Get rid of Blackspot algae. Blackspot is notoriously difficult to remove due to its hard black 'shell' which doesn't scrub off easily which protects the algae underneath. However, removing it isn't as difficult as it sounds.
Winter is the perfect time to treat blackspot as the pool isn't in use and you need to increase chlorine levels higher than normal to attack the algae.
Clean your baskets and filter to allow for the most efficient water circulation and filtration.
Remove the automatic cleaner from the pool. This will increase water flow and prolong the life of your cleaner as there will be a high level of chlorine in the water that can have an adverse effect on its lifespan.
Then test the water and balance pH to 7.2- 7.6. When the pH is in this range your chlorine is the most effective. (bring us in a sample to have your water checked first)
Brush the algae with a hard brush, being careful not to damage the surface of your pool.
Super chlorinate your water with the recommended dose by one of our team. This can be done with powdered or liquid chlorine. In some instances, powdered chlorine may even be appropriate to pour directly onto the Blackspot.
Add the recommended dose of an algaecide such as BioGuard MSA or Algiguard to assist with the process.
Run your filtration system for a minimum of 24 hours and brush the pool as often as you can, ideally twice a day if possible until the Blackspot is gone.
Depending on the amount of Blackspot, this process can take longer and potentially require multiple treatments. Contact us today to discuss the best option for your pool or spa or book one of our technicians below to come to you!
