Thats really nice! I have similar things to that also!My fluval evo 13.5 tank 11 months in. Survived bryopsis with fluconozol 2 week treatment with minimal issues. No dosing, weekly 5g water changes religiously with Red Sea reef pro salt sometimes bi weekly if the time is there. I’ve stuck to only nano fish 1-2” max with the exception of my clowns which will
Go to my FOWLR tank when/if they get too big but I certainly have a decent amount of nano fish with no issue.
I mostly have LPS and sofies with the exception of 3 SPS frags which I’ve had no issue using an AI Prime besides the fact I am very good at breaking them when I stick my hand in to place corals haha…
Minimal upgrades other than in tank media basket, power head and sicce 1.0 return pump.
