- Avast Marine
So far this is awesome and has solved my high phosphate levels literally overnight! For years I battled high phosphorus levels (above 1.00) and have tried everything from using the messy cheato (which always clog my pumps), to phos RX which was just a temporary band-aid. Almost every piece of equipment I own is a product from Avast Marine. Keep up the GREAT work Justin & Dan!!
Very Good! Easy to get started and the quality and effectiveness is evident.. Rinsing lid is also awesome.
