    Trouble with Stains

    The problem with winter treatment (or even early fall around here) is the Jack's #2 treatment instructions say 65F minimum water temperature!

    Spa Borate "Aeromatherepy" Stings Eyes?

    Sorry to throw you off, JamesW. I was just joking about "aromatherapy." Years ago, spas were sold with extra features to put aromas into the jet airflow. I don't even know if they are available anymore. What I'm experiencing is definitely not positive therapy and I"m trying to get to the bottom...

    Spa Borate "Aeromatherepy" Stings Eyes?

    I'll try that, JoyfulNoise. Maybe the FC is bothering me in my old age. The last time I had a spa I was in my late 20s and I don't recall this problem.

    Spa Borate "Aeromatherepy" Stings Eyes?

    My spa tests 30 ppm for borate and my pool tests 50 ppm. Both pool and spa run around pH= 7.3, CYA=30, FC=3-5, and CC always under 0.5 ppm. I run my CA and TA lower in the spa than my Gunite IG pool too--at CA=150 and TA=50. Years ago I owned and maintained a spa and never used Borax. With this...

    Best Places to Buy Liquid Chlorine

    I'm not finding such great end of season LC sales this year, but at the end of last season I bough a bunch of fresh 10% LC at half price or less (mostly at our nearest KMart, which doesn't even have LC this year). Motivated by an LC concentration vs. temperature half-life graph that I found in...

    Epoxy Putty Fail (Suggestions and Advice Much Appreciated)

    I found something that Leakmaster Pool Putter prefers to stick to less than pool plaster. Forget about using the polyethylene wrapper or an applicator cut from an HDPE milk jug. Just like skin or nitrile gloves, the putty prefers to stick to them over plaster. The solution was wax paper! My...

    Epoxy Putty Fail (Suggestions and Advice Much Appreciated)

    It would be nice if I could push out a re-plaster job with some kind of compound or temporary fix. The rest of the plaster is holding up for now. I need to learn what other items should be overhauled at the same time as a re-plaster job. I'd like to have a new concrete deck poured and an...

    Epoxy Putty Fail (Suggestions and Advice Much Appreciated)

    Thanks for your help, ajw22! A bucket test reveals that the pool is not leaking. (I recently fixed a 165 gal. / day underground leak by disconnecting some old defective solar panel pipes but that leak is unrelated to this effort.) The plaster around the perimeter of the two PVC returns in the...

    Epoxy Putty Fail (Suggestions and Advice Much Appreciated)

    My old Gunite pool has some chipping in the plaster around the returns so I decided to try to patch it with Leakmaster Pool Repair Putty. The problem is the putty sticks to everything better than the plaster! The instructions suggest not overworking it and just pressing it onto the damaged...

    Need help with SWG cost analysis (specifically, salt consumption estimate).

    Thanks so much, everyone! I think there's an SWG in my future. I recently bypassed a nasty underground plumbing leak (~165 gal. / day) to some old leaking and worthless solar panels by replumbing and bypassing the leaking pipes. I left a nice spot on the equipment pad in the pump shed for...

    Need help with SWG cost analysis (specifically, salt consumption estimate).

    With the increase in LC prices this year, I decided to try to pencil out the costs of running a Jandy Truclear SWG. I lose about 2 ppm FC from my pool per day during the hot summer months. At current Walmart bleach prices (best non-sale LC price locally), that's about $1.50 per day! Last year I...

    Copper BB stain

    While I agree that the red hue does not typically indicate copper, copper plated BBs are quite common: Search Results I think I've even seen those Crosman Copperhead BBs in local stores like Walmart. After removing dark gray stains from my pool with Metal Magic and then testing the remaining...

    Pool size reverse calculation

    Yes. If you're willing to measure reagents in some manner that improves upon drop resolution and accuracy (how big is a drop from any given nozzle?), then many tests can be better used to estimate pool volume.

    Pool size reverse calculation

    Also, if you do a formal error analysis of the method (which I've not taken the time to do either), you'll find that a dichlor / calhypo FC based method can provide superior error levels by conducting the test multiple times. You have to add chlorine to your pool anyway and the addition of CYA...

