Help Please With Slimy Water!

by Haley
(Jennings, Louisiana, USA)

I have a pool and on today I was about to clean out the pool before I swim.


I look down at the ladder and there are these things attached to it that look like fat worms. You can see through them.

When I picked the ladder up, whatever is on it, clung together and looked like slime. Not knowing what it was, I put the ladder back in the pool and it looked like little worms again.

What is it? Can you help please??? ASAP!!!!!!




Thanks for the question Haley

First, I'd like to have your complete chemical readings:

Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, and Metals (iron and copper). It makes troubleshooting much easier and the process of clearing up your pool will go much faster. You can get this done at your local pool store.

Without these numbers I'm just guessing at what the problem is.

Get back to me with the chemical numbers and I'm sure I can help.

Most of the time when these things happen, it's a chemical issue. Things are out of balance and need to be brought back into line.

When I get the actual numbers and chemical readings I can give you a course of action to take to clear up your pool.

To post a reply, or if you have a similar question, you can see your post on the Q&A page in the "Algae/Green Pool Water" category.

Brown Algae To Swimming Pool Wall
by: Tony Randall (Pattaya Thailand)

I recently had my entire swimming pool refurbished. The reason the pool was refurbished was because I found that the pool was leaking in several places i.e. through jet inlets, old grouting joints and leaking skimmer outlet.

The refurbishment included new grouting, some patches of new tiling to walls and new outlets. The pool water system was changed from chlorine based to a salt water pool.

Recently we have noticed that a small section of the pool has brown algae starting to appear? We have tried scrubbing the area and treating the water but this has had no effect to date.

Your advice will be greatly appreciated.

Regards

Tony Randall

Next is you need to determine if it's brown algae or some kind of staining. You can do this with a couple of simple experiments.

Using a Trichlor tablet, hold it on the stain for about 10 minutes. Use a stick or a pool pole, not your finger.

If the stain lightens up it's organic.

You can also use about 1/2 lb. of calcium hypochlorite (granular chlorine) in an old sock to put on a spot. If the stain doesn't lighten up, gets darker or the color changes to black, it's probably a metal stain.

To confirm it's a metal stain, get a Vitamin C tablet (crushed up ascorbic acid), put that in a sock, and place it on the stain. If the stain is removed, you can treat the pool with ascorbic acid.
