okay, so I have a questions on brushes for a plaster pool. We purchased our home 10 years ago and replaced the filter about 5 years ago with a Pentair quad 100 DE . It works awesome and is really quite easy to clean. Our plaster has some patches that have chipped away (not alot but some) plus some bits that are rough on the walls. Right now we are fighting our first every yellow algae in just a few spots in the deep end and the spa. Literally they look like rust spots on the wall, I noticed while brushing that they are attached to the rough spots....is there a tool that can scrape off the rough spots or will that chip away the plaster? Should we be using a stainless steel brush and not a nylon brush?
I've read your algae removal and am waiting for my test kit to arrive so I can get started. Our pool is crystal clear right now and really has always been clear. I did bring a sample into Leslies while I wait for my own kit to arrive (FAS/Dpd test kit). Part of the reason I'm taking over the testing of the water is my wife had only used test strips and I found them impossible to read . So I bought on friday the Leslies 18-576 kit ) found out yesterday I need the FAS/DPD chlorine tester so I have bought that. Needed to find you guys a few days earlier.
The readings in read were from Leslie's yesterday mine were done with my Leslies made by taylor test kit the night before
here are my current readings.
FAC= 1 ( the night before my reading was 2) the week before with test strips it had all been 0 on chlorine
TAC=1 (the night before my reading was 2)
CH= 550 ( we've been told to drain our pool 25% to lower this) my test with the Leslies drop test I stopped at 50 drops as I thought I was doing it wrong, guess I should have kept going (San Diego does have high water my test showed our tap water at 170ppm ( i have the 18-576 leslie test kit) their test showed our tap water at 126ppm) same day test
TA=110 (mine was 130ppm) with drop test night before with the Leslie kit ( taylor kit made for Leslies)
ph 7.4 ( our ph had been super high the week before and I had been adding muriatic acid to get it in normal range) we only had test strips before which were impossible to read )
TDS =3000 ( I don't understand exactly what this is but I'm told it should be less than 2500) instructed to partially drain pool to lower
We have an in ground plaster pool put in around the mid 80's 25,000 gallons with a spa attached in ground at the shallow end. Our deep end is 9ft deep. Pool does have some spots that have grey etching (was told they are mineral deposits) pool is crystal clear at the moment and the only thing we are trying to deal with is the spots in the deep end and spa of the yellow algae.
We do use a liquid chlorine that we buy at home depot
Question: brush advice
2nd Question: once I get my FAS/DPD test kit figure out my true chlorine readings and then proceed with slamming ?
3rd question: is there a pool scraper to remove hard bits off side of pool
4th question: do we need to drain our pool to lower hardness and TDS?
I think this enough for my first post!!!
Thank you in advance for advice
