i'm using Kent Marine and Knop brands additieves and Red Sea test kits. My LFS just started selling Tropic Marin products, but prices for their products are higher. What can you say about the company? Are these better products? I just bought their Calcium test kit. As i was told it is very precise test kit. It showed me 46o. My Red Sea Ca test kit shows me 400 and my Hahen Ca test kit shows me 560. What test to trust??? <img src="graemlins//urrr.gif" border="0" alt="[urrr]" />
