Cyclop-eze looks so tiny you wouldn't think it could foul water... DUH! Of course it can. I was just surprised by how fast it happens. I was feeding my new anthias a couple scrapings of cyclop-eze a day with some mysis and MAN did it foul my water fast. I've stopped using it all together until I can figure out how much of it is sufficient to feed. Luckily they'll eat anything under the sun and I've switched them over to Formula 1, 2 & Prime Reef (which is what my main eats anyway). Just curious how you're able to use it and not cause an ammo issue
