I have 2-1" seas swirls. I'm in the process of building a custom waterbox and the euro bracing is very large. It would put the output of the sea swirls about 5-6 inches towards the center of the tank. Is there something I'm missing? Are people having holes drilled in the euro brace for this? My original plan was to mount them facing the corals from the front with a couple of rfg's. Each swirl would cover half the tank. Any ideas?
