look what i found about NYC Tap water

a little outdated, this chart is from 2007. what other levels besides the phosphates are bad for our aquariums and are there significant amounts in the NYC system?

 

also wouldnt the dissolved calcium/magnesium/alkalinity benefit our reefs?

 

with some further research i found the chart from 2010, same questions apply

 

maybe, if u removed the chlorine and phosphates

 

Technically, yes... if the levels are consistent and within range once mixed with salt mix. However, there is no way of removing all the bad impurities without removing the good as well.

 

Holly cow, look at all the crap in there... Aluminum, Chlorine, copper, fluoride, lead, phosphate, strontium, zinc, nitrate iorn etc... to name a few. While the ocean may contain some of these, most are toxic at higher levels. If they are in your salt and in your water, they can get to toxic levels quick and can accumulate, leading to really high levels. Using tap water in a reef is bad news.

 

No, they are in our salt. The proper levels are in your salt already. If you have it in your water and salt, it can raise to high levels which can be problematic. Also, saltwater can only hold so much, so, if they get too high they will just precipitate and clog up your pumps with, essentially, limestone deposits.

 

wasnt the plan on using it but just wanted to know about the tap water a little more, is the concentration that alarmingly high in some minerals compared to the average amount on the charts?

 

well thats no good, just figured this would be an interesting subject

 

Reefers have been discussing tap water for the decade that I've been in the hobby at least and I'm sure quite a bit longer. I suspect it isn't likely that there is anything particularly new on the subject. Never know though LOL.
