Dealing with scale problem

[PoolDoc]

Maybe not as fast as I'd like, but as I keep at it and follow your advice on chlorine, oh, etc, the algae is slowly going away.

Then, you're losing.

You are wasting chlorine, wasting time, wasting effort, and wasting money.

Kill it quickly, as Watermom told you several days ago:

If you stop adding chlorine, your algae will take over even more than it already is! You don't want that. You need to be adding chlorine daily up to shock levels! Don't stop and let the algae get even worse!

My biggest concern is the scale.

Maybe, but you can't deal with the scale, till the algae is gone.

I'd rather leave covering the pool as an absolute last resort. To keep my cover on means having the brass bolts raised. Too great a risk of someone stubbing a toe.

You raised the issue of the cost of dealing with the algae. If cost is not that much of an issue, leave the cover off. If it is, cover it.

I wasn't suggesting that you swim with the cover one. I was suggesting that you forgo swimming till you've solved your algae problem.

I'm still curious what a yellow color result when the hardness indicator is used means with the HTH kit.

The HTH 6-way has a different hardness test then the K2006. Here are the instructions: http://pool9.net/hth-6way/
