The scale is calcium carbonate from having too high a combination of pH, Total Alkalinity (TA) and Calcium Hardness (CH). As Pooltech32 noted,...

You can add as much acid as the acid demand test says you can. This will vary depending on your starting and target pH and your starting TA. As your...

Thanks guys. I vacuumed my pool and drained then filled about 1/3 of my pool. Hopefully my TDS numbers will be down. I'm sure my pH and alkalinity...

If you aren't registering any Free Chlorine (FC) then either the saltwater chlorine generator (SWG) is broken or not turned on or you have something...

If the Nature2 cartridges are adding enough copper to the pool to kill algae, then they will be effective, but that level of copper is also enough to...

I personally would get my Calcium up to about 150ppm, it will rise a little bit but not that much and you want to protect your plaster.

Hmmm...

this alkanility is something quite new for me and could explain why I have to add so much darn acid all the time :(

I'll try to have the...

My pool test kit told me TA was above 200ppm. I used 4 bottles of 7 LB hth pH minus to lowing total alkanility. However, now TA is 140ppm, pH is...

Many thanks - will give the aeration a go and see what happens.

I appreciate the help! 8)

Are you sure this is a leak and not evaporation? Do you live in a hot or dry climate? If my math is correct the pool is losing a little under an inch...

I keep my pools quite low in chlorine during the winter months, around 2ppm should be fine. I actually replace the salt cells for the winter with a...

You can learn how to defeat algae (IF you have algae) by reading this article in the Pool School, but you should really get a good test kit since...

SWG pools tend to rise in pH due to a combination of factors including greater aeration of the water and some outgassing of chlorine gas that doesn't...

I suggest you read some of what is in the Pool School to educate yourself on what product goes with each parameter.

In what you listed, Calcium...

Do NOT try and lower the TA using the slug or acid column method just described. Not only is it not very effective (as discussed here ), but...

So if you have a way to vacuum to waste, then you can use OMNI Liquid Floc Plus to accelerate the clearing (just follow its instructions adding the...
