As a few of you may know, my tank has had a pretty bad algae outbreak. I used waterchanges at first and when i saw no improvement i decided to try a new product out called algae fix marine. Its a great product made by Aquarium Pharmaceuticals. It works fabulous. Within a month of use i have seen a huge amout of algae reduction. Now for the bad part. It tries to take away the amout of food or waste that can be used by the algae to help in its growth process. Now what ive noticed is that it also effects the copeopods in my tank. My Green Mandarin Dragonet just died recently, not from not getting enough to eat, but from the malnutritioned pods that he was eating. He wasn't fat but he wasn't skinny either. All of my water params are perfect... This was just my conclusion... Please let me know if you have any other suggestions.
