What storage container do you use to mix your salt? The neomarine salt heats up pretty high so maybe it’s breaking down your mixing container and whatever you had stored before may leach out when heated by the salts anhydrous reaction and making it precipitate out which can cause low alk. Meaning do you dump the salt all at once with water or do you sprinkle the salt lightly and mixing with a strong pump for circulation. Also I would recommend mixing it with cooler water vs warmer since the mix will get hot from the reaction. Reason why I don’t mix it warm is it will precipitate out too fast “heat up and dissolve at a faster rate making the chemical reaction change too rapid. I understand why the water heats up faster for the magnesium and strontium to dissolve quicker but that also means your soda ask or alk and calcium will react with each other.
As for phosphate in your source water you can run a cation ion di stage or my personal favorite spectrapure silicabuster Di which I think also binds with some incoming phosphate from your fresh water, I’d also check ro pressure and should be between 55 psi- 80 psi, higher the better if not add a booster pump I use a aquatic life booster buddy. Run dual chlormines carbon block from brs, and treat the new source water with some rowaphos in a reactor before mixing the salt and a little bit of prime for any chloramines that gets through the membrane. With my nsw mix batch from neomarine I would get 0.04 ppm which is where I am at currently. With 4 Di 4 carbon blocks and dual ro and a booster pump. I can go for a year without changing it out
I use a 13 gallon plastic trash can to mix my water, i only do 10 gallon wc every couple weeks on about 70 total water volume. I wiuld clean the container every time I make nsw mix. I would dump the salt mix into the water all at once and have a mj1200 to mix it, I dont check the temperature, I mix the water in garage so Im assuming the temperature gets pretty high during the summer. I will look into maybe springkling the salt and cooling down the water on my next batch. The water pressure is close to 80psf
I added a chloramine blaster add on I got from MD a while back, so now it has a dual cholarmine blaster/ carbon, I made some water today and tested 0.03 phosphate for now that is acceptable since I want to keep my phosphate around there anyway. I will look into the 3 stage DI in the future, though if I dont see any issues I will probably just stick with this RODI set up. If I understand that correctly with that much di and carbon you are still getting 0.04 phosphate?
