Hi all Liquidator users.
The "white stuff" is one of the LQ’s woes as posted, for instance here.
I called David Booker, one of the LQ’s "forefathers", to whom we were referred by Sabot in this post.
According to Booker, the white deposit is the result of the high pH of the water layer at the top of the LQ. The high pH is caused by the diffusion of ingredients from the bleach layer at the bottom (sodium hypochlorite and sodium hydroxide) which is a lot more basic than the pool water.
In order to eliminate the white deposit, the pool water should be kept at pH 7.2.
Accoring to him this is the only way. Pouring the bleach slowly will have no effect.
He said that having the pool water at pH 7.2 is fine. Any comments?
keithw mentioned here that he has no white deposit. Keithw: if you read this, what is your pH?
A week ago I changed my "outlet" tubing to Tygon Ultra Chemical Resistant 2075, because the original vinyl tubing had gotten all white. I assumed it may have happened because vinyl can't resist high bleach level. The flow meter was also white. I was able to get rid of the white stuff in the flow meter by acid wash but the vinyl tubing couldn't be cleaned.
Now the Tygon tubing got white just as the vinyl did, however, after a week's use, the flow meter is clean. As Booker said - it doesn't matter what the tubing is made of. It's still unknown why the flow meter has no deposit.
Cruzmisl : you won the bet! PM me about getting your beer.
Kudos to Sabot for his detailed posts and the link to Booker.
