    Pentair IntelliBrite 5G Defect

    Has anyone else tried AZ_MB’s mod with the copper plate on page 4? I’m preparing to do it. After years of a non functional Intellibrite (I got about a year out of it), I ordered a new board. I have already cut the copper and ordered the thermal paste. Just curious it anyone else has done it…...

    New pool owner in trouble

    That looks familiar to me. Check out the ascorbic acid treatment described in the metal staining section of pool scool. I did it an it worked very well. The trick is to keep the pH low (7.0-7.2). I find that when my cholorine levels get high- those stains can start to reappear- which tells...

    How much CYA do I have?

    A bit of follow-up. I replaced 20% of the water and took a sample back to Leslies to have the CYA checked. Still reads 100- but 'just barely.' Ok- that's as expected because I fear that I have a lot of CYA with the history of trichlor and dichlor in this pool. I got the TF-1000 test kit...

    How much CYA do I have?

    Flipping the skimmer valves shut seems to work. I'm in the process of taking out a foot of water... Don't know why I thinking of this approach a bit sooner. This should make faster headway on lowering my CYA! Oh- and the pool is a beautiful blue today. With my recent luck, the fill water...

    How much CYA do I have?

    I was just looking at my plumbing system to see what I would need to do to make a drain past the skimmers (1 foot in total). I have valves in parallel labeled 'drain', 'deep skimmer' and 'shallow skimmer' that are all in the open position. I closed the shallow skimmer just to test and it does...

    How much CYA do I have?

    This may be a 'dumb' question, but how much water can I take out before I refill. I obviously need to find a more efficient way to replace the water. The average depth is about 4 feet. Would it be reasonable to take it a foot down before adding new water? I assume I just need to turn the...

    How much CYA do I have?

    Oh yeah... last months water bill was for 19,000 gallons. I've got a spinkler system going twice a week but much of that I'm sure was pool water.

    How much CYA do I have?

    I bought a house with a pool last summer. My first pool, so I had the previous owner give me a tutorial. He used Trichlor pucks in the skimmers and shocked regularly with Dichlor. I took up this same regimen and didn't think too much about it. Frankly it was easy and aside from the occasion...
