How to Treat and Remove Scale on Your Pool - Beautec by Easy Care

YouTube Video Index -- A list of all of my videos: http://poolmandave.blogspot.com/2014/...

In this video I show you how to treat a pool that has developed some scaling on the walls. Usually it is just on the walls of the pool but it could also effect the bottom. It is a process that involves lowering the Alkalinity down to 80 ppm (it is okay if it gets as low as 60 ppm for a brief time) and keeping your pH between 7.2-7.6. You then will need to brush your pool with a steel algae brush and possibly lightly sand it with 80-100 grit Sandpaper.

The key to the whole treatment is using one or two bottles of Beautec by Easy Care. This chemical is a descaling agent that will loosen the scale off the pool wall so that brushing or sanding it will remove it. I have used Beautec in several pools with very good results.

Of course if the pH is at 8.2 and the alkalinity is at 120 ppm the process will not be as successful. So along with using Beautec you must keep the pH and Alkalinity low.

The first pool in the video is a new start up that had flow issues. The new filter got dirt in it from the a construction problem and the pool was not circulating well for two weeks after it was filled with water. This caused the scaling to develop after the first month. The scaling was severe. I successfully treated the pool and after six months the plaster is as smooth as silk. Thankfully.

The other pool was remodeled about eight months ago and for some reason there is scale on the north side of the pool. The south side is perfectly smooth. I suspect the fill water is extremely hard since the autofill is on the north side of the pool. Whatever the reason I am currently treating the pool and the scale is disappearing.

In the video I go over a few things that you might not know so I have included links to various videos to help you.:

You need to be somewhat familiar with basic pool chemistry. You can do the pH test with either the five in one kit, a Taylor Test Kit or the Test Strips. The first two also has the acid demand test but the Test Strips do not allow you to do that. Basically the acid demand test will help you calculate how much acid to add to lower the pH to 7.2 in your size pool. To calculate your pool volume (how many gallons):    • Pool Volume (long version)  

If your Alkalinity gets too low you can raise it without raising the pH significantly by adding Sodium Bicarbonate or Baking Soda. Contrary to what Baking soda advertises it will only raise your pH slightly but the Alkalinity higher.

I mention several times in the video keeping the alkalinity at or near 80 ppm and the pH at 7.2 because that will help control the scale and allow the Beautec to loosen it from the pool surface.

A few things to note. A new pool will sometimes have a huge acid demand as the plaster is curing for the first month or so - sometimes longer. So don't be afriad to be dumping tons of acid in it to keep the pH low. If your pool has a salt system I recommend not using it for the first 6 months in a new or remodeled pool. It will cause the pH to ride too high while the plaster is curing. I would also suggest keeping the maintenance level of Beautec in your pool to prevent the scale from coming back. After the scale is eliminated it is fine for the Alkalinity to go up to the normal range of 90 ppm to 120 ppm in a plaster pool. The pH can also be kept at 7.4 7.6 without fear of the scale returning.

You can also use Beautec when you just fill your pool after a remodel, new construction or if it was drained for some reason. Add one or two bottles to prevent scaling. It can also be added to prevent calcium build-up on your salt water cell.
