Is the flow still acceptable? And are there fish in the tank?
If there is no fish in, just put the hose directly in the tank. If there are fish, than maybe you have a plastic pant pot laying around? With some effort you can use this to keep the fish out of the hose, bu tstill the water in.
With that kind of setup you would for sure not break the filters. There might be a slight loss of the combined flow.
But why so difficult and not just put both spraybars just straight next to each other in the tank? Would have the same optical effect
