Hello everyone, my Name is John and I have been off and on setting up saltwater aquariums over the years, I play guitar , build computers as a hobby and dab into reefing is my latest venture which is why I am here, I have been using the site to research things and learn what I can from you guys for a while now, and I finally decided it was time to sign up and get some help before I have serious issue's with my tanks. currently I am running a 120 gallon tank with a trigger systems sump and have copopods, a niger trigger , copperband butterfly, coral angel a few snails and a diamond goby a hammer coral and a couple zoanthids which i do not know the name of in the tank. also I have a 90 gal with a nice sized rabbit fish , sailfin tang, snails and a couple perculas and a banded shrimp in.
