So when running a VS pump at low speed 400rpm to 1500rpm does the flow rate matter still? And if so to what extent? I know I will need to set the speed high enough so my SWG will create chlorine, and keep the in ground cleaning system circulating. Both the 3Hp and 1.5hp pumps will flow enough...

I am actually in the same boat at Praj82. My 1.5hp Hayward Northstar motor went out and I am shopping VS pumps. I was told to pay more attention to the flow rate for THD (ft. water) versus HP ratings on the pumps. So I know I need a pump that moves the water at least 52gpm but I cannot figure...

I did some more testing the other day at around 1pm. FC was 4.6ppm, CYA was at 30ppm. I tested the salt 3 separate times with my Taylor test kit and it read 3600, 3100, and 3400pm. So I guess the salt level is good. I added a gallon of natural chemistry's liquid CYA and this morning my CYA level...

This summer my pool has had almost zero issues with chemical balance, staining and algae. This summer in Phoenix has been some of the most consistent 115+ degree days ever recorded. I set my salt cell at 80% with a run time of 12hrs from 8pm to 8am this summer. FC at dawn (5am - 6am) 7ppm. FC at...

If it is not a suction side leak it could be the impeller. After your prime the system with water and you initially turn on the pump, does water splash inside the leaf basket indicating the impeller is spinning? Is the pump abnormally quite than usual due to no water movement? If this is the...

I am actually having the same issue. My CYA levels at the end of last summer going into the winter was at 60. Yesterday morning at 8am I tested my pool and my FC was 1.5 and CYA at 40. I have not back washed or swam in the pool yet this summer. At 6am this morning my FC was 3.2 and CYA remained...

One more thing, I have not had to clean my salt chlorinator for 1 year. I have checked it every 6 months and there was zero build up. I am assuming the build up is calcium, correct? If so, then why is it that the chlorinator does not get build up yet, the pool floor does? And the staining on the...

2 months ago I did an acid wash on my pool to remove the calcium deposits in my pebble tec. Refilled and balanced the pool water. I have high calcium at 390 mainly because of the city water that is high in calcium. I added 12 40lb bags of pool salt which brought up my salt level to 3600 (Pentair...

Haha, I figured once I read what I wrote. I am going to increase my CYA slowly to 50 and see what happens and how it effects my pool chemistry versus what it has been. Then push it to 70 if all goes well. Thanks for the help! :)

The Speed Stir is the only way to go. It helps test your pool water more efficiently.

So, what happens if I have to reduce TA by adding a higher than normal amount of acid? If the CYA is at 70 I can only reduce the PH so much before the water becomes too corrosive. And if the water Temp really plays that big of a roll in the sensitivity factor of adding acids how do I get around...

Morning, I am new to the forum I have some questions about water balance with Salt water pools. I have been playing with the Pool Math Guide and have been reading all the pool guide info supplied by the forum and I am kind of confused about a few things. Why is it recommended to keep a high...
