i guess its time to change the micron filter and carbon block !! water taste like a fresh water tank !! but my question is not sure if its time to change the di !! after reading the manual i still cant tell !! the top 1/3 is a orange color then it blends into an orange/blue,green in the other 1/3 and the last 1" or two is more of a greenish/blue !! is it better to change all 3 at the same time or can i wait till the whole di turns orange ??
