Water testing is essential for a successful aquarium.
Perform your tests or monitor water conditions accurately and conveniently with a cost effective tester, meter or controller. A basic necessity for any aquarium is water. To insure your chances for a trouble free aquarium use a high quality Reverse Osmosis system for contaminate removal. An R.O. system will more than pay for itself with the purist water possible for drinking and aquarium use. If you are in the market for a superior marine fish or reef tank filter system, I highly recommend an AMT High Flow Filter System.
