I have a 20gal with 2 Percula Clowns and a choc chip star. I want to introduce a bubble top to the tank. What hardware do I need on the tank. I currently have a power filter (with only bioballs no filter cartridges) and a power head for water current and a coralife 65w light. Do I need a protien skimmer for that small of a tank? What do I need to know about the water, testing, chemicals etc? The tank has been established for about
2 1/2 years and have not lost a fish in about 2 years.
Thanks
