I could get it off if I took the metal brush in my hand and swam down there. I put a dumbell on the bottom and swam down and w one hand I held the dumb bell and with the other hand I scrubbed away. Also good for steps etc. But I recommend vaccuming after. [Also I wore goggles and earplugs MUST HAVES for the procedure I described]
Well in a way I did. I explained that acid washing removes the stains but makes the problem worse. The reason why you have algae gets worse when you try to solve it. The problem is the surface is porous enough to develop algae and that problem should be addressed to actually solve this issue.
My diamond brite plaster is only a year old after we opened the pool we realized it has many stains that won’t come off with brushing. Any suggestions?
We know our pool needs to be replastered - the plaster is chipping off (delamination?) and we have black algae stains and discoloration. All the chemicals are perfectly balanced and the water is crystal clear, but it really looks bad and can be off-putting. We've used black algae killer and scrubbed with wire brushes and have been unable to remove the stains. They've been there for the last 2 seasons, but the cost of replastering hasn't been in the budget yet. Would you say the pool is safe to swim in, even though it looks bad?
I don't think I would swim in a pool with black algae. It's actually not algae. It's a cyanobactereia which is substantially greater concern than just plant matter growth. Sounds like it is time for a new interior surface...whether you are ready or not unfortunately. At minimum a drain, treatment, chlorine scrub etc.

7 to 10 is the average. Most pool owners do not recognize when the plaster needs to be repalced (rough texture, not smooth any longer) and try to extend longer than they should
My pool pump went out and i just let it sit for a cpl months and now just drained it. The walls are stained, i am not ready to re plaster it. Would acid washing be the best solution to remove the stains?
Yes as someone who builds and plasters pools my experience is that people tend to push interior finishes WAY too far. To them it still looks more or less the same but to experienced plasterers the service life of the finish is well past due. Pool plaster wears out in less than 10 years in most cases. Poor water chemistry reduces this time. Acid washing reduces this time...so yes, when it is time to change it you need to change it. No silver bullet here.

so basically you’re not saying how to get the stains off the walls ?

how many years would you say plaster should last

So you’re an advertisement for plaster replacement and no other solution...