    Pool size reverse calculation

    It's tough to know the strength of liquid chlorine, because it degrades with sunlight, time, and temperature, but what do you think about weighing out some quick dissolving dichlor or calcium hypochlorite for a test? I bet factory packaging that provides a percentage of chlorine /usable chlorine...

    Stain Wars--Planning the Next Assault!

    The color is allegedly an indication of the type of metal ions. I had the Culator in my pool for two months before I did the MM treatment and the Culator did not change in appearance during the entire two months. Within a couple of weeks of the MM treatment, which dissolved essentially all my...

    Stain Wars--Planning the Next Assault!

    I did a Metal Magic sponge test late last season and it indicated that I treat my stains with the maximum dose of MM. (Here are the highlights of that battle: Sequestrant vs. CYA Bound Chlorine ). The MM lifted nearly all my dark gray stains and I continued to treat with a maintenance dose of...

    Unusual stains: Fiberglass pool

    Thanks for your reply, danobrien. The multiple packet Jack's test didn't improve on the result of the singular application of Copper and Scale Stuff. The Copper and Scale Stuff was better than anything else I've tried on these tan stains, but my guess is it will take a long time to fully lift...

    Unusual stains: Fiberglass pool

    Thanks for the information! I'm contemplating the Jack's Copper and Scale Stuff treatment myself. I'm glad it worked for you and it worked quickly. I removed what were surely iron stains in our pool (from spring water fills) late last season using the maximum dose of Metal Magic but it didn't...

    How long does it take your water to heat up?

    It turns out that even the heat from my recirc pump 1/15 HP can keep the water from dropping lower than 99F when the night air isn't too cold (near 70) so that's how I "beat" the physics of the heater only output! My spa is well insulated, but most of insulation is in the walls and floor of the...

    Unusual stains: Fiberglass pool

    Though it's not covered in the Jack's Magic Stain Identification Kit or The Copper and Scale Stuff instructions, Jack recommends using The Purple Stuff instead of The Blue Stuff for high TDS (or salt pool) stain removal. Scroll down to the flow chart here: Our Program | Jacks Magic The...

    This is weird. I took the cover off the pool. it didn't look too bad. Bought nine bottles of bleach.

    I'm in N. Central Idaho so similar to your winters in Maine. I've lived here for a couple of years and have twice opened my pool to zero CYA. Fortunately, my pool responded to chlorine additions as expected and held FC from day one this year.

    In The Dark About CC Removal!

    I just got it up and running so I haven't changed it at all yet. I've only used it once so far and afterwards I found the last leak and drained it to do the repair. I've not used it since refilling it. That Ahh-Some stuff looks good, but I've had several hoses off the spa and they all look...

    In The Dark About CC Removal!

    Or rather my spa is in the dark (full shade gazebo-covered). Given the near absence of UV light, I've searched these forums and found a few claims that aeration removes CC, but I'd like to hear what the chem experts have to say about it. Once the FC reacts with organics and makes the stinky and...

    How long does it take your water to heat up?

    Just skip to "The Bottom Line", below, if you're only interested in making warm-up time estimates (the topic at hand of this thread). I just made several repairs on an old outdoor (gazebo covered) spa that came with the house we bought 1-1/2 years ago. I powered it up yesterday. After...

    Start SLAMing without Chlorine FAS/DPD test (my experiences--YMMV)!

    Agreed. I used more bleach than necessary too but it was still within the realm of mustard algae treatment dosage (which wasn't my problem) and it did the trick for me. SLAM treatments are not a one size fits all maladies prescription and I think it's possible to sometimes err on the aggressive...

    Sequestrant vs. CYA Bound Chlorine

    After nearly 3 weeks of cloudy water, I'm pleased to report that the "care package" I received from Pro Team cleared the pool literally overnight! After deep cleaning my sand filter (as described in the previous post), I received the package from Pro Team the very next day and followed the...

    Sequestrant vs. CYA Bound Chlorine

    I removed my Sandpiper lid and deep cleaned the sand. The lid wouldn't budge by hand and the seal is right there in the gap between the tank and lid, offering no way to pry without contacting the seal. Rather than prying, I gently tapped one of these narrow wedge shaped nylon pry bar tips...
