Hello! I just ordered 2 bottles of FerriTabs. I’ve been battling iron stains in my pool for 3 years so I’m really hoping they will help. I plan to do an ascorbic acid treatment before adding the FerriTabs. I have a 20,000 gallon pool and I’m a little confused about how many FerriTabs I should use. I read that one FerriTab treats about 3,000 gallons so I assume that means that I would need about 7 in my skimmer basket after the ascorbic acid treatment. However, I also read on your website where you said you usually add 1-3 at a time. Can you please clarify? I don’t want to use too little or too many. Attached is a photo of my pool. You can see the iron staining and also the blue-green water due to the iron.
Thanks!
Yes after you do the ascorbic acid then add 3 tablets, circulate 24-48 hours, backwash or clean the filter and repeat until your backwash water is running clear and you don’t see the discoloration. Then just add one every time you top the water off in the pool for prevention…they are wonderful!
