Scrubbed is made by Rubbermaid. and the filter sucks the algae out. hate typing on my phone.
I had a bad case of hair algae less than a year ago and I blacked out my tank for 3 days by taping black trash bags on all sides. Afterwards the rocks were spotless. You mentioned that you blacked out but how did you do it? Did you just turn off the lights? Or did you cover the tank completely to prevent even ambient light from coming in?
Did total blackout the last 10 days and changing GFO weekly.
Absolutely zero dent. Algae spreading.
This thread gave me the shivers. I'm of the distinct opinion that sometimes our 'rule of thumb' advice for certain problem organisms miss the mark entirely because our 'rules of thumb' group said organisms into entirely meaningless catch-all categories like "hair algae". If you're dealing with a particularly pernicious flavour of an uncommon species of "hair algae", none of the things we recommend may work. The thing that controls this algae in nature might be some random species of some random fish/invertebrates that have never entered the hobby, and you may very well be dealing with the marine equivalent of Canada Thistle or some other noxious weed.
If you truly want this to be gone from your reefing life once and for all, and you've really tried everything everyone else has suggested, I don't see what options you have other than a complete scorched earth approach. Half measures like cleaning a few of your rocks at a time are just going to be a huge amount of time and effort for a temporary reprieve as this stuff will just re-colonize them if they go back in the infected system.Anything you can't frag off to living tissue-only will have the be considered forfeit, and you'll need to bleach your rocks, drain, bleach and dry the tank and all equipment that have ever touched the water, and start again.
If you soak your rocks in bleach for a few days, then dip them in HCL, there's pretty much zero chance any spores will survive, so I think the rocks themselves are salvageable, but to truly be rid of it you need a clean and total break.
Then need to decide how to do this. I am not sure drain and dry needed. Once fish out, why not run bleach through the system then dechlorinate well? Then re-cure rock in the tank a month or two after the bleach/acid treatment on them? I would replace all sand but not clear why the drain and dry needed if I bleach the system.
