That looks more like red slime algae (or cyanobacteria) to me, it will continue to grow and turn into these sheets of slimey stuff and cover everything. Do a search on cyanobacteria or red slime algae and you will pull up a ton of posts but here are my suggestions.
1. if you have not changed your light bulbs then it is probably time, I think VHO's should be changed at least yearly.
2. increase flow in tank, cyano will not grow where there is good water flow
3. I would really recommend using RO water, tap has so many bad things that just feed types of algae.
4. Test for Ammonia, Nitrite, Nitrate and Phosphate. This will help tell you where some problems might be.
5. You should not feed more than every other day.
6. Start fixing problem right away, by doing water changes and sucking as much of the stuff out of your tank as possible.
Cyano is actually a type of bacteria, but it feeds off of the nutrients in the water, I suppose it is possible that you some how introduced it with the addition of your clean up crew.
