How much should I feed my fish

How many times have you read to feed what your fish will “consume in 2 to 3 minutes”.  What ???

If we did that, we would certainly over-feed and/or foul the tank.

Our fish consume a serving in 2 to 3 seconds,  not 2 to 3 minutes.

In our opinion, reef tanks are “over …” almost everything.
Over fed, over lit, over flow, over dosed, over stocked, etc.
Keep it simple.
