    Using TF-100 kit and during the hottest part of the summer (July-Aug) getting Green Algae

    Guess the 93% pool water temp makes no difference? To determine the CYA I use a red tipped bottle in the TF-100 kit, fill up to the bottom of the label with water, then fill to the top of the label with R-0013 taylor solution, shake then start to fill the CYA view TUBE till I cannot see the...

    That makes since. Yes the R-0870 is a purple/brown color so it is probably bad. Does the pool temperature at 93% have anything to do with the chlorine lock?

    Ok I can do the SLAM process... I appreciate your help, still need to know what I have done wrong to get in this situation? I have kept the CL >4 PH around 7.5, and CYA at 40 all summer. Otherwise, there is something to the process requiring SLAM every summer. or is SLAM required every summer?

    Added 5 drops of R-0003 to the 10 ml water and R-0870 combination, and the color has a slight yellow tinge to it.

    I just went out to the pool. I put a heaping spoon full of R-0870 into the 10ml of pool water and it did not turn pink. I then tested the cl with the K-1000 test kit and it is reading >5. The PH just spiked from 7.5 this AM and now 8.2 so will add M acid.

    I usually do not do the FC test only the K-1000 basic test daily and keep the CL >4. I did the FC test because I knew there was a issue at hand. Additionally just tested the water temperature with a very accurate thermometer... it is 93 F. The chemical I am using for the CYA test is R-0013...

    Using TF-100 kit and during the hottest part of the summer (July-Aug) getting Green Algae

    I have been using the TF-100 kit and have been checking and maintaining daily the water chemistry. Last week the pool started getting green at the bottom and is steadily getting more green algae. Here is my current water chemistry. pH=7.4 (have kept it between 7.2 and 7.5), TA=100 (have kept...

    Replacing Pump/Filtration system for a 20,000 pool.

    Much respect for you guys. Thanks much for your good input. superhsd - ty bud! The electric motor died so I replaced it with a new Pentair 1 HP two speed motor for about $250. It is soooooo much better than the old pump. The high speed is powerful and pulls water better than the old pump...

    Replacing Pump/Filtration system for a 20,000 pool.

    The motor is surely not working anymore and will not stay spinning. Used a drill with a common bit to get it started but even when primed with water it will slow to a stop then just hum and start to show some smoke. So, I just ordered a 3/4 HP Pentair Dynamo 2 speed... more to come. Will have...

    Replacing Pump/Filtration system for a 20,000 pool.

    Thanks all for your good info. My old pump for some reason is still working... I thought it was burned up. Will keep it working till it dies, and when it does, a 2 speed pump and much larger sand filter are going in. :)

    Intermatic t 104 timer, yes will do. And 1 HP 2speed pentair Superflo. Yus. The pump, i think is using 120 V? It has a green and Black and copper wire attached to it. The breaker is double wide. I will measure it with my volt meter and find out.

    Replacing Pump/Filtration system for a 20,000 pool.

    Thanks you guys! Makes since for the 2 speed motor. I don't know much about how they operate. Do they have a clock/timer to turn off/on pump? Also motor is a 3/4 HP 3450 RPM Emmerson and filter is a Sand Tagelus TA40/400 rated at 40 GPM. Here is a picture of it... and the back cover is off...

    Replacing Pump/Filtration system for a 20,000 pool.

    Hi and thanks for your good reply mas985. The 35' of head was calculated by summing up the length of the 3 incoming pipes (2 skimmers and 1 main drain) into the pump from the pool and dividing that sum by 3. Your recommendation makes since. Most VS are 3 HP and seem to have too much power on...
