Hey guys. I'm not new, but a bit of a hard head. Just want to clarify as I'm battling a heck of bloom today. So according to the pool calculator I'm supposed to add 63 Oz of calling hypo to get my fc level to optimum level for clearing this bloom. However yesterday I did just that & being that...

Does anyone know what the difference is between these two cartridges? Not that I'm trying to be cheap, but I can find the 870s for a little lower cost. Most likely I'll replace my filters with what's in there, the 880s, I'd just like to know what the difference is.

This weekend I decided to pipe around my heater. I bought a couple of 2" x 2.5" three way valves, some PVC, some PVC primer, & PVC Cement. I followed the instructions as best I could, but obviously not good enough. I've got leaks. So without ruining these two expensive valves I just bought...

So let's say on a normal day my pool consumes 2 FC a day. That is a function of CYA & organics in my pool right? If I have a CYA content of 40 ppm, according to the chart, my target should be 5 ppm FC with a minimum of 3 ppm. If I were to shock my pool, get the FC up to 16 ppm, could I...

I don't understand it. When the pool was first installed last spring, the filter pressure would run a little of 10 psi in highspeed, 6 psi on low speed, and about 20 on the spa on high speed. For the last month or so, It's been getting higher & higher. I cleaned the filters a few weeks ago...

I appreciate this forum. I believe in BBB. However, Tri-chlor, Di-chlor, stabalizers, etc.. have been around for years.. decades even. Pool stores have also been around for quite some times as well as pool cleaning services. Some of these pool stores/cleaning services are & have been fairly...

I'm keeping the kids out of the pool because the water feels too cold to me. Ambient temp is in the mid to upper 80s. The pool thermometer says the water is 80 degrees. I even put it in my net, sunk it to the bottom of the pool & held it there for 10 minutes. When I pulled it up, it said 80...

So I've been fighting an algae problem for a couple of weeks now. As you know, part of the process includes cleaning my filter. I noticed some yellow spots on my filter, figured they were from some algae growth. I figured keeping my pool at shock levels would eventually kill that as well. So I...

So I figured I should go ahead & get my pool in shape. There's heavy algae build up in the pool, as I haven't been taking care of it for the last two months. I spent the morning going over my pool school notes, getting the ph in line, & made a run to the store to load up on bleach. According...

Is there a particular water temp that Algae will not grow?

I've got something going on in my pool, but I don't know what. I've got an 18,000 gallon cloud shaped pool with an attached 6' spa. I bought a TF-1000(?) test kit. I've got a Pentair Chlorinator that I use to keep the chlorine level between 5 & 7 ppm. With the amount of evaporation I am...

The dipper isn't a very accurate measuring device. Sometimes the powder is actually a small chunk or two. Sometimes a little extra powder gets dropped into the test container. And if I use the dipper to stir the mixture, well there is always a little extra on the dipper. Then the instructions...

Let's say my Ph is off the chart. Greater than 8. I added 2 gallons of muriatic acid this morning, around 11:00 am. I just retested, my Ph is still showing to be greater than 8. I also did the Acid demand test, 19 drops. I'm thinking something is not right. I dumped another gallon of...

Let's say I've decided on a 12 hour cycle, should I run it to take advantage of the night time hours, the daytime (sunlight) hours, or a mixture?

Hey guys, I've had my pool for a couple of months now, only been using it for a couple of weeks. The first weekend, everything worked fine, the heater heated & controlled the temp just fine. Last weekend, it would heat up, but after several minutes there would be a violent cavitation noise, and...

Is there a reason I should insist on two skimmers?

I've never owned/cared for a pool. Just trying to get a little more understanding. I understand the math involved in the FC/CYA ratio chart. But has anyone ever experimented with reducing the FC at a constant CYA to find the break over point of when CCs will start to form? For instance...

But for all you BBBers... where are you? how often are you adding chlorine during the hottest part of the summer? once a day? twice a week? 3 times a week? & what do you do when you go on vacation?

Has anyone ever done any other testing to prove our water is clean and safe, sanitized? can I take my pool water somewhere to have it tested for ecoli? not that I have a pool now, but in the future.

I know five people with SWCGs. Only one guy has complained about his pool not being maintenance free, and so far, we believe his issues are because of some impurity in his well water, which is what he used to fill his pool. One of the five guys converted his manual pool to a SWCG, and claims his...
