Air bubbles in tank

[Jerry]

I have a 120 gal. Reef tank in the making. There is plenty of current in the
tank with 4 maxijets 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.

What is happening is the surface tension of the water has shifted. Turn off
your skimmer and the spray bar pump during the feedings, and restart them about
one hour later.

Just don't forget to turn them back on!

I use an automatic feeder and a simple electrical timer on the protein
skimmer (the rotating ones with press down tabs) which works well. The
feeder operates at the same time daily and is handy when we're away for
awhile.

We're off to South Africa for 3 weeks next Friday, and although the
'out-laws' will be staying here for the duration, at least I'll be
comfortable in the knowledge that the fish are not being overfed by good
intentioned relatives.

The electrical timer helps with (not) forgeting to switch everything back
on.
