Pool RX

[Miamipool]

Rented my house for a year as we were overseas. I hired a reputable pool maintenance company to take care of the pool.

We just moved back in and I found a pool RX thingy in my skimmer. Didn’t know what it was but the company put it there in July to battle black algae in the grout.
The pool looks great and the pool RX is removed. I usually have to SLAM the pool during the Miami winter to control the algae in the shady part of the pool.

Here’s where I finally get to the point …
Should I avoid doing a slam if needed because of the copper introduced from pool RX.

Should I avoid doing a slam if needed because of the copper introduced from pool RX.

No. The first priority is to eliminate algae.

After you slam, then you can deal with the copper.

To confirm you need to slam, so an OCLT. Link-->Overnight Chlorine Loss Test
If you fail, you slam. Link-->SLAM Process

Can you still see any black algae?

Maybe get a metals test at your local pool store.

If you maintain the pool to TFP recommended levels, you should never need to do the SLAM Process.
Keep FC near or just above high end of target range for your CYA. FC/CYA Levels

What test kit are you using?

No algae or issues as of now. Stabilizer was 10-20 upon my return with a high FC but zero CC.
It’s all setup now and everything looks good.
I use a Taylor 2006, and know where I need to be. I don’t have a pool service and sometimes have to go out of town for business, so water chems go sideways once in a while.

I’ve had black algae in the tile grout on the steps in the past.
It usually comes back in the winter just in the grout in the same spots. It’s minimal and I understand I’ve probably never really killed the roots of it completely.
I was just worried if I have to do a SLAM would that cause the copper which I assume is in solution at this point to precipitate out and stain my plaster. I’m having zero issues right now.

I see the other responder’s point. If I end up having to SLAM then I have to do it and deal with the copper after. Guess that will keep me on a regular testing schedule this winter

What is your fresh water situation?

Do a No Drain Water Exchange and replace the copper water with fresh water. Read Draining - Further Reading

Miami city water.

Then do a water exchange and dump the copper out.
