29 gallon biocube

Hello, I have had a 29 gallon biocube with 1-clown fish, 2-peppermint shrimp, some hermit crabs blue legged and 1 red legged ,some small snails my turbo's must have died, and some zoos for about 7 months now and have gotten a outbreak of hair algae. Its been a ongoing battle. I just put some bubble culerpia and some feather type culerpia in my tank. I just placed a order for algae magic, Fission Nano-Protein Skimmer , Reef Crystals salt (I make my own salt using distilled water), and chemipure elite. When the arrive I am going to scrub all the rocks that have hair algae on them, Do a water change about 10 gallons with reef crystals salt, add the algae magic, add chemipure elite bag, and add protein skimmer. I have removed all my bioballs 6 months ago and replaced them with live rock rubble. I am using aqua-pure phosphate filter pad as I removed the pad that came with my biocube because it was constantly getting clogged. I am wondering if anyone has any good/bad reviews on any of the items I am going to put into my tank especially the Fission Nano-Protein skimmer ? I have heard mixed reviews on this. I hope it works correctly. Any info will greatly be appriciated. Also I would like to change the stock pump , what would be a good replacement ? Thank You.
