    Remove old plaster or sand blast?

    I think I do an excellent job of testing, and recording, on a daily basis during run-up early season, then backing off when weather, sun exposure stabilize. I have Excel data going back to 2012. Until I finally realized that the stains on the side of my pool were yellow algae, I had to up the...

    Remove old plaster or sand blast?

    Sorry, I already posted a new thread about leak detection/management. (Merged threads - TFP Mod) Next question has to do with the new material. I've had plain, basic white plaster. Now I'm thinking about color and texture, which my neighbors have. The first pool contractor mentions three...

    Remove old plaster or sand blast?

    Thanks. That's what the last two "leak detectors" were doing when they trashed the manifold. They disconnected pipes, attached heavy fittings to the end of the unsupprted pipes to pressurize them, and bang! Everything on the ground. I think a potential problem is with the suction lines. One...

    Remove old plaster or sand blast?

    Our pool was built in 1978. Toward end of August I noticed I was adding more water than usual. By mid-September I was pretty sure, and started bucket test. No wet spots along any visible surface above the pipes. With normal pump run of around 8 hrs, including booster pump for pool sweep...

    Remove old plaster or sand blast?

    Thanks for the replies. The "boss" has not been out yet. The young man who did the measurements mentioned sand blasting, which I had never heard of, and certainly not on the prior re-plastering. Except for the straky stains on one of the sidewalls, and the hairline crack, there are no other...

    Remove old plaster or sand blast?

    We're getting bids now to do some renovation on our pool, built in 1978. Original deck is exposed aggregate, the stones are falling out, and the deck has many cracks. Fairly straightforward, going with a smooth finish. We've had it replastered twice, last time in 2007. The plaster has one...

    Yellow/mustard algae, forever?

    Red Beard, thanks. Evening FC around 6, AM around 8. Loss of 2ppm, or 25%, pretty consistent with CYA at somewhere between 35-40. I think I'll leave it as is, since I'm in a regular routine, adding 2ppm worth of bleach every evening. Once the season advances, and there is less sun exposure...

    Yellow/mustard algae, forever?

    Thanks to all for the info, advice. Because I have some difficulty carrying jugs of bleach out to the pool, I was hoping to be able to reduce the volume needed every evening, not necessarily to save a few dollars, but to save my back, hip, etc. So, for me, it is not much different needing to...

    Yellow/mustard algae, forever?

    Thanks to all. We are in central California. Near 100 F, full sun around 9AM-4PM. I've thought about raising the CYA, but that would mean higher FC to kill algae, and probably more $. I misstated prior FC levels. Used to keep it between 5/3, adding around 42 oz of 10% bleach each evening...

    Yellow/mustard algae, forever?

    I've had intermittent yellow streaks/smudges along the North facing wall of our pool for years. I tried to convince myself that it was discoloration of the plaster, and would scrub with brushes, stainless steel brushes and a pumice stone. I would keep the FC around 4 minimum, 6 after adding...

    Falling CYA level

    Thanks for the reference on CYA. We are in Stockton, CA, and have had several 100+ days, but the pool is usually 82-85. I swim laps, but our 5 y/o grandson is in on weekends, so there is little splash loss. No leaks as far as I know. I never let the FC get below 4; I kept the FC level 2-4...

    Falling CYA level

    I've been adding gallons of 10% bleach this summer, per PoolMath calculator, to prevent a recurrence of yellow/mustard algae this spring. I finally decided to test the CYA (using all fresh TFT reagents). I was shocked to find it somewhere between 1-15, confirmed by multiple water samples, and...

    Using a floating chlorine dispenser while away? Suggestions appreciated

    You don't indicate how long you will be away. I think you ought to invest in a new chlorinator. If I remember right, the ones that are available everywhere hold around 6 large tabs, which would be good for probably a week, or longer. Is there someone who could 1) test, 2) replenish the tabs...

    Dirt or algae?

    Hi fellow pool sufferers, I mean lovers. I took the cover off my filter. The elements, installed new on 4/10/17, show a little dirt, but nowhere what should be accumulated after nearly 2 months. Next, I closed the baffles on the skimmer inlets, so all suction goes through the bottom drain...

    Dirt or algae?

    Thanks to all for replies. OCLT: PM: 4.5; AM 4.0, CC: 0.0 No apparent excess chlorine consumption, or binding to bad stuff. The stains on the sides are streaky, and appear greenish, so probably algae. But, I tend to pour the bleach in that area, so maybe stains. They do not brush off very...
