Thanks for compliments. I have noticed a great colour difference in corals since starting nopox dosing. Been about a month now and everything is thriving except the algae yippee. Lol. Some one private messages me and said we had all our colors wrong and shouldn't put orange & green together & how tank looked really messy. As we are so new at this I took it to heart and thought we had stuffed up badly. Thanks I feel better now lol. I think it should just be what u like anyway we all have different ideas & tastes. Each to their own.
