Not using a cover and have never used anything with sulfamic acid. I replastered the pool late last year, so water is new. I'll keep it at SLAM level for a few more days then. It does cost me though, since the pump is running 24/7 and I'm using about a gallon of chlorine / day. :) Thanks everyone.

Started SLAM'ing 3 nights ago. I'm on my 3rd morning, so I've performed 3 overnight FC loss tests. Water was completely transparent and blue to begin with - no Algae whatsoever - but I had 0 chlorine. I also had 0 CYA, so I brought it up to 30-40ppm. I brought pH down to 7.3 and TA ended up...

Information about the algaecide I added: https://cdn.lesliespool.com/wpdf/Leslie's Black Algae Killer Label.pdf. However, the problem started happening before I added the algaecide.

New thread for the chlorine problem, containing the reads from this morning: No longer exists. Merged with this thread.

The chlorine problem happened before I added the algaecide and after though.

Thanks for the support Chris. Here's the label of the product I added: https://cdn.lesliespool.com/wpdf/Leslie's%20Black%20Algae%20Killer%20Label.pdf.

Hi there. Taking care of this pool for the past 3 years and recently (this past weekend) fought what appears to be a black algae problem successfully. Now I have a mystery that I don't even know where to start! Here's my TF-100 results: FC: 0.5 CC: 0.5 Phosphates: ~150 (added Phos Free around...

Thanks everyone for your insights. The first thing I tried here was the SLAM method. I set the pH to 7.2 and dumped 5 gallons of Chlorine in the pool. Next morning, I had an FC of 0.5 and CC of 0.5. I couldn't believe it! I also tried the cheaper testing method for Chlorine that comes with the...

TF-100

Hey! I have some Brown Algae in my pool that doesn’t brush off easily with a nylon brush. It has a slimy consistency and proliferates upon low chlorine and reduces when I shock the pool. The guys at two different stores said they’d never seen something like it. They recommended treating like...

Thanks Jim! That's a very interesting point of view. The reason why I mentioned the circulation problems is the main drain is on one side of the pool, the skimmer is on the opposite side, and the two jets dispense water back into the pool are basically in the middle of the drain and the...

Moved to this house 1.5 years ago and have been maintaining this 30+ y.o. pool ever since. My main drain doesn't have any suction and that sucks (no pun intended). All the suction is being done by the skimmer and that leads to really bad circulation. The pool wasn't designed to have this...
