Re-occurring ZOMBIE Algae...

[Watermom]

I would go ahead and brush the pool while the chlorine is high even though you see no algae.

And, you'll probably want to wear old swimsuits if you swim with the chlorine that high. It won't hurt you but will likely fade swimsuits.

If I understand correctly, the "safe" MA at Ace is a diluted version of regular MA. If so, your dosing will be different. Personally, not knowing if there is anything else in the "safe" MA that you might not want in your pool, I wouldn't use it.

Some 'safe' MA's have detergents or other addititives, making them NOT-safe for your pool.

Thanks everyone! I vacuumed the pool and while doing that I noticed some more algae... not much. I brushed like crazy and then went swimming later.

My birthday suit doesn't fade! LOL

Kept an eye on it all weekend, and so far the algae did not return. I will inspect closer again when I get home this afternoon, but maybe I have beat it back for now.

I need to take a look at the MA that I bought and see what is "exactly" in it. I will post here and see if it needs to get returned for regular MA.

I'd like to borate the pool ASAP. Any suggestions on how much MA to add to start bringing my TA down before doing so? Or as you said PoolDoc I really don't need to worry about it?

Re MA: check the MSDS; it's likely that will reveal whether there are problematic additives. However, the presence of even the slightest 'sudsing' or soapy bubbles in the MA solution is sufficient reason to keep it away -- far away -- from your pool.

I wouldn't worry about the TA. Just add the borax, and then add MA till your pH is normal. If you have a K2006, you can use the acid demand test to quantify how much MA is needed at any given point. However, I think the "poolcalculator.com" will also give you a useful indication. I would STRONGLY recommend that you (a) use PLAIN 31% MA and (b) never use more than 1/2 of the dose you think you need to fully correct. You can always add more later.

If you haven't already, do read the MA safe handling guide => http://pool9.net/ma/

Here's the MA that I have... http://www.certol.com/AcidMagicHome.aspx

I'm still looking for what's in it... Should I exchange this for the real stuff?

Yes. Mystery ingredients can cause very, very real problems with your pool.
