    Going nuclear on algae. What to use?

    I'm curious, why should the floc not get in the filter?

    Going nuclear on algae. What to use?

    I’m having my liner replaced but the installer can’t measure for the new liner until the water is clear. Pool was BLACK 10 days ago. I SLAMMED everyday for a week and got it to neon green but still opaque. Then Hurricane Ian came through and we lost power for 2 days and now its heading back to...

    Stiff nylon brush for black algae in vinyl pool

    I was going to replace the liner last fall but when my pool guy looked at it he said "no way". He said that even though it was faded and a had a few wrinkles, it was holding water just fine. He also said that "these older liners are a lot more durable than the newer ones because they have more...

    Stiff nylon brush for black algae in vinyl pool

    I have black algae in my vinyl pool. Yes, I know it's not supposed to get in vinyl pools because of the slick vinyl surface, but my liner is old and porous. The black dots of algae smear green and can be scrubbed off but not with my regular nylon pool brush. I've gotten the spots off of the...

    Is this dead algae? Not filtering out. What 2 do? PICS

    It's pretty hard to tell but it looks like they are coming in from the pipe. I ran the hose over all of the suction side fittings while the pump was running. When the fitting just before the pump basket was covered with water the bubbles were substantially reduced. So I'm guessing that's...

    Is this dead algae? Not filtering out. What 2 do? PICS

    I have not, but am very suspicious of that too. I was all ready to take it apart this past weekend when I discovered the darned thing is not plumbed with unions and I would have to saw the pipes apart. I'm pretty handy, but not that handy. Maybe it's time to call a pool company. I've got a...

    Is this dead algae? Not filtering out. What 2 do? PICS

    After shocking the swamp for 2 weeks at FC=34, I'm quite sure the algae is dead. Had to floc to get everything to fall and then I vacuumed to waste. Trouble is, I still have junk falling and collecting but no longer enough water to vacuum to waste again. When I tried vacuuming through filter...

    Iron precipitating out?!? What just happened?

    Here are my numbers: FC= 7 CC= .5 TA= 110 CH=40 CYA=50 (was at 60 before all the rain and added h20) PH=7.4 And here's a pic of the precipitate: [attachment=0:czyqpwue]iron in skimmer.JPG[/attachment:czyqpwue] I've only seen this precipitate in the skimmer and have no rust stains anywhere...

    Iron precipitating out?!? What just happened?

    Bought a house with a swamp and have been doing the shock process for two weeks. Keeping FC at 34 the whole time. Began to wonder if filter wasn't working properly since I was losing no FC overnight but water was still completely cloudy and greenish, so I used a Flocculant. Lo and behold...

    my 1st opening-shocking algae-?s about backwashing,rain, etc

    Re: my 1st opening-shocking algae-?s about backwashing,rain, agggh...that's what I was afraid of. Oh well. I've only lost a day. Will go add the DE back right now. So no worries about straining the pump? It definitely sounded "different" when the jets were slow. And I'm guessing the...

    my 1st opening-shocking algae-?s about backwashing,rain, etc

    Re: my 1st opening-shocking algae-?s about backwashing,rain, I tried a little DE and the water did clear up a teeny tiny bit (about 4"-6" more visibility). I noticed that the pressure coming out of the jets went WAY down though, so after 2 days I backwashed it out. Pressure returned to...

    Re: my 1st opening-shocking algae-?s about backwashing,rain, Thanks for the link about adding DE! I knew I had read that post earlier but couldn't find it again. I'm also thinking about turning off the pump for a couple of hours and letting the junk settle, then vacuuming to waste. We've...

    my 1st opening-shocking algae-?s about backwashing,rain, etc

    Re: my 1st opening-shocking algae-?s about backwashing,rain, I've been shocking for a full week now an seemed to have reached a plateau. Free Chlorine is holding steady overnight, CC is hovering around 1, but water is not clearing at all. When I started visibility was 1" and by day three I...

    Re: my 1st opening-shocking algae-?s about backwashing,rain, hmmm...sand doesn't wear out or need to be changed?....Looks like I really was POOL STORED!! I'm no where near being close to seeing the bottom so I have no idea how much crud is still down there. I did vac once before I started...

    my 1st opening-shocking algae-?s about backwashing,rain, etc

    We just bought a house with a pool that sat uncovered for 2 years. After scooping 3 bags of leaves, 1000+ worms and tadpoles, 20+ frogs, 2 turtles, and 1 "God only knows what", I got the pump running and....ok, don't freak out.....took a sample to the pool store and asked them what to do...
