    CO2 Setup

    Hello Folks. A few months ago I finished my pool and always wanting to experiment with automation, I pull the trigger on a Intellichem with CO2 system. Per recommendation on this forum I'm not using it for chlorine control but only for pH control. I'm not to concerned about the additional...

    Pool Platform & Safe Materials for Pool

    Recently I was looking into purchasing a swimming training platform to put into an existing fiberglass pool, to raise the floor for younger kids to go into a more shallow area of the pool (see image). Turns out they are rather expensive and I am wondering if I might build one myself. They...

    Chlorine gas released from hot tub water?

    Does anyone know how much chlorine is released from a hot tub as chlorine gas? Obviously, there are a number of variables here so we'll assume perfect water chemistry and FC level. Obviously, chlorine gas is 'suboptimal' for inhalation and I've always assumed (maybe incorrectly) that the level...

    SLAM complete--what's next

    Hey everyone! Finished my SLAM yesterday, CC is holding steady at 0.5 (All of my numbers are below, as of this morning) and passed the OCLT. What is the next focus? Is it to increase the pH into a more "neutral" value? I know that I need to just sit and wait for the FC to drop a bit, but can...

    FC won’t go up

    Hello all, let me preface this by saying I’m using test strips right now and some data from my local pool store. I know I’ll need to get a proper kit soon. I haven’t been able to get my FC levels up, they were showing 0.3 ppm when I tested at the pool store and I had combined chlorine of about...

    New to TFP (Kind of) Question about CH after Pool Refill (pool store didn't want to sale me anything!) and daily Chlorine loss

    I recently drained and filled my pool (3 weeks ago). The CH reading is 80ppm. I know that's low, but when I went to the pool store to get supplies, I was told not to worry about the CH as it would slowly rise over time. I thought it was odd that they didn't want to sale me anything, so I left...

    Chemistry Tests Look Good...is a SLAM required?

    We had our IG pool resurfaced in December and chemistry was balanced immediately after by our pool guy. I took over maintenance after a few weeks and was simply brushing, vacuuming, monitoring chlorine and pH levels until a couple of weeks ago. We had zero CYA because of the new water, so I...
