I'm losing my floor racks all they do is allow for stuff to accumulate under them. Going tiled on bottom and stepping up back with racks for shrooms and other corals that want MOAR lamp. Maybe even hanging rack on back idk. Its too easy to clean tiles and bare bottom tubs with simple half inch hose once dialed and stuffs dont want to grow anyway. Trying to get away from plastic it seems to take alot longer to establish biofilm and allow for algae to grow on as well.
I dont think your racks are raised enough either way you may be better off setting them on floor it will be easier to clean the squares with siphon hose.
