I am reviving this old thread because I just had my stamped concrete deck sealed again. I had major drips down the top of my fiberglass pool above the water line. I used acetone, (the kind you get at the hardware store, not fingernail polish remover), and it worked great. I used a cottonball...

I live in Michigan and now open the first week of June every year with a mesh cover that makes my water turn green no matter what. A week before opening I put a pump attached to a garden hose in one end of the pool underwater on the stairs(I lift up the mesh cover on two same side corners), and...

I live in Michigan so I am in the same situation. I have a mesh cover. I use to open it in April (it still opened green, and no one swam in it, I was just using a lot of electricity!) but now I wait until the first week of June. About 2 weeks before opening I use a submersible pump with a...

I had the same problem a few years ago, cleaning the chlorine test tube worked. It drove me crazy until I figured that out. Now I just get a new tube every year.

Wow, this is what 50 looks like? I have been reading my tests wrong for 8 years now because I consider this photo as "still being able to see the dot". I would have added more to make "my" reading lower than what it actually is.

Just wondering. I went from CYA 0 to showing 50 then 40 after adding 2 pounds. Then to 20 then to 40 after adding another pound. My pool is good, but I am wondering if it takes a few weeks after opening to become stable. I'm doing the " look once and look away " method. I need to put my reading...

Re: Has anyone put a "cover mate" under your mesh safety cover at closing? I started this thread last summer asking about the covermate. I never did get the covermate, just closed the pool like usual with just the older mesh cover. I then decided to open the pool on June 4th, 2018...

Thanks pool amateur on the best wishes for my health! Yes I am on a well. I top off with my hose but wouldn't ever fill with this water. I only trucked in water that one time when I bought this house, used only the full mesh cover since then. I'm sure the "partial" mesh cover might work but I...

Thank you for your replies! Hi Swampwoman. Yes I am familiar with the recommendations of closing late and opening early. Ive tried several different variables with timing. I found that unless I open it super early in April, it only takes a few days of hot sunny weather to make the pool...

I'm thinking about buying a "cover mate" cover to put on the water under my mesh safety cover when closing. I'm in Michigan and would like to close my pool earlier this year, probably in September. I have no problem clearing my green pool when I open in May, but due to closing it earlier in...

I have cobalt stains in my fiberglass pool. Not sure if this is what you have or if your pool can get them but they look similar...There was a post in the "Chemistry 201" sub forum with pictures. I dont know how to put the link here but it is titled "Black Mystery Stains" on 06/20/12. Mine...

June 1st with photo For everyone interested in my thread, wanted to do an update with my photo. I have been a member here for 4 years now, I use the TF test kit, I dont take my water to the pool store, I use liquid chlorine only...... Listen to these experts here, you will have your pool...

Re: Need advice. Caulking between fiberglass steps and deck I had the same question and it was answered. I dont know how to forward the link. So if you do a search under my screen name look for the post that says "dirt under cement coping" with photos. Hope this helps.

The picture above is the shallow end, this is the deep end

My trouble free pool. Finally did overnight test and passed..hard to figure out time to do it when I work full time. Put heater on today in this Michigan cold weather. Water is 65 degrees, trying to heat it up so kids can swim tomorrow...This photo is today in the 8 foot deep end. The pollen...

05/17/13 Day 7 Had to raise PH with 2 cups of Borax mixed in water. My PH readings were below 7.2 with high FC. After backwashing twice stabilizer measured down to 20 so am adding more to bring to 40 because I know I am close. I am not going to perform the overnight test yet because the...

Photo of Day 4 after opening. Continuing to shock, vacuum twice, more brushing, backwash once after reading rose 8 points. I can finally see the main drain in deep end today. PH 7.2 FC 16.5 CC 1 CYA 30 Question for the experts. My PH is 7.2 with FC at 16.5 I know the PH reading will be high...

Opened 2 days ago, mesh cover.. It snowed today! Anyways hopefully not much longer to go. My test results before adding anything were: PH 8.2 FC 0 CC CYA About 10 TA 60 CH 270 Added acid, stabilizer to about 30, and liquid 12.5% chlorine only for now. Vacummed once and several brushing...

I have the same black dots with the flare out "tails" that you do. I have several but they are only as big as the smaller one in your bottom picture. Have never figured out what they are. I have tried to find pictures of what cobalt staining looks like but haven't been successful. They are...

Ok. Thanks Dave. Will get the polyurethane caulk and try it.

Yes, the white is the pool wall (bottom). The picture is sideways. The cement is gray on the right, stamped concrete deck, which has about an inch overhang all around the pool. Yes the gap is in center and is like that mainly around the whole pool. When water is splashed up onto the cement a...
