Hi just introducing myself as I'm new. Been involved with the hobby for 25 years. Took a short break when kids were young but back into it now for about 3 years. I have a mixed reef(sps, lps and softies) 90 gal with 20 gal sump. Really like the hobby and how it has evolved over the years. I enjoy making my own equipment and currently finishing up a diy protein skimmer(counter current air driven) - designed from info obtained by Escobal.
