  1. Hi friends. I have heard of products where displays and even alert us on PH drop or Nitrate drop etc. it's abit difficult to keep using the test kit every time to check if it's ok or not. What is the product to use to get the readings digitally with the computer software ? I am not any pro on this, just learning bit by bit. Thanks all.
  2. What I did was to paste two strips of blue LED on the current led lamp I have. Bought a step down voltage adapter (240v-12v) and it works.
