John what is this veo system that you are using? I have heard of it but know nothing about it. How do you check your Alk and Mag?

those and actually letting your tank mature and stabilize. I had minimal growth for months because everything was fresh. then one day BAM! things need time to mature.

hahaha... forgot about my line up... speaking of which, late for dosing! :lol:

if you havent had SW long I wouldnt consider coral frenzy as a fixer.Its just food which only helps healthy corals with polyp extention.try maintaining constant water parameters for a year steady and you wont have to dose anything.Master the basics first

Ok just answered my own question. Found test kits for Magnessiun, Alkalinity. Ca stands for Calcium I hope

I have test kits for Calcium, PH, Nitrate, Nitrite, Amonia & KH. What else should I be testing for?

All test's done on my 155 since it has been up have been on the number's.

Started 6 month ago with 2 - 65 gal. Up graded to 155 a couple of weeks ago. All water parameters have been spot on since start up. I have a $25,000 whole house RO system (live on acreage) that really helps, produce's water quality better them store bought water. You really don't know what you are drinking when you buy store bought water, lol, but I do.

sounds like you need to do a little research before you even worry about coral growth let alone alkalinity

Please do tell what I need to research on, every little bit helps
