It has basically been dark since Monday night but I actually wrapped it in Tinfoil at 5 am on Tuesday. So it has been dark about 60 hours now. I peeked inside the evening and it is crystal clear but I'm still afraid of it coming back... might leave it dark until tomorrow evening.
My refugium is about 3 gal and I don't have a sump. Hard to tell how fast cheato is growing because I just got new stuff to replace the stuff I killed. I have 2X9W compact flourescents over it and they are on the same light timer as my tank. This whole problem (starting with the cyano) seems to have kicked off when it started getting nice this spring, around May. Although my tank isn't that close to a window, our house recieves lots of natural light in the summer. I have shut the blinds in the living room and covered the side of the tank facing the window with heavy, dark paper.

you may want to add a timer and change your light on the refugium to opposite of the main tank

Well that's a good start! It seems that if the algae issues started when the days started to lengthen, it's likely that your tank is getting too much natural sunlight. If you can, block even more of the natural sunlight. If it comes back you may need to consider moving the tank to a better location.

The problem may be gone for now, but the conditions that caused may very well still be present.
Myka made an excellent point about your water source and I think it warrants investigation by you. I don't know what the turbidity is like in Campbell River, but I would bet there are a lot of silicates and phosphates and the like in the water... That was a pretty bad issue you had there, even with it gone I would take some time to consider why it happened and stop it before it starts again after you've potentially put more $$ into your system.

silicates and phosphates both read 0 on test kits and tap water has a tds of about 6-8ppm

the majority of tapwater will test around 100 - 200ppm. I understand that Campbell river is known for great water quality but getting 6-8 ppm is better than some RO units! you may want to have your tds meter checked and calibrated.
