I've had a difficult spring with the pool after it turned green during an unanticipated 4-week trip out of town, and again for a week when the motor broke down while I was SLAMing my way out of the situation. While in the past I've mainly had algae growth on the walls, this time the pool floor...

So I acquired a used Magnetek 2HP B985 dual speed motor to replace a failed B855 on my 2HP Challenger pump. Some pics attached. The motor came attached to a pump and filter as shown in the pics. I'm having trouble removing the center screw on the impeller, which seems to be locked up by...

I have an AO Smith Centurion B855 2HP motor driving my Pentair pump. A couple of days ago, the pump stopped working. When I switch it on, there is a straining sound for 5-10 seconds after which it trips out. I am able to turn the shaft. I tried replacing the 30 mfd run capacitor to no avail, and...

Came home this evening and noticed my pump wasn't running while it was supposed to. I reset the breaker in our main circuit breaker box, and went back and started the pump. It began to strain for a few seconds and went quiet again, giving out a very slight burning smell. Any idea what might be...

We've had a hard freeze in Houston that started Friday night. My pump was set to its regular schedule of 8hrs during the day with 2 hrs for the booster. Today afternoon I noticed that the pump was running dry. I stopped it and cleared the skimmers and the pump filter basket, but no dice. Could...

I finally got around to cleaning my DE filter grids this past weekend, and had a couple of questions. One: the little strainer at the top of the manifold is pushed in and appeared full of DE. What is the purpose of that device? Second: when I started the pump after reassembly, I got air through...

With all the rain in Houston, our CYA levels have dropped to 20 or lower. Looking to bump it up to 30. What's the most cost-effective way to boost CYA? I'm not sure whether premixed liquid stabilizer would be a more cost-effective option than powder. If powder is the answer, is it OK to add it...

Fellow TFPers! I've been struggling all spring to keep algae off my pool walls. Have done a couple of SLAMs which helped temporarily, but take my eyes off the ball for a bit and it's back with a vengeance. I've been a bit delinquent on my end too, but seems like I need a Grand SLAM to get it...

Life got in the way these last couple of weeks and I ended up letting my pool go a bit. Bad timing, because it's springtime in Texas and with all the pollen and organics, it quickly got out of whack. A couple of days ago, I saw that one side of the pool had started getting a yellow green coat of...

TL;DR: Pool green on return from vacay, managed to get FC very high by mistake, CYA very low, what to do? So I returned from a 12-day vacay to a green pool. Prior to leaving, I cleaned and brushed the pool, emptied out the skimmers and the pool vac bag, and raised FC to shock levels (24ppm for...

So I've been using TFPC method for a couple of months now with great results. In the recent week, I've seen that although I've been maintaining FC, I'm seeing hints of algae growth. I've been able to brush the algae away and the problem seems to stay at bay for a day or two before I need to...

Hello all! So I am a recent convert to the TFP method and needed your help diagnosing some peculiar behavior I'm seeing with my DE filter (Pentair Nautilus FNS 60). Whenever I charge fresh DE after a backwash, I get some DE in my pool returns for a few days. I usually vacuum it up over a few...

My new SpeedStir indicated that my TA was actually 60 and not the 80 that I was getting previously. The TFP Pool School recommends TA of 70-90+ for plaster pools, while the TF-100 test kit suggests 100-120. Which of these ranges is correct? Sent from my iPhone using Tapatalk

I understand the TF-100 CYA test is a bit subjective, but anyone have tips to get reliable results? I, for one, tend to see a faint black dot for quite a while and wonder if I'm going way past and registering low CYA readings as a result. Second, I'm not sure about the protocol for shaking the...

So I got my new SpeedStir and found out my TA is actually 50 and not the 70+ I've been measuring manually [emoji19]. Where do you typically get your baking soda? Sent from my iPhone using Tapatalk

So I backwashed and recharged My filter with DE via the near skimmer yesterday. A couple of hours later, I drained the surface water to waste for a couple of minutes to lower CYA, and then switched the multiport back to the filter setting. As soon as I did that, I saw a puff of DE entering the...

Hi All - I'm a recent TFP convert and just SLAM'd my pool followed by treatment for mustard algae and its looking great. Will be headed out of town for 5 days. What's the best strategy to treat the pool to see me through the trip? My instinct is to boost the chlorine to shock level (25 ppm based...
