Review on Seachem PhosGuard 1L: Highly Effective Phosphate Remover for Crystal Clear Water by Sophie Martines

Bought this to reduce PO4 in my 150 gallon saltwater aquarium. Made my own little reactor and only added 2/3 of what was recommended. I made sure to rinse it well and even after 4 times there was some haze. Setting the flow so the product gets moving but doesn't freak out required some tweaking to find the sweet spot. Note that heavy motion causes more haze, but I cleared things up by adding a cheap mechanical filter for a few hours. After a few days I see a very clear difference between the ugly kelp and the green algae. After 5 days my PO4 is not being tracked and the algae die off is beyond my expectations. My only occupants are a small CuC who seems to be doing fine as I continue the cycle. The only reason I gave 4 stars was that it is difficult to rinse out completely to avoid cloudiness, other than that I am very satisfied.
