I am having red slime algae problems too. My tank is almost covered and there are bubbles trapped under the algae. We bought new fancy lights for the tank and ever since the tank cycled again. We bought a huge clean up crew to add to our crew we had, but none of them seem to be eating the slime. We do feed the fish every day, which seems to be a problem by the looks of things. Not really sure what else to do?
