This has nothing to do with the lower PH level. You need to follow the SLAM process and you'll need a quality test kit to do that. How are you testing your water? How have you been chlorinating the water? You'll want to order a good test kit. Read this: Test Kits Compared - Trouble Free...

Bought 2 gallons last night at Menards. $4.99 each (before 11% rebate), same price it has been for the past 3 years and the shelves were fully stocked.

I use a boat oar to mix. Then follow with my brush. Then drop in my dolphin for a round of vacuuming and that takes care of all the mixing I need.

Welcome to the forum. Many people have come here with your exact problem. I'm gonna ask you to invest just a little bit more. You need to get a good test kit. I have and recommend the TF100 from tftestkits.net. It will save you a ton of money over time, so think of it as an investment...

I am one of the people that posted one of the threads about Quikrete sand. See this post: What's the final word on the quikrete sand? I recently helped a friend of mine deep clean her sand filter and she had bought Quikrete sand thinking she would have to add some sand. I inspected the sand...

@Dadof6 - I'm curious how you got the CYA reading of 80.

How are you testing the water? Basically, if you have cloudy water you need to SLAM. See the SLAM article in Pool School - SLAM - Shock Level and Maintain - Trouble Free Pool Everything you need to do is outlined in that article. I'll summarize it. 1. Make sure you are testing the water...

32 oz of what concentration? According to PoolMath, 32 oz of 12.5% will raise FC by 2.8 in 11k gallons. That is probably ok under normal circumstances. However, you said your FC is 1 in the morning. CYA is 50. That is asking for a problem. You need to be following this chart: Chlorine /...

You can use plain old bleach. The generic stuff is sold at my local Menard's for $2.99/gal and it is 8.25%. Don't get bleach that has additives or is advertised as "splashless" or "chloromax" or anything like that. Just plain old bleach in the highest concentration you can find will work just...

A typical cartridge filter will filter anywhere between 5-20 microns. 20 microns is about the size of a white blood cell and not visible to the naked eye. Unless your filter is compromised in some obvious way, these particles are probably not returning to the pool through your filter. To...

56 oz. of CYA should have raised the level to roughly 40. So you should be targeting a SLAM level of 16 (use this chart - Chlorine / CYA Chart - Trouble Free Pool ) Use Muriatic Acid to lower PH to 7.2 to prepare for a SLAM. Let circulate for at least 30 minutes. Use bleach/liquid chlorine...

0. I misread the product.. My sincerest apologies, ol mighty Donldson. I'll shrink back into my corner now and let the professionals do their work.

You don’t want that Leslie’s product because it adds CYA while it’s adding chlorine. We don’t want that. Find the highest strength liquid chlorine/bleach available and use that.

I get muriatic acid at my local hardware store. 31.45% is the concentration I get. It's usually in the paint section. You can get CYA at walmart in small amounts. I usually get it in 25lb bags off of amazon. You can pick some up at a local pool store also, if you have one nearby. Don't...

Use PoolMath to calculate the amount of Muriatic Acid you need to lower your PH to 7.2, add that amount and circulate for about 30 minutes. Calculate the amount of CYA you need to add to get CYA from 20 to 30. Add that amount to an old sock or nylon and hang it in front of a return. Squeeze...

You need to SLAM, but that might be difficult given a CYA of 90. According to the FC/CYA chart : Chlorine / CYA Chart - Trouble Free Pool you will need to use liquid chlorine/bleach to get to a target of FC 35 and keep it there until you pass the SLAM criteria outlined here: SLAM - Shock Level...

Yep. As you already know, you'll want to make sure you keep FC in the target zone for 50, but it does make perfect sense to bump it up.

Yes, I went with the gas heater. I'd recommend a gas heater in our area because the water temps can get too low for a heat pump to be effective. If I had it to do over again, I'd go bigger than the one I currently have. Mine is 250k BTU and heats the water just fine, but I wish I had gone...

Absolutely. We love our pool and have not had a single regret. Have you picked a contractor, or are you self building?

It's possible that is DE, do you see any odd white streaks coming from the returns? Can you drop a little muriatic acid on some and tell us if it bubbles/fizzes?

You need to get into all the nooks and crannys where algae can hide and make sure those areas are clean. Ladders, light niches, etc. Scrub everything down and also make sure you are brushing the walls and floor each day. Keep at the SLAM. Also, it may not hurt to verify your CYA to ensure...

Unfortunately, that kit will not test for CYA, nor is it able to test Chlorine at levels > 5 ppm. In order to follow the pool care protocols that we follow, you'll need to have a test kit that can test CYA and a FAS/DPD chlorine test. Taylor K2006C and the TF100 kits are the only kits that...

I'm gonna extrapolate here. The baby is your test kit. The poop is R-0870. That is why it turned pink, to indicate that there is chlorine in the water.

I can only tell you my experience. I had a similar drip last spring after opening my pool. I had not lubed the o-ring after cleaning the filter for winterizing. After attempting to tighten the band several times, I broke it back down and cleaned the mating surface and lubed the O-Ring. The...

1. If it is a very slow leak, you'll be ok to run the system until your replacement arrives, if your pump is variable speed you could put it on a lower setting for the time being. Just enough flow to keep your SWG happy. 2. You'll lose some DE, but probably not all that much, unless you pull...

88 right now. The family wanted to swim on Easter, which is pretty uncommon this time of year in NE. Fired up the heater on Friday night and let it run all the way through to Sunday morning. On Sunday morning the water was at 94. Overshot because the water was warmer than the air, which...

In that case, it seems you are on a decent path. Just make sure you add bleach each day until the kit arrives. Once you have your kit, get us some test results to work with. If the CYA is over 100, you'll have to exchange some water to get it to a manageable level. But, we won't know until...

What test kit did you purchase? If you got the TF100 you should have it pretty quick. I'm leary of the 100 CYA right off the bat. If it was a fresh fill 3 weeks ago, your builder would have had to add quite a bit or the pool has been on a HIGH diet of dichlor/trichlor. The CYA test is the...

When was the last time you cleaned your filter? What was the clean pressure at that time running at that speed?

@YippeeSkippy I did that because the pool wasn't completely full and I wanted to have circulation going for a longer period of time before I ran my first set of tests. By priming the pump and pulling water only off of the main drain, I was able to have water circulating for about 30 minutes...
