Thank you for your reply. So it sounds like brush x2 or more a day and once the finish looks the way we want then check hardness and if over 400 drain some and refill.

Thank you for the responses so quickly. Yeah I read the instructions for jacks #2 and seems straight forward. My only question is if the hardness level gets over 400, do you just drain to proper level and then refill and keep going or do you have to finish it then until it looks the way you want...

great thank you. I have had my pool for only 14 months but I had a scale breakout and want to remove it. Did you have trouble testing the FC after using #2? I hear the FC locks onto the nitrogen and takes a while to unbind. How did you rest for FC throughout the process? If I have PH test, FC...

So I have had my pool since Feb 2019 and ordered the Tf100 in May once I discovered this site. I’m about to be out of CYA regent. I have repurchased DPD powder x2 now and with the other kit I had prior had PH and ALK I used first. I noticed on the TF100 there are no dates of expiration. The...

how did the bath turn out? Did you experience a rough finish after? Any issues post bath? Any chance to post the process for me to view?

In this thread it appears the pump is turned off when the acid is added. Is this correct? My understanding is the acid is heavier than water and should be circulated throughout the process. With no heater shouldn’t the pump be fine to circulate 5 gallons of acid in a 14k gallon pool?

Curious if you’d decided to move forward with the process and how it turned out?

TF100 and yes however with Florida heat a majority of the year there is evaporation and an auto fill in addition to when it rains which is a lot and auto drain.

did you get the photos? I haven’t tried a puck on it but I did use the jacks magic test kit and it reacted and removed the sand like material instantly with their stain/scale remover.

Here is 5 photos I took in the morning as you can see it when the sun is just coming out. My vote is scale. The texture and feel and look matches the ebook description. I currently use the TF100

Well I was testing every two weeks only using the pool store results for a solid 3 to 3.5 months so I could only imagine the PH in the beginning with the fresh plaster hitting 8 and sitting there for a week or so before my next visit.

I did the -.30-.60 for 3-6 months already. I kept it at -.47 for a while and nothing changed. I’ll attempt agian now that it’s colder and easier to dip lower with the colder water. So I take it don’t add anything at this time and stay within the - CSI is the recommended course?

I appreciate the response however I’m 100% positive it’s not algae as I conducted a overnight test and slammed the pool to confirm the first go round. Passed all tests. It is scale from the first few months of not having a test kit and being a dumb beginner pool owner. Not following the...

I appreciate the response. It is not alegae as it has been there for months and have scrubbed the pool contiunious. In addition no CC are present which usually appear when algae is there. I believe the numbers you entered are wrong. As it appears at -.37 at 68 degrees but it has been more like...

I live in Orlando Fl and the temperature traditionally is always hot. I was able to experiment this summer as this is my first year with a pool and the usage of FC. I was able to use 1 puck per week and the use of liquid chlorine and not have any CYA rise (given the rain and auto drain) which...

Thank you kind sir!!!

So Friday I came home after being away for a little with the parents watching the house and had some algae. I slammed the pool that evening and with 40 CYA kept it at 16 or so for until this evening. The pool cleared up last night actually only after 24 hrs. My pump has been running 24/7. My...

Would be safe to assume I would only raise TA if my CSI index drops below -.30? 60 seems to be the cutoff for that. Below that it goes beyond -.30

Cal hypo: It would be Leslie’s powder plus. Just have to see how much I have to put in.

Yes I’m sorry, we have both an overflow and auto fill. So let me ask another question. Give the TA of the fill water, due to the PH rise it has been difficult to keep TA at 80 or 90. It usually decreases back down to 70/60 with two 1/2 cups of acid or so a week. In about two weeks it will...

I use 31.45 MA and yes I have an auto fill. The auto fill is what has drained a good deal of water plus the builder had to drain 20% because of an area under some rock formations we have that I didn’t like how it cured so they touched up a few areas with fresh plaster. We’re talking small...

My fill water has a PH of 6.8, TA of 120 and CH of 100. My TA right now is 70

Pool was finished being built second week of Feb. so 7 months old. I have turned off fountains (we have 3) no kids, but no screen so lots of Florida heat but no trees around so no leaves or organics.

So let’s walk through an example: if Its the evening of day 1 and I have zero FC (to make it simple)and I bring this to 3 for my CYA level of 40 and the pool has PH is 7.5. When I come back to the pool the next evening to check FC and it states 2 and PH is the same or slightly below 7.8. I...

So reading the pool school PDF off amazon and reading this site for better of a half a year I still have trouble understanding the FC and PH testing sced. Normally I test my FC twice to three times a week and PH twice. Usually Tuesday and Saturday. I normally only use liquid bleach however...
