure out a solution?

Thanks
