Missed a couple of water changes.

Life got busy, my wife ended up in the hospital in a diabitic coma for a few days and I missed a few water changes on my 90 reef and now am fighting long hair algae. I have never had it. Usually I do a 25%-40% water change every 2 weeks and for 2 yrs all has been good. I have taken some of it out by hand, took a tooth brush in a bucket of saltwater and brushed some of it off the rocks.. added some more snails.. Any fish i should add that might help? Thinking a lawnmower blennie or a starry blennie. I am going to get a Diamond Gobby to get the sand moved around a bit.
