Introduction

I’ve been raising fish for over 35 years and took a break in 2020. In July of 2024 I broke down and modified a 30 gallon freshwater water box to start a sps dominant tank but ended up with a mixed reef system. I’ve had two resets on the tank in 18 months but it has finally stabilized and growing coral.

Introduction

Started out as an IM 20g tank and found a to good of a deal on this reefer 170. Transferred everything over from the IM 20g April 9th 2026. Love zoas and shrooms along with a few lps especially chalices. It’s been through some neglected/rough patches but trying to get it back going into the right direction.
