So I understand generally about doing a SLAM to eradicate algae. Curious whether algae can proliferate at all in a well balanced pool and whether if there is a very small amount present whether keeping FC in 7-9 range will eventually eradicate any present slowly over time. I'm debating doing a...

thanks, forget abut doing that in poolmath. Looks like 35 oz CYA decreases pH roughly 0.2. That doesn't account for pH falling about .5 or so, but maybe rain was acidic. I did check my lights and crevice where the fiberglass meets in the corners, and I think there is a tiny amount of green algae...

FC 9.5 CC 0 pH 7.2 TA 100 CH 300-325 CYA 60ish I've had cloudy water a couple times last 3 weeks. The first time solar cover had been on for over a week and plenty of small debris had gotten in pool, but this was before it was warm enough to swim and FC was 3 the day I uncovered and water was...

If I need to add 25-30 pounds CaCl2 to get my CH back to 350 or so after winter partial drain and rain and snow refill, will that affect the salt level I measure with strip test for salt or for Taylor salt drop test. Obviously I am not adding sodium but is all the extra chloride contribute to...

Great, thanks for quick answer.

I ordered kit, first time ever for new pool, last spring and used until fall. Is it all good for this year? There is probably enough FAS DPD for this year for me, but the powder has turned from off white new to charcoal. Always stored inside around 70 degrees out of light. I was going to grind...

Warm winter in Ohio, scheduled to open pool end of March by PB, but plan to do myself. I've read the pool opening sticky, but it didn't answer all I needed. I reached under my cover and grabbed a water sample to test, but only reached the top of water, which has risen since end of November from...

I told him to brush once a week anyway since he doesn't have a robot for the floor. Wouldn't vacuuming after letting settle get a lot at once, then brush to circulate more?

First, my pool is sparkling clear thanks to this site. My neighbor had his pool drained, cleaned and refilled 15 months ago after it was covered for 3 seasons by old owner. He has 30k IG with SWG sand filter and uses a Polaris with booster pump to clean. Runs single speed pump 24/7, a waste but...

So, it's finally warming up in Ohio. Heat pump doing ok, got pool up to 75 today and hopefully up closer to 80 tomorrow. Main question is whether it is better to take off solar cover during sunny warmer portion of day while heating or leave on until we swim mid to late day? Either way heat pump...

New pool, need to get CH from125 to 350+ so need a lot of calcium chloride, looking to get a couple 40 lb bags or 25/50 pound bags. I'm in Ohio but missed the winter supply of cheap de-icer options it seems. I can order online from pool supply store but didn't want to spend $150. Has anyone used...

Ok, I have been confused it seems. So the muriatic acid addition actually brings down TA, and the aeration increases pH to normal? For some reason I assumed the aeration decreased the TA and increased pH both. Please confirm. Is there an easy explanation for the acid decreasing TA itself?

I've used the pH test in my TF100 and the kit PB gave me. Been testing every couple days. pH in7.8 range before I added acid a week ago to 7.6, although FC 12-13 then , going down now with CYA going in and FC going down, makes it hard to keep straight. Why wouln't aerating bring down TA, do I...

Tested today at pH 7.3, FC is 10. I had added some muriatic acid to get pH to 7.5, but being a little ignorant maybe, I added 5 pounds CYA 2 days ago as well since I'm trying to get CYA up to 70 from 40. Is CYA a weak acid? No one will use pool until weekend at least because too cold still...

My FC was 12-13 even with SWG on 20% and running pump on 1000rpm. I've left SWG off for 2 days and FC is 10 today. I added 80 oz CYA to shoot for around 60 ppm before going up to 70-80 because I got 30-40 ppm testing and don't want to overshoot. 2/3 of CYA has dissolved in skimmer. I haven't...

First, is there an expiration for CYA? I got a 25 pound pale and will use around 7 pounds this year. I put 5 pounds in a muslin bag I bought to brew beer and threw it in skimmer. Bag is more porous than a tube sock, but there isn't a tube sock to be had in our house or 6. A little bit of the...

Thanks, I only see return gas bubbles when SWG on. Is air relief valve on the filter pressure gauge at the top somewhere? Didn't know there was a relief valve TBH. Haven't figured a lot out yet.

Just learning the ins and outs of my VS pump. On higher speeds there is no air in pump basket. On extended low speed 1000-1750 rpm there are big bubbles in top of basket. My PB said it s because of the lower speeds I have the pump on. I don't understand the principal. Is that a reasonable...

I bought a 25 lb container of CYA online because it was cheaper than local. I need to raise my level from 40-70. I'm going to add to get to 60 using pool math as described. How do most measure the amount? I don't have a kitchen scale, so is there a good way to measure 6 lbs? I could guess at 1/4...

How did you wire a separate clock? Or is it an automated system so you can control different parts of system?

Any good place to get calcium chloride other than a pool store this time of year? i was hoping to run the pump all the time very low except when heating in May and September. There doesn't seem any way to get FC down now without using less pump time or turning off SWG intermittently, which...

Like a little kid with a first chemistry set! Got TF 100 in mail today and tried it all out. Pool filled about 3 weeks ago from hose, we swam twice but bad weather in Ohio mostly pool sitting unused, solar cover on 95% of time. SWG has been on lowest setting since last Sunday, 20% setting after...

Sump pump sounds good, I'm sure it will get some use one way or another. Thanks.

I don't have and overflow and see no way to pump to waste from equipment pad. Guess I could get a small pump like a cover pump although I have a web safety cover. There's a few inches above skimmer to coping so it's not going to spill over coping if that's what you meant. What is main problem if...

First week of filled new pool here in SW Ohio. I can start doing my own chemistry next week, but builder has checked and adjusted to what they say is good. I am using SWG and plan to use TFP methods otherwise. First maybe dumb question. We filled 2/3 up skimmer level, maybe 3/4, and now it's...

I have twins that are almost 10. Others are 14,20, and 24. so 4 still at home at least when college out. All good swimmers with 2 years each of swim team experience, not that means much if they sneak in I guess. Pool access from back door of house with fenced in yard but no fence only for pool...

Have a 12mil cover in the mail from Amazon. That seemed easiest to order from rather than pool installer store. I would use it all the time when no one plans to swim, but wife refuses to look at a reel, so I'll probably cut long ways for 38x18 pool so she can take off before kids and her swim...

Exactly the tidbits I was looking for. Who is this Dave who sells reagents? I'll go for the borates once I get a handle on the rest for a month or so.

Thanks lefty51. What time of day do you run your pump 6 hours? Our pool gets direct sun from maybe 11am to 6pm, so I assume I should include those hours in my run time based on what pool school suggested for using SWG. Then I can check chemistry around 8pm each night once I get a TF-100 kit. Do...

Thanks Pat. I did read those links you posted. I understand the generalities more than the fine tuning I guess. Here in Ohio I will be heating a lot starting in about 10 days with Pentair heat pump. I don't know yet if that means I will be running the heater and pump round the clock or daytime...
