and water is flowing
it took 6 trucks to have it filled up 42000 liter (11100 gallon) abouts

Damn, damn, damn, damn!!! This came together insanely fast!! I can't wait to see where you go with this! You are living my dream!! I've always fantasized about turning a pool into a reef tank like you are doing. I can't believe you already have it filled! Congratulations! This is quite the accomplishment in terms of scale of speed at which this came together. I am absolutely stunned! You are my hero! :beers:

Thank you though, for sure for now, this will be set up as a fresh water system. Option is still open to maybe eventualy to switch it to a saltwater system
I just need a solution for the salt level control during the rain season here.
if anyone has any suggestions maybe?....

Are you using tap water? I can't imagine that's all RODI?

You need a large overflow capacity so that the salt doesn't exit the system. Then, it'll evaporate.
You need a measure of how much rain falls x surface area of the pool to calculate the drift in salinity.
If that's too much, you'll need to raise a tent-like greenhouse covering.

So here is a solution I thought up. I am an engineer but not a chemist so forgive me for not having done the calculations on salinity:
You keep a couple high grad salinity probes throughout the pool to keep track. You also keep a couple of tanks of highly salty water on standby. As the pool becomes diluted below a certain salinity (1.024) you pump in the highly salty water from the tanks to raise the salinity back.
This would also require having a way to keep the pool from overflowing with all the volume being pumped in to the system. It adds possible points of failure, but I can't think of a more graceful solution right now. I am sure that there are people on this site who could help with the math for figuring out how to program a controller based on maintaining a single salinity.

That's a good idea airforceaquaria. I wonder if you could add a high water float switch to the system that would pump out water when rain raises the water level. That could trigger the addition of salt water.
My system isn't nearly this big but I feel like it takes a lot to significantly change the salinity. What is the average rainfall you get in your location?

Well I am a military guy so I am all over and keep my tanks pretty small... far to small to need to worry about rain filling them up :lmao:
As for the float switch that was exactly my thought. You would be adding water with a significantly higher salt content while removing diluted volume. This should be able to raise the salinity fairly reliably without to many moving parts. I am not sure if you have access to reliable salinity probes or how reliable they really are as I have no experience. Hopefully others will chime in!

If the tank is fish only, I believe it is quite ok for fluctuations in salinity as salt water fishes can tolerate conditions known as hyposalinity for weeks at a time in treatment of ich. And the salinity in the ocean is not always constant. So temporary fluctuations in salinity are quite fine.
Looking at the average rainfall in Pattaya where you are located, the most challenging month is going to be in October where you get an average of 240mm of rainfall for that month. I know that monsoon downpours can drop up to 3-4" of rain in the span of a few hours at a time. I think 3-4" of rain water added to a pool with the depth of 4-5' is a small dilution to salinity. Hyposalinity condition is essentially adding the same volume of fresh water into that salt water pool, and I don't think you'd get 36-48" of rain overnight in Pattaya (though at times I'm sure you'd feel as if it was that!). What needs to be ensured is that the run-off from the surrounding deck and the roof of the house does not end up in the pool also in order to minimize the rain water's influence.
Lastly, you will need means of removing additional nitrates that come with the rain water. Bio balls as part of the filtration system should do nicely.
And being that you are so close to the ocean at Pattaya, you can get NSW for the pool. Looking at your client's house, I'd think he can afford getting someone to draw NSW from out in the ocean away from the beaches where pollution would be the highest.
good luck with your proposal!
Now what kind of fishes are you thinking of keeping in there?
