    High CC but clear water

    Yesterday, I added several pounds of dichlor shock to get FC up to shock level, in preparation for closing on Monday. A lot of leaves blew into the pool overnight which apparently caused havoc with my water chemistry because it is showing a CC level of 1.5 now. It also showed that I lost at...

    Ideal CYA, PH and TA when closing a mesh-covered pool

    What is the ideal CYA, PH and TA level when closing a pool with a mesh cover that typically has to be drained 4-5 times over the winter to keep water level below the tiles all winter? Last year I opened up to a swamp with 0 CYA, low TA and high PH that took a long time to clear up so I need to...

    Fiberglass pool settlement problems

    The concrete cantilever coping above the tile line in my fiberglass pool is cracking significantly in all 4 corners and small chunks of concrete have been chipping off for several years now. A fiberglass pool company tells me that the problem is caused by settlement and a dewatering system...

    Sand filter making crackling sound and water found near sand filter & pump

    This morning, when I went to turn the pump on for the day, I noticed that the ground around the pump and sand filter was wet. I turned the pump on, and the sand filter was making a strange crackling noise. I didn't see any water leaking from the pump or sand filter when the pump was running...

    Vacation advice needed

    I’m thinking about putting our mesh safety cover on our pool before we go on vacation in a few weeks so I don’t have to ask anyone to come over twice a day to dump out the skimmer baskets. Our pool is surrounded by trees so I’m hoping that covering the pool will decrease our chances of coming...

    Questions before a SLAM

    I just opened up our pool. The water is greener than usual because I opened the pool so late. Pool is surrounded by trees so I blindly tried to get the leaves out of the pool that blew under the cover, but I may have missed some since I can't see the bottom. Here are our test results...

    Questions before opening pool ourselves for the first time

    We are going to open up the pool ourselves this weekend for the first time instead of paying a local pool company $250 to do it. I have watched several Youtube videos and read the information on this forum and it looks fairly simple to me. Before we start opening it, I have a few questions...

    Polyquat goof before closing

    When I added the polyquat to my pool this morning, it came out of the bottle much faster than I expected and I ended up dumping the majority of the 32-ounce bottle into one small area in the deep end. I only got about 3-4 ounces of the bottle into the shallow end. I ended up adding 10 more...

    Using cal-hypo temporarily for daily chlorination

    I can’t find any liquid chlorine in my local stores so I was thinking about using cal-hypo for daily chlorination until our pool service comes to close our pool on Friday. We plan on closing at half shock level since we are using polyquat at closing so I will just be using the cal-hypo to keep...

    Closing with mesh cover before water temperature is below 60 degrees

    Our pool closing is scheduled for next Friday. Water temperature is 68 degrees now so I doubt that It will be below 60 in 7 days when we close. Our pool is surrounded by trees that are dropping leaves into the pool constantly right now, so I really don’t want to postpone the closing because of...

    Difficulty finding pool safe bleach and liquid chlorine

    I went to every hardware store, superstore and farm store in my town that sells liquid chlorine and everyone is out of it. In previous years, all of the local stores stopped stocking it in September so I doubt that any of our local stores will get more in. Unfortunately, only one local pool...

    Advice needed regarding pool leak detection

    I need some advice from one of the knowledgeable pool professionals on here about the leak we are experiencing in our pool. We are losing approximately 1/2 inch of water each night with the pump off and about 1/4 inch of water during the day with the pump running. When this leak started, we...

    Pool is leaking 1/2 inch a day

    I posted a few days ago about a steady drip that was coming out of our pool heater that was causing us to lose 1/2 inch of water a day. A pool pro came over yesterday and replaced some switch that caused the drip to stop. This morning, I went out to turn on the pump and check the pool and we had...

    Pool losing 1/4-1/2 inch of water a day and there is a lot of water around the gas heater

    My pool is losing approximately 1/4-1/2 inch of water a day. When this leak was first discovered, I noticed that there was a lot of water around my gas pool heater and saltwater generator cell that is on the ground next to the heater. The heaviest amount of water is around the heater so I...

    Adding CYA to pool

    I need to add 4 pounds of CYA to our pool so we can start using the salt water generator. I’m running out of liquid chlorine and can’t find any more in my local stores so I need to get it into the water as quickly as possible. If I put it into several pairs of knee-high pantyhose instead of...

    Cantilever coping cracks

    Our older fiberglass pool appears to be settling. The cantilever coping inside our pool has been cracking at the corners for several years now. Chunks of concrete have come off in several places, exposing the white fiberglass underneath. It looks unslighly, and I'm afraid tiles are going to...

    low PH, TA and CYA

    I need some advice on what chemicals to add before a slam. At opening, PH was extremely high at 8.0 or probably higher. TA was 60, calcium was 120, CC was .5 and CYA appeared to be 0 or possibly 20. I immediately added some muriatic acid to lower the PH and it looks like I didn’t eyeball it...

    Question regarding using HTH stabilizer pods during a SLAM

    I'm starting a slam today since my pool is full of algae at opening. CYA is 0 so I have to increase it during the slam. The only CYA they had in my local store were these HTH stabilizer pods. Reviews online say they dissolve quickly. Since I'm going to have to backwash often during the slam...

    lowering PH after adding chlorine

    I started a SLAM this morning and forgot to lower the PH before I added some chlorine. PH was 8.0 at opening. I only added 2 jugs of chlorine before I remembered that I needed to lower the PH first. Should I go ahead and add some muriatic acid now? If so, how long should I wait after adding...

    Extremely high PH and high CC after adding polyquat

    Last night, I added 30 Oz of Super Algeabomb 60 to my pool, which is a polyquat product. My FC was slightly above half shock level (14) so one of the moderators on here told me to add it at the maximum dosage allowed on the label. This morning, I tested my pool and FC dropped from 14 to 10, CC...

    Can I close tomorrow with polyquat if FC is 14?

    My pool closing is tomorrow and FC has only gone down to 14, which is 4 ppms above 1/2 shock with a CYA of 50. Water temperature isn’t below 60 yet and I have a mesh cover so I really wanted to use it. I was planning on adding it tonight. Will it still be effective if I add it or would I be...
