My reasoning is not based on the assumption of his TDS being zero which we do not know or any other assumption. TWP units vary so much from simply micron filters, charcoal filters, good ones, bad ones nothing to do with what I stated. I also do not have the facts for a cost comparison from his post such as size of unit, tank size, water changes, water quality…
He said his tank is ok, not good, not great. I’m simply saying a RO/DI unit IMO opinion is a much better unit for pure water and a tank will benefit from it. For your info, a RO/DI unit takes out more unwanted impurities then just the TDS. It is a generally accepted fact that to have a good / great reef tank a RO/DI unit is pretty much a must have investment.
We don’t even know if it’s a reef tank? I’m just saying that a RO/DI is better then a slap on your tap, make my water taste yummy, take out the big hunks of crap filter. Can you really debate that?
So anyhoo Yifan917 go get one they are a good investment IMO.
