36 weeks into running the SURF2 and I’m losing faith. For 9 weeks the GFO in the system has been removed. There are hints of success as algae starts to grow in the box but then it regresses. HELP! If anyone has had a great experience with the SURF2 please let me in on your secrets to success!
Granular Ferric Oxide (GFO) is a phosphate remover commonly used in the saltwater aquarium industry. I am installing a GFO reactor on my system to help keep down nuisance green hair algae. I picked this BRS dual GFO/carbon reactor and GFO media up from my local fish store. A single canister reactor is supposed to support up to 120 gallons so I’m hoping the dual canister will help put a dent in the 400ish gallons in my system. Like they say “an ounce of prevention is worth a pound of cure.”
