I spoke with someone at ProTeam who recommended I abide by the directions on the bottle and let FC drop to 1-3 ppm. He said you basically want as little chlorine in the pool as possible. I tested this morning and I was at 8 FC, but I am just above my current target range of 5-7 based on 40...

Here’s an update on how pool looks, looks very clear but bright green. Waiting for chlorine to come down before testing pH and starting Metal Magic treatment

No problem, thank you.

Just to update PSI has risen by 5% since adding the DE, so not as much as I anticipated but it is at least risen so I don't believe the filter has a problem. The Metal Magic has arrived and I was planning on when to add it. I passed the OCLT and pool clarity is very good besides being light...

Before I started the SLAM process I had to change the gasket of my multi port valve due to leaking from backwash line. I didn't mention that at first because I didn't think much of it but not sure if I am experiencing an issue from that. I felt the sand filter was functioning properly but I...

I added the DE to the sand filter through the skimmer following the directions from the site. However, after adding almost 2 cups of DE the PSI had barely increased. I don't believe I have an issue with the filter gauge since it goes to 0 when off and reads normal when filtering. Could I have...

Yes

I tested last night and this morning and both readings were at 19 FC and 0.5 CC. So I believe based on this I passed the OCLT and was thinking of letting the FC drop to normal levels and trying a metal sequestrant solution, since I have not had success with PolyFil unfortunately. In the...

I'll keep the PolyFil in there to see if it catches anything. I did order some Metal Magic because after SLAM is complete (and water clarity is perfect), I plan on bringing down the FC to around 3ppm (since that is the minimum per my CYA of 40) and adding 2 bottles of Metal Magic. I have used...

Just an update, the pool water clarity has improved but water is still a light green. I need to check my PolyFil to see if it has caught any more of the iron. My last post had the results through yesterday. I'll perform an OCLT at some point this weekend to confirm SLAM is complete. Will the...

Here’s what we’re looking at after running for a few days. Not sure if that is iron or something else? I also bought some DE to add to the sand filter. I will add some after passing OCLT. My question is since it will cause the PSI to increase fairly quickly and I’ll likely need to backwash...

Pool color has not changed much. Looks similar to my previous photos. I have not used copper containing chemicals in the pool, but just figured it could potentially be a metal contained the well water I suppose. I will get some DE to use for the sand filter to see if that helps with the...

Yes, I have kept the FC at SLAM level. I checked the PolyFil after a day of running the filter and it certainly caught a lot of bugs and debris but I did not notice any metal staining. I'll continue running the filter but any idea how long it typically takes for the PolyFil to catch the metal...

Here's the current setup with the PolyFil in the skimmer basket. Just wanted to make sure that was setup correctly. I added this morning so I'll check later on to see if any metal was absorbed by the PolyFil.

I ordered some PolyFil and it should be here tomorrow. In the meantime, I am continuing the SLAM process. While the pool is still green (assuming from the iron in the water), should I continue until it the water clarity is perfect before doing the OCLT? It is still somewhat cloudy near the...

That makes sense, I will try that approach.

I think you are probably right in regards to the iron. I've noticed some rust on my pump basket and vacuum. I did notice this last year as well but never had this problem. Maybe when I filled the pool up some more was added through the well water and it precipitated when I SLAMed the pool. I...

Yes, I plan on doing another round of vacuuming tomorrow morning. I am testing, replenishing FC and brushing the floor & walls each morning. My FC has been at least 20 each time I have tested over the past week which should be sufficient based on my CYA so I don't believe I am dipping below...

Yes, here are a few photos I took this evening. It’s been this way for about 2 weeks now. I’ll try and continue to get the remaining leaves out and continue brushing. I haven’t needed to backwash much which is interesting, so I’m not sure if it’s a water chemistry or filtration issue.

I can see the dot at 50 but not 40.

I retested the water this morning and made sure the water was at room temperature prior to testing CYA. I actually did not get a different reading with this method. I performed the test 4 times and got the same result each time. The black disappeared at 40, so I believe this would mean my CYA...

I retested the water and it was at 1 ppm CC. I did a CYA test and after re-reading the Pool School article on CYA, I realized that if the black dot disappears at 40, to count it as a reading of 50, so that was an error on my part. So my reading should actually be 50. I was in a bit of a rush...
