Yep mine swims against the top euro bracing, dropping suddenly only to go back up tp make waves. Idk what I'd do if this tank was glass, because I'm sure she puts some force into it. I wouldn't worry, probably just getting more comfortable
Thanks for tge awesome responses everyone. It definetly made me more comfortable, i did chevk pH again and it was a bit low but i'm using RODI so i suppose thats normal. Buffered with a teensy bit of marine dkh buffer. Gotta replace some carbonates!
I don't think it's necessary, between the surface agitation and the trickle of the wetdry my o2 levels should be more than sufficient, besides i hate the look.
