I’m a fairly new pool owner.. bought this house with a pool about 2 years ago and have had nothing but problems with keeping it up. I even had to drain it completely last year and refill.
I think one of the main problems is just age.. the house is about 20 years old and I’m thinking the pool was put in not long after that (it has retro dolphin tile lol).
So the issue this year is algae and I’m almost positive it’s mustard algae because it is so stubborn and keeps coming back. I’m guilty of testing my water at Leslie’s for the past couple years and just this past month have done their whole Algae free treatment (yellow out + 4lbs of shock every 12 hours + clean filters + clear aid and run pump another 48 hours) TWICE! And while I’m adding the 2nd round of shock on the 2nd treatment I see the mustard algae already coming back! It’s so frustrating! I can brush it off the walls but it always seems to come back a couple days (if that) later. I’ll post pics of it when it was really bad.
So I took to the internet and luckily found you guys and educated myself. I have my own Taylor 2006 test kit and have read the “Pool Bible” you guys have and have learned sooo much! I’ve also learned that there’s a lot more than just bad water chemistry going on with my pool.
Water is blue but super cloudy. I’m doing the SLAM process now where I’ve used about 14 gallons of 10% bleach in my pool the last 2 days. Today around 4pm as I was adding a couple more gallons of bleach (per pool math app), I noticed a little yellow algae growing under one of the return jets (AGAIN) and an area on the wall about a foot away from it, at the time my FC level was 7.
Doesn’t make any sense! The pump is running 24/7 and keep testing the water to make sure the Free Chlorine levels are high and they’re always all over the place.
My jets have bubbles coming out and the filter basket has bubbles under the cover so I think I’m taking in air somewhere. The filter gauge always reads zero but i don’t know if it’s a bad gauge or if there just isn’t any pressure in there because of the air it’s taking in. When I open the pressure relief valve very little air comes out and no water so I know the filter isn’t filling up. I just ordered a new gauge and seal anyways just to see. Should my pressure ever read 0 when the pump is on, even if the pump is taking in air somewhere? Why wouldn’t water come out of the pressure relief valve when opened? Would that have something to do with the air intake? My levels as of 8pm today were
FC- 13
CC-.4
CYA - 35 (if I’m doing it right.. the dot becomes blurry but I can still kind of see it until 35 and then I can’t see it at all.)
pH (before SLAM started) - 7.4
TA (before SLAM) - 150
CH (before SLAM) - 400
I know the last 2 are high but I wasn’t going to worry about them until the algae issue was resolved. Any advice would be greatly appreciated.. I’m losing my mind and am about to turn it into a half pipe ?
These pics are just to show what the algae USED to look like.. for a diagnosis. I was able to brush most of it off the walls and will post new pics of what it looks like now but the algae that started coming back today looked like this only a much smaller patch.
