Climate: very moderate, maybe 3-4 mild freeze days, temps in the upper 20's. It's too cold to swim, so what is the most cost effective approach. Changes this year: replaced single speed, 3500 rpm pool motor with variable. During the swimming season can only dial it back to 2500 as we have a...

from pool school Chlorine / CYA Chart Perhaps a cornerstone element of BBB is understanding the relationship between the chlorine in your pool and the stabilizer you put in to protect the chlorine from the sun. Generally, the more stabilizer, the more chlorine you need to maintain its...

Thought I'ld provide a report on my experience with yellow out. I tried it as I thought I had mustard algae and super shock was not removing it. Yellowout was easy to apply and wiped out any visible algae very very quickly. HOWEVER, it has a nasty side effect. FC drops for many many days after...

I've been using the 12% shock, ie double strength bleach from leslies/lowes/home depot. It's a pain to carry the liquids, are there any good powder alternatives? Leslies carries: power powder plus-- 65-70% Calcium Hypochlorite, no disclosure of other chems, no stabilizer ie cya includes...

Opps, treated the pool, again and again, for yellow algae, but just figured out tonight most of the yellow/green stuff on the East side of the pool is not algae, but reflections of the trees and tall bushes making a green wall in back. I was distracted by the falling FC of .5 to 1.0/night and...

Pool school has a FC test of no more than .5 FC change in 24 hours. I've been looking for a normal FC checklist and not finding it. I expect to find something like this Overnight FC change, evaluation, checklist of observations needed 0-.5 excellent, no action need 5+, danger, check...

Pool surface area is 800 SF. Current solar heating panels are 600SF. Climate zone 8/9. rainy winters, hot summers, few clouds What I would like to know: 1- is there a formula given a- pool surface b-solar surface c-outside temp d-water flow rate e-starting water temp f- no pool cover results...

CYA (Stabilizer) Minimum FC Target FC Shock FC 60 5 7 24 I assumed from this chart that if you keep FC between 5 and 7 you won't have algae. However I have found algae can grow well at 7 FC. Yes can treat with shock, again, but would rather...

Darn, darn, darn. After dropping water treatment service and following the advice here the water has stayed clear and swimable for 2 months, and now... -- it's not quite warm enough @ 76, surface area is 800 SF, solar panels are 600SF. Run time has been about 3 hours/day. Increased run time to...

So the other day when I checked water it was FC at 7.0 and PH @ 7.2 and the water literally sparkled. It has stayed clear and algae free on plaster, but seems to have a bit of opacity to it. Are there particular values asssociated with sparkling. Pool store guessed without testing that it was...

Guessing this is still in the getting started forum. Have a single speed pump and want to go to a variable speed for noise and energy relief. What questions do we need to ask? Leslie is recommending Hayward over Pentair and one review of Pentair said there's an issue with electronic parts not...

I know the directions say add one, wait 2 hours and then add the other, but is it really necessary? What's the worst that can happen? Yesterday I was short of time so put both in and it seemed to work ok.

Just fair subject line, but questions about pool plaster and coatings. Inground pool is about 7 years old. Plaster by two "drains" has lifted about 7"x8". It appears like the coating has raised, but not sure. Have not investigated. About a year ago some unknown "repairs" were done, but no idea...

Our pool pump is noise. It's a 1 hp and runs at about 3400 rpm. Questions: 1- there are high effeciency furnances, is there such a thing as a high efficiency pump 2- Looked at the maker's site and they have about 50 different pumps, how do you start narrowing down the selection process? 3- 1...

The directions always say put into a 5 gal bucket and then the pool. Is that just for safety so there's less chance of spilling on yourself, or is there another reason for the directions?

Taylor kit arrived and I ran a few tests, but super super tired, so may need to run more tomorrow. TEST RESULTS cya==70 FC==9 CC==0 PH==8.0 AD==3.5 POOL CONDITIONS some algae growing moderately clear [ very hard to tell as plaster is moddled ocean water color] temp is about 76 highs next 8...

Don't have test kit yet. Chlorine was normal and ph was normal, but I used up chlorine and need to get more. tabs seem less messy, but not sure which is better to use, thinking liquid but wife thinks tabs are better and I don't have a good response as to why liquid is better

I have a manual for servicing the pool filter. I'm afraid I might mess something up because what I see is not what I am expecting. I'm expecting a check/shutoff value to the rooftop solar so I can open the filter without water pressure as the entire roof empties. Something like these...

Totally new to pool care and have been using a pool service for $50/mo. We decided to try DIY for at least a month. I was hoping for some money savings and to learn water chemistry better. If after the learning curve, the potential savings is small; then plan to return to pool service...
