Question RO/DI question

probibly a stupid question, but here goes. alot of what i read(especially on here)says to use ro/di watter.. my question is why, does the water treatment(to remove chlorine and heavy metals) not do the job. or how about letting your water set out for a day or 2 first. does that not reallly work. i come from the freshwater world, and that is how we done it. please explain the diffrence... thanks

you want the RO/DI to remove as much, if not everything from your water to make it as pure as possible. you dont want to introduce phosphates, nitrates, and a whole list of things that would be in your tap water. After getting your RO/DI water and your TDS ( total disolved solids ) reading is 0, or as close to it as you can obtain, 0 being the best, you add your selected salt mix which will return any WANTED minerals to your water to get them at proper levels to mimic sea water.

tap water conditioners will only remove chloromines, chlorines, ammonia but not everything else in your water. having nitrates and phosphates pumped into your water by using tap water will almost guarentee you an algae problem, this is why its best avoided from the start.

Well, the DI is the part that brings your TDS to 0, without it the RO membrane does not get it there. RO=98% pure, with DI= 99.9%
