    Preparing to SLAM

    Moved from here. I'd like to piggyback here, as I'm about to start a SLAM myself. I'm trying to get rid of 2 tiny spots of black algae (both less than dime size), one small spot of green algae (less than a quarter), and the remnants of mustard algae (this was kind of bad, and I shocked it...

    SO. MANY. PROBLEMS.

    I’m a fairly new pool owner.. bought this house with a pool about 2 years ago and have had nothing but problems with keeping it up. I even had to drain it completely last year and refill. I think one of the main problems is just age.. the house is about 20 years old and I’m thinking the pool...

    The undead Algae

    Hi, I am new to the thread and still reading a few things. I have been a pool owner for 7 years and I am at my wits end with this pool. This algae won't die and the running joke is that it is the undead Algae. I have been told this is algae - it is spotty and seems to be in the crevasses of...

    Skimmer switched drain holes

    Hi TFP members, I’ve had this pool for 5 years now, it is much older than that, but every year seems there seems to be a new challenge to get the water clear. I switched 2yrs ago to liquid chlorine that I add daily with a couple of chlorinated pucks thrown in to keep the cya up. Last year was...

    Mystery stains on liner

    Hi all, I'm stumped on this one. So this little patch of yellow/brown stain appeared towards the end of last season. Can't brush it off, looks like a stain but thought it might be organic so I SLAMmed. I worked hard to keep FC greater than 30 ppm for a few weeks but the stain remained, and it...

    Don’t Judge! Tons of algae

    FC 0 pH 8 CYA <30 TA 80 Mucho algae (floating & at the bottom)- doing mustard shock levels after initial SLAM just to be sure! Just used my test kit for the 1st time. I’ve read & made notes on Pool School articles, but want to make sure I’ve got my order correct before dumping chemicals: 1.)...

    Post Floc, Still Cloudy-HELP!

    Hello guys. First post here. This is the second summer that I have had my pool. This summer has been a night mare trying to get the chemicals right. We’ve only swimmed in in once and I’ve had it opened for about 6 weeks. The chlorine will not keep. It hasnt gotten above 1 ppm if that. Most of...

    Calcium Spots or Black Alage

    I have been dealing with these hard white/grayish spots on the bottom and walls of my concrete pool. I am in the middle of a SLAM/MUSTARD algae shock as we speak. The reason for this is that I did also have some issues with algae. I recently connected new Intellichlor salt water system and...

    Pressure Rising very fast

    My 72 year old (female) Friend had an algae problem caused by a broken pump motor and a lot of leaves. I replaced to broken motor, cleaned to DE Filter, got as many of the leaves out as possible without being able to see the bottom of the pool. I Shocked the pool and ran the pump until my...
