Thanks Mark and Lindsey. I was thinking similar I was just wanting confirmation or reassurance from someone before proceeding. I’d thought of superglue but I always end in such a mess plus if I ever remove it I can with silicon and a razor. The filter sump section will have 3 compartments 150mm x 150mm x 450mm each enough for my hand to reach in. Also the baffles will be acrylic I think I’ll use Weldon number 3 or 4 on one side and silicon the other should do. 1st compartment 3 different sponges and noodles, second compartment bioballs so that a peace lily and or pothos and third compartment variable speed pump diy co2 reactor and a heater (if needed). And acrylic covers on top of the 1st and 3rd filter compartments…..
thanks again
