I have a 120 gal. Reef tank in the making. There is plenty of current in the
tank with 4 maxijet 1200's and a 30" spreader bar in the return line with a
1/4"
hole drilled every inch. After feeding, especially when adding Zoecon,
millions of tiny bubbles pour from the return and the power heads. My
assumption is that oil in the food is causing this? It looks like snow in
the tank, but the bubbles rise to the top and disappear. Is this harmful to
fish or corals? Is there anything I can do to stop this from happening? Any
help will be appreciated. thank you.
