I brought my pool water to local store to measure the salt level because my salt cell was saying it was low. Indeed my salt was on the low end - so I'll add more salt. Simple. But then she told me my total alkalinity was 21. TWENTY-ONE! I've never heard of pool water reading that low. I...

I've been taking care of my pool for years and algae is always sneaking up on me, regardless of how diligent I am about chemistry. When my pool gets overwhelmed with algae, I simply SLAM it and start over. I find that when I SLAM, the pool cleans up in days. So far I've had to SLAM it twice...

I own an in-ground pool which has a pump for the pool (inline with filter and SWG) which can be switched to run 4 jets in the pool with or without the gas heater. My other 8 jets use a separate pump system which merely circulates the spa. With our concern for efficiency these days, why does...

I switched over to SWG in my pool 13 years ago. But I remodeled it 7 years ago and it's taken a bit of toll on my nice travertine coping. I'm on my third salt cell (still going strong), but my SWG board went out. So, better late than never, I've decided this is a good time to trial a simple...

I've read for years on the BBB method, but I've had pretty good luck with a salt water generator pool. It does require a high use of acid, but it pretty much eliminates the need for storing chorine - which I really like. If I'm on it and watch things closely, I can get thru an entire year...

I've shocked my salt water pool with dichlor to 22 for 3 days. All mustard algae is gone and FC seem to be holding at less than 0.5 ppm overnight. Here's my results: FC 20 pH 7.2 TA 80 CYA 70 It's now been two days since my end of shock and I notice the FC levels appear to be...

I've seen a lot of postings about concerns about too high CYA levels when using chlorine products. I seem to have the opposite problem. I have a SWG and often times my CYA always tends to drift downwards thru the course of the year (more so in summer). So I find I need to add more...

I've got an older heater and filter that works great, but I bought all new equipment from the same manufacturer so as to make things work together more easily. So I'd like to sell or give away some of this older stuff to any TFP folks. Is there a place or post such stuff? Marc

Here's a good story. Today I just went to my local Leslie's Pool Supply to pick up some chemicals. I needed some liquid chorine (and acid) to shock my pool as I've accumulated some algae (that's another topic I'll probably post). Any ways, I asked for some standard bottles of liquid chorine...

I can tell we have a few dog lovers in this forum. I see there is a concern for dogs possibly drinking water treated with borates, but what about children? I have a 1 year-old and a 3 year-old that love to play in the pool. I understand that borates can cause kidney toxicity with ingestion...

I'd like to remove any unnecessary check valves (or use 2-1/2" inlets instead of 2" inlets) so as to improve my circulation flow rate. (I've already removed a few unnecessary 90's and the pool heater with dramatic results!) However, I've heard that check valves can cause a significant head...

I have a pebble-coated pool (about 24,000 gallons) and 2 skimmers and attached spa. I'm looking for a good suction-side cleaner that is cost effective. (Robotics are just too costly right now for my taste.) I like the idea of a moving drain (helps to better circulate the water by pulling the...

I have a 2-speed pump for my system circulation and it is shares the spa jets (4 jets) with another spa-only pump circuit (other 6 jets). At lo-speed (50 GPM) I noticed considerable air bubbles coming from my pool return lines. This is the funny thing. It doesn't seem to do this at hi-speed...

My understanding is that if you keep tight pool chemistry (i.e. "balanced water") and keep your pool pretty clean, your pool should not produce much (if any) algae formation. I just bought an elaborate DPD test kit because I was getting some algae again. I have a SWG on a 24,000 gallon...

So my suction gauge reads 9 in Hg, my filter gauge reads 17 PSI and my flowmeter reads 80 GPM using my 1.5HP Jandy Stealth pump for my system circulation. According to this: TDH = Hsuction + Hdischarge = (1.13x9) + (2.31x17) = 49.44 ft head So then I pull...

I'm really interested in going green by trying a Pentair Intelliflo pump to replace my Jandy stealth pumps. I also have an Goldline saltwater cell I've used for years which I love. Here are my two concerns: 1) I've been told my a local pool shop that these variable flow pumps at the very low...
