For part one of this video:
Acid Start Up for White & Colored Plaster Pools Step by Step - Part one of two: • Acid Start Up for Whit...
In this video I bring up the pool from zero Alkalinity and a pH under 6.0 up to safe levels to start the pool pump and finish the start up process.
The problem is that there is no way to know where the pH is and how low the Alkalinity is as I bring things back up to safe levels. As I mention you can use thepoolcalculator.com but you are entering "start" numbers that are only guesses. For example you can enter 5.3 as the pH but it could be 5.5.
The Taylor Base Demand is also not going to help as it is too far down to register an accurate reading. In this pool it took 25 drops of base demand to get it to 7.2. The chart only goes to 10 drops.
So the best thing to do is use a combination of Soda Ash and Borax. 1.4 oz of Soda Ash will raise the Alkalinity by 1 ppm and of course raise the pH at the same time. So I add 5 lbs of Soda Ash to start bringing the pH and Alkalinity up. I then switch over to Borax which will raise the pH and keep the Alkalinity low.
So the Soda Ash raised the pH in this pool and the Alkalinity to 50-60 ppm. It was pretty close to 60 ppm with the final drop. Both the pH and Alkalinity will contin ue to rise daily in a new plaster pool so check it daily for the first week and add acid to bring both the pH and Alkalinity back down.
New plaster has a very high acid demand -- usually for the first 6 months. Then it tapers off a bit.
Not a very difficult process. If you go to high on the pH you can always lower it the next day by adding some acid. As long as you get the pool running right away the plaster will be fine. The key is to get the system started as soon as you can after the Acid Start up has finished.

Thanks for the videos. Keep up the good work!

Nice pool!!!

@miaolson7744 9 лет назад

The water sure looks nice and clear

@GregBoerner Год назад

all videos say to brush the sides of the pool...what about the bottom?? Thanks .. much-needed info...good job

@SPL Год назад

The bottom should be vacuumed weekly - a good suction side cleaner is what I recommend or a robotic pool cleaner.

@MajidPatriot-si7vx 9 лет назад

I will thank you.

@markf4328 9 лет назад

Thanks for your video's. On your acid start up video, was wondering what keeps the plaster dust out of the pool with the pump not running. I guess its the high percentage of acid that eats the dust? I am going to get my pool redone with a small stone plaster, I guess the start up would be similar? Again thanks for all your great videos. As a do it your selfer I appreciate all the info.

@SPL 9 лет назад

The plaster dust just disintegrates basically. In a traditional start-up the dust is everywhere including the filter. Although not without it's detractors, the Acid Start-Up produces the best results. There is also a lot less scaling on the walls as the dust doesn't settle there. Most builders now use this method as it is endorsed by the National Plaster Association.

What about if u have low calcium in ur fill water??? When do u add calcium?!

@michaelseebalac2544 8 лет назад

thank you for your 2 part videos here. my plaster team left a ring at the bottom of the pool from the acid startup so when I filled it this ring was highly visible and a lot lighter than the rest of the barbados colored plaster. after 0 alkalinity for 3 days it's looking perfect now and the color evened out nicely with some aggressive brushing. after adding a bag of baking soda to a 40kgal pool my alkalinity is at 40 and my phone went up to 8.3. I'm assuming no borax needed to bring the pH up since it looks like the baking soda did it? it is fresh plaster so maybe the plaster is contributing to the high ph? any help you can lend would be great. thanks again you saved me from complaining to my pool guy! :) I was able to take care of it myself. they didn't do the startup for me I had to do it on my own.

@SPL 8 лет назад

Glad you were able to save your plaster job. The pH will be high due to the new plaster. Keep adding acid to lower it down to 7.4. The Alkalinity at 40 ppm is low but it will be okay like that for a short time. Even with adding acid in a new plaster pool the Alkalinity should rise - unless your fill water has issues.

@dvdgnzlz25 6 лет назад

First of all, thank you for the great content you put out. I will be using this method on my next startup coming up this weekend. My only question is, why wait an additional 3 days to chlorinate the pool?

