Hello! This is my first time on the site.
I have a staining problem also but my problem covers 50% of the bottom of the pool. It's an 16' Intex 5000 gallon ultra frame that I have had for 4 years. I know my pool and it has always been in sync. This year I changed to Sand filter and SWG. LOVE IT! I have always had some mustard algae and have been using Wal Mart Aqua Chem Algae Eliminator Max. The algae is much less with the more powerful sand filter. I decided to go to Leslie's to see what they recommended for the algae. They gave me Copper Algaecide that they say is more powerful than Wal Mart brand. They recommended 2 oz and I put just that. The next morning I woke up to A BLACK BOTTOM POOL!!
When I called them they had absolutely no clue what I was talking about. So I searched the internet for days and finally found a post about copper staining. I will say that I have a metal ladder that the salt water rusted and I didn't take it out soon enough. So it deposited some rust in the water that gathered on the bottom. I was able to vacuum it out but I think it added to my black bottom issue.
I went to Leslie's to get chlorine neutralizer, stain remover and Metal Out. I have completed step 1, chlorine neutralizing, and then put 1 dose of stain remover in. NOTHING happened so I put a second dose in. It is now staring to lighten up. I tried brushing the stains and it removed a minute amount, really just lightened it a little. The parts of the bottom lightly affected are really brightening up.
Here are my questions: How long will this take? Should I put yet another dose in? How much is too much and will damage the liner? Do I wait for the stains to completely disappear before adding the Metal Out product?
Any help would be GREATLY appreciated as Leslie's is NO HELP.
