Hi! I am using a drain king to try to unclog my skimmer line. The reason I think it's clogged is because the pump won't prime. (It wasn't working right, and we realized the basket at the pump was full of debris. Thinking some of the debris also got into the ine.). Tried the drain king from...

So we have a plaster pool. I recently brought up the calcium level to 280, but when I did, it threw off the csi result so that it now says “potential for scaling”. I brought the PH down to 7.8, and that made the csi fine. However, within a couple of days, PH was back up to 8.2. My pool tends to...

Hi! I just noticed small white circles floating on the top of my pool. You can see them in the picture to the right of the shadow. At first they almost looked like oil splatters on water because they are perfectly round. We did have pollen floating on the pool, but it wasn’t round and the...

Hi, everyone! I like adding a bottle of chlorine at a time, so I usually do that every other day. This means that I am usually going above the maximum recommended FC level for my Cya. I just came across something that says you can go too high for your cya too protect the chlorine. If the...

Our skimmer didn't seem to have good suction, and so I tried to clear the line using a bladder in case there was a clog. I inserted the bladder in the line from the pump end to shoot water back down the line towards the pool. Nothing came into the skimmer, but now the pump won't prime. It...

I have pollen floating all over the top of my pool. Have never seen it like this before. I am reading on here to use a skimmer sock, but skeptical that that will work because the pollen seems to just be sitting and not going into the filter. We just cleaned the cartridges, and it seems to be...

Ya'll, I am about to cry. I had an algae flare-up, which I haven't had in over two years thanks to you guys. I think it's the dreaded mustard algae. I finally finished shocking (passed OCLT) and raised the FC to mustard algae shock level yesterday. We got 3.5 inches of rain yesterday. When I...

Treating the pool for possible mustard algae. I'm in the SLAM process now. My first question, I read different things about whether mustard algae is slimy. This was definitely slimy. Was planning to raise to mustard shock level for 24 hours, but maybe don't need to if it's not mustard algae...

My pool has been doing great for a couple of years with no algae outbreaks thanks to you guys. However, today, when I was about to jump in, I noticed several yellowish brown patches. ( see pics). They are a little slimy and rub away with my finger Is there anything other than algae this could...

I was just at Wal Mart heaving six bottle of chlorine into my cart when I noticed these Blue Sparkle Skimmer Tabs. The package says “does not contain CYA. Does not contribute to the buildup of stabilizer that makes chlorine less effective.” Has anyone tried these? Can I use these instead of...

Hi, guys. My pool has been using so much chlorine lately. I am putting in a full bottle of 10% bleach every day, which is costing us $80 a month. It has been super hot ( upper 90’s) and we’ve had daily swimming in the pool, but still. My CYA is 50. Should I raise it? Would this help? My...

Hi! So we used to have a vinyl pool and we moved to a house with a plaster pool. I didn't ever worry about calcium levels on the other pool because of the vinyl, so I wasn't in the habit of testing those. The calcium in our new pool was super high when we first moved here. I haven't checked...

I have some staining in my pool that I have determined is iron by using a vitamin C tablet. I read online that this comes from well water. We don't have well water. It can also come from rust of pipes due to low ph. I was having some problems with the ph and didn't do a great job keeping up...

We are getting a light yellowish stain or fading (not sure which) around the edges of our liner on the floor of the pool. Anyone know what this is?

We started having trouble with our pool and called a repair person. She said the pump wasn't priming at all and we needed to replace it. After she replaced it, she discovered that the skimmmer line was also clogged. She tried to unclog it (I think with a hose) and couldn't get it. She didn't...

My husband and I went away for ten days and had my brother add chlorine to the pool while we were gone. I forgot to tell him to also backwash, so by the time we returned, the water wasn't circulating. The pool was still clear, but there was brownish algae creeping across the floor. I...

I accidentally drained most of my pool and have refilled it. I am rebalancing the chemicals. The pool contractor I spoke with (who is going to help me with my liner issues in the spring--as draining the pool caused wrinkles and pulling away of the vinyl liner) said to be sure I get the TA back...

I accidentally drained my pool last night. I was letting out water because of excessive rain, and when I put the pump back on, I turned it to backwash instead of filter. Almost all the water drained. The liner is coming loose (puffy) in several places. Do we just fill it back up, or do we...

When my hubby was taking care of the pool using the pool store, I would notice it would turn greenish after the kids had been in it. Once I found Pool School, I shocked it, and it began looking a good bit better. Not crystal clear, but very clear in the shallow end and just slightly cloudy in...

Our CYA is 80, and I'd like to do a partial drain to bring it down. The pool calculator tells me I'll need to drain half of it to get it to 40. Can anyone tell me the steps I should follow to do this partial drain? I've tried to research it and am getting very confused by all the different...

We are new pool owners and I think we've goofed. I just returned from the pool store, and here are our numbers: FC 1.1, Total Cl 1.6, CC .5, pH 7.8, Alkalinity 92, CYA 95. Reading on here, I'm learning that our CYA is way too high and we must drain 60% of our pool. Yet the pool store said...