@SPL 6 лет назад

I was always taught not to add chlorine to plaster that is curing. It won't need it the first few days anyway. I never asked why -LOL

@dvdgnzlz25 6 лет назад

Swimming Pool Tips, Reviews & How To -MrDgvb1 Thanks! I won’t ask why, either. Lol I’ll trust the process.

@grapplerguy2007 2 года назад

It would be very hard to do this method in the middle of summer in texas , no? No chl or cya when 100 degrees out. About to tackle my second startup. I started slowly adding chl and cya day 3 . Also water was soft 40 ppm ch. So started adding ch day 2 slowly by diluting in 5 gallon buckets over several days . Not excedding 20 lb a day

@dvdgnzlz25 2 года назад

@@grapplerguy2007 I did learn that the hard way. One thing that helped me was making the switch from Orenda SC-1000 to Jacks magic for Metal and scale control. The orenda makes it really hard to bring the chlorine back up when it’s time.

@grapplerguy2007 2 года назад

@@dvdgnzlz25 alot guys have old school ways that " may " work yet still unadviseable. Acid diluted in water always most advisable. I hate to argue someones ways thats been doing pools 20 plus years but old habits hard to break.

@JuanMorales-ks4ll 6 лет назад

why was to yellow and how you test

@joshmcdermott1685 7 лет назад

For new plaster startup: Why do you suggest using soda ash first before Borate? If goal is to raise PH wouldn't less Borate be needed to adjust the PH up with Alkalinity at zero? Then once the PH is adjusted where you want it couldn't you slowly bring alkalinity up with baking soda? Must be a reason....

@SPL 7 лет назад

I did receive your email but was out all day. Basically you want to raise the pH up rapidly and Borax or the Easy pH you referred to in your email will do that without affecting the Alkalinity much. if you use soda Ash you will bring both up and if you use Baking Soda later the pH will also rise. With new plaster pools the Acid Demand will be high for the first 6 months so you will be adding a lot of acid over that time. The goal is to keep the pH and Alkalinity from getting too high to prevent scaling. Since Alkalinity is much harder to reduce when the pH is constantly drifting high it is better to keep the TA low after the Start-Up. And you do want to offer your services to the plaster as such - 5-6 days straight - brushing the pool each day. 30 days after that with a once a week visit to adjust the pH. Typically in So Cal you get $350-$400 for a start-up. And as to when to bring the pH up - when you no longer see any plaster dust - this can be as soon as 24 hours or in some cases it can take 48 hours. Once there is no more plaster dust start to bring the pH up rapidly so that you can run the pump.

what app did you use to get the right amount of chemicals to add?

@SPL 7 лет назад

You can get the App here: poolcalculator.com/

@XrpAndy 5 лет назад

Does the beautec need scrubbing ? And also you just used that whole bottle ?? No mixing Z????????

@SPL 5 лет назад

Just regular brushing at a Start Up. The brushing will mix it up in the water and when the pool tuns on the enzymes will be circulated.

@csim187 2 года назад

Do you have to replace the filter after acid startup? Wont the muriatic acid ruin the filter ?

@SPL 2 года назад

Negative since the pool is off until you bring the pH up.

@manuelquijano9127 2 года назад

Did you did any vacuum to remove any dust from the floor during the start up process?

@SPL 2 года назад

No, the acid start-up burns up all of the plaster dust.

@manuelquijano9127 2 года назад

@@SPL do you prefer the acid start up and how many days is safe to have that ph low? Or the Orenda start up? Thank you so much for this information is very helpful to me

@MajidPatriot-si7vx 9 лет назад

my brother made some mistake on his new plaster i saw discoloration i think he put chlorine and he jump in the pool in its third day i know is crazy but he did what we can do to get rid of the discoloration the plaster is same as your in this video

@SPL 9 лет назад

You will have to call the builder and have the plasterer come back and do what is called a "zero alkalinity treatment." The sooner the better. There is a good chance the damage can be reversed.
