OK -- remind me -- you need to SLAM? If so, lowering the pH is fine. Sorry.
That is the correct amount of acid. You can just guesstimate a quart out of the jug. Pour slowly at the return stream into the pool. Under estimate a little. No issue.
We don't use sandbags due to this exact reason.So we pulled our steps out today and I think it is the sandbags we put in our steps to hold them down. We put sandbags inside of another bag that holds them. We are going to get new sandbags. Do you think we can clean the bags that hold the sandbags?
Perfect, thank you!Since you are still during your SLAM, you should ideally be above SLAM level over night.
So, ideally you add enough bleach once it's dark to bring your FC above SLAM level, and after 30 mins of circulation you make your pre-OCLT FC-test.
You can't add any chlorine after that test.
In the morning before sunrise, you do your post-OCLT FC-test. Then you can add bleach again should you still be failing one of the criteria to end the SLAM.
Is it difficult to get the pipes out every year to remove the steps?We don't use sandbags due to this exact reason.
What we did is: Cut PVC pipe to the length required to sit inside bottom steps, glue a cap one side, fill with concrete (or gravel), glue 2nd cap on the other side. We have 3 of those tubes, reuse them every year, and have not trouble with algae under the steps any more.
No. We pull the ladder up half way, dive down and take them out one at a time. Same as if you would take out the sand bags. Our sandbags always developed some small hole & algae would start inside. With the pipes, they are completely sealed. No chance of algae ever!!! We have been using the same ones for 5 years now.Is it difficult to get the pipes out every year to remove the steps?
I didn’t realize I needed to stay above SLAM level. Pool Math tells me what to add to keep reaching FC 16 as my CC 0 and my CYA is 40. Should I try to be higher then 16?Something is still consuming your chlorine. 3ppm over night is too much, looks like you have to keep going. Make sure you really stay above slam level all the time.
