The fact that your FC increased during the OCLT says there is a testing error on one end or the other, or your SWG is running. I'd make sure the SWG is off and do another test tonight.

To be completely honest, I don't know. This was just what I found in a quick Google search.

From the manual Resetting All Lights: To Reset all the lights you need to enter Party Mode four (4) times with less than 30 seconds between them. This will turn IntelliBrite Random Mode OFF. This is needed because should two lights ever get into different states, toggling their states will...

Have you used the CYA standard that came with your TF-100 to verify your test methodology? I was having very inconsistent readings on my CYA level, then used the standard to hone my method. Try different lighting, vial positioning, etc... I found that I had to shake the R-0013 bottle before...

So according to Pool Math I need 6 pucks to get my CYA back to my target of 40. This raises FC by 19, but I'm assuming this calculation is based on all the chlorine being available as soon as you drop the floater in the water. My understanding of pucks is that this is not the case, as they may...

Helps when I have my glasses on. Thank you.

My CYA has fallen from 40 to 30 and the previous home owner left a large bucket of 3" 98.6% dichlor tabs. I'd like to get these used up, and figured now would be an opportune time. My questions are how much total CYA will be added? I have no idea how much each puck weighs. Also, how much Cl...

Figured i should update since everyone seems to enjoy the green to clean pics. So this is where my water chemistry stands as of now. FC: 3.0 (27 minutes ago) CC: 0.0 (27 minutes ago) pH: 7.2 (27 minutes ago) TA: 140 (3...

You will not want to add DE until you are in the final stages of your SLAM. If you add this to a sand filter prior to killing/filtering out any appreciable amount of algae then you will have to backwash every hour or less. Backwashing also removes the DE from the sand filter.

That Anvil does look and sound sweet. Problem is I'm out of storage space and inherited the turkey fryer from my grandpa, so it's not going anywhere.

Running low on stock so had a poolside brew day yesterday.

Some of the big box stores will carry CYA (Clorox Stabilizer) during pool season. Muriatic acid can be found in most stores with paint section, and Borax will be found in the laundry detergent aisle.

I have 2 labs and have taught both of them to use the ladders to get out without any trouble. If you have a smaller dog, or an older dog, or an overweight dog, they may have problems. My 4.5 year old very athletic male has no issues. My 6.5 year old overweight female has a little more trouble.

Here are results from my test today. pH was taken with FC < 10 when I got home. FC: 15.5 (an hour ago) CC: 0.5 (an hour ago) pH: 7.5 (3 hours ago) TA: 150 (an hour ago) CH: 300 (an hour ago)...

I have put 90 degree elbows on both of my returns and they are pointed 45 degrees down and parellel with the walls. I think I have a fairly good circular rotation in the pool. I have resigned myself to the fact that I simply am not done with the SLAM yet, based on the attached photos. For the...

I have separate isolation valves for the skimmer and MD suctions. By "isolate to the main drain" are you saying close the skimmer or MD valve? I can read that either way.

I have been passing for the last several days, but I feel like I'm in the same place I was last time I tried to go to maintenance. I'm not willing to risk losing a week again if the consensus is that the pool is not ready for maintenance. My concern is that I thought I was done once before due...

I've been running DE for the last week when I can be around to babysit it. I can't add much, though. My clean filter pressure only runs at 3 psi, so according to the info I've read on here, I should be backwashing by the time I hit 4 psi. For adding DE, I'm supposed to add until I get a 1 psi...

Just wondering, am I done or is this still not clear enough to drop to maintenance mode? Running this single speed pump 24/7 has really taken a toll on my electric bill. I'm hoping to do another OCLT tonight along with CC in the morning, but based on results from the last few nights, I don't see...

Well that's not what I wanted to hear, but really want to get this pool in shape and do it right, so we will be continuing the SLAM. Thanks for the advice and reference. Seems like I still have a long road ahead...

Figured I should give an update on where I'm at. We passed our OCLT and CC requirements a week ago Friday night, but the water was still slightly cloudy. Figured this was due to the sand filter being slow to clear and went to maintenance mode. On Wednesday I started to notice the water clouding...

I'd recommend these as well. I use them to measure my sample, then transfer the water to the vials with painted lines that fit the speedstir better. This way I don't have to worry about if the painted lines fade, as mine have, and I've only been using them for 3 weeks...

Just running some quick math, I would guess you miscounted your drops on one of the measurements. If you truly had 11 ppm and added 2 quarts and 5 ounces of 12.5% Cl, then ended up with 22 ppm you are only treating 6000 gallons of water. I assume your pool is full to the 48" mark. If it is...

Update and questions. Got the new sand in the filter on Friday. FC levels only dropping around 2 ppm overnight and CC is down to 1 ppm. We can now see the main drain today. Now the question. My liner has pulled out of the track in a few places. I have watched some videos on how to tuck it back...

That's the plan. FC held steady at 16 from 2 until 4, then dropped to 14 ppm at the 10 pm test. CC is down to 1, and I'm starting to be able to see the vacuum head on the bottom of the deep end. Changing out the filter sand tomorrow as what I have is pretty coarse and round and I'm getting a...

User name goes back about 15 years from my old poker group. I'm proud to say that I earned that nickname and I use it for every login that I can. I don't know what I was doing wrong, but just did another test and got a reading of 40 ppm. Only thing I did differently was shake the R-13 before...

Yes

I must be doing something wrong, but can't figure out what it is. Just used the 50 ppm CYA standard to verify my test technique. The dot doesn't disappear until I hit the 20 ppm mark. I took a sample to the pool store (I know, I know) just to get a confirmatory reading before adding more...

Based on the filling logs, ammonia isn't making sense to me either. Unless I had some and now it's gone. I noticed the odor in the sand a couple days ago when I was checking the condition of the sand. Guess I will raise CYA again and continue with the slam.

The pool is continuing to clear. I can just see the bottom in the deep end now. I retested CYA today and got a reading of less than 20. Had raised it to 40 a couple days ago. Suspect that I'm fighting ammonia, as my sand in the filter has a slight ammonia odor. What is the recommended course of...
