Hey
@eminor
Post #602 onwards may be useful in dealing with thread algae
here. Hopefully it won’t get to this though, but you can remedy if needed.
Using glutaraldehyde can help overcome co2 distribution trouble spots in a tank if dosed daily. Not particularly keen on using glutaraldehyde as an algae treatment. Can cause tissue damage on plants, creating new problems to solve.
In agreement with
@zozo though:
A lot of setups aren’t running long enough to hit this bother. Find it interesting that locally, a few tanks suffer at the same time and annually.
Tanks running 20C and below with plants appear to be susceptible, particularly tanks with no heaters that swing in temp. On one hand you’ve got it easier with dissolved gases able to saturate the water more readily. On the other, you have slower plant metabolism. Hair/thread algae appears to have an edge under those circumstances.
As an aside, have noticed that setups closest to the doors in aquascaping shops have the highest frequency of hair algae here in the UK. Particularly in November when the temp drops proper outside.
