Red fury stuff growing on Chaetomorpha!

Hey all....

Hoping you can help me ID this red stuff growing allover my Chaetomorpha in the refugium!

It does not look like a Cyonobacteria!

WOW, i knew it was something exotic, but never knew it was that invasive!

Just did some research and nothing came up! Do you have any info on that Cotton thing, like the cause and solution?

The same for hair algae or other high nutrient nuisance algae. Lower Po4 by reduced feeding, water changes, GFO. Do you have any other algae/green stuff in your display? green covered glass every 2 days?

If its localized just in the fuge there is a good chance its going to stay there, but just realize you have a small problem and should monitor/fix it ontop of what your refugium is doing.

Also, i see some bryopsis or hair algae in the corner as well. If its bryopsis I would start removing it religiously. =0)

I do have to clean the glass in my main every 2-3 days, it's getting green, but my back wall glass never gets bushy! My PO4 reads 0, NO3 reads 0 (according to API test kits)! That red stuff were only in my refugium, growing only on chaetomorpha which i totally removed and left a small clean chunk to grow! The first two pictures show that red and green algae in the corner, that is the only algae spot in my whole system! Besides the green glass every 2-3 days, there's now green/red growth in my main!

Heres the age old statement here on MR- Even if you have 0 phosphates you have phosphates. Test kits are useless to detect phosphates. If you have readings register on your test kit- you have a large amount. The only way to truly check for phosphates taht are at a low level is with either a hanna photometer which are available but a little expensive or lab grade test kits, which you cant find on the market. Run GFO if you dont already and change it often.
