Increased water flow

[los.tejanos83]

I recently replaced a dual loc-line return fitting (from dual overflow boxes) with "Flow Accelerator" loc-lines. It definitely increased water circulation but exponentially added lots of fine bubbles to the water, which i heard is a bad thing for corals.:mad:

The reviews gave it high praise, but i give it :thumbs_down::thumbs_down::thumbs_down: down.
