If you have a severe black algae problem that you have been mitigating for years and can't get rid of can getting a very dark blue liner help to hide the black algae stains?

Answer 1

In a word ~ NO. If the algae bloom is that severe maybe a replaster is in order. Sounds like you need to be more diligent on chemistry in the pool along with proper filtration among other things. Sounds like a problem of neglect. Black algae will bore into the plaster unlike green algae. It is very difficult to get rid of especially on rough plaster. You cannot cover over it or paint over it. Oh, the dark blue liner or any liner can and will cover and hide the algae problem but you will still have the algae problem and in fact compound the problem. The algae could bore through the new liner and then where will you be - - right back in the same boat. k

Answer 2

While a dark blue liner may help mask the appearance of black algae stains in your pool, it is important to address the root cause of the algae growth. Adequate water circulation, proper chemical balance, and regular maintenance are crucial to effectively combat and prevent black algae. Consider seeking professional advice on tackling the persistent algae issue to ensure a long-term solution.
