1st reef tank was about 10 years ago and was more active on a more local reef forum. I made a reef reference app for iOS called PocketReef and admittedly came here to plug the app. In my defense, it was totally free and I gained not a cent from it. I did it to try and make things less confusing for newbie reefers, and to learn how to code. Anyway, this time I'll try and stick around. Cheers all. Arthur
