I have been using Aqua forest reef products for a long time. I went the KZ zeovit route for about 2 years and got ok results in my mixed reef tank. Switched to Aquaforest products and I'm constantly having to trade off my frags to local salt water stores because my tank is growing so fast. I want to win the AF Oceanguard tank so I can start from scratch with a new tank only using AF products and see the results. The new tank is nicer looking than my present aquarium.
