If you dont want to use airstones, then either switch on your refugium 24hrs or run a higher airflow skimmer or run your additional overflow pipe on rainbar to tinkle down for oxygen exchange

If the led cannot be mount high for light spread, I suggest you replace with T5 tubes instead. Led placed too near water surface with only project a strong light beam onto the corals and that will only burn or bleach them.

This is one of my favourite LPS (Atlantis Jaguar Acan echinata), given to me from bro kkk121. Have growth from 1 to 5 heads now. Just love the colours.

Look under siowaro thread, shared with him alot on fw convert to sw tank and easy corals, live stocks to keep.
Most important thing is to give bacteria time to build, cycle to complete and add live stocks slowly.
