Looking back at my first reef tank a couple years ago, a 29 gallon from petco with a HOB filter, a $10 heater and two $8 powerheads from Amazon.. This tank had no business even keeping the hardiest of fish alive! I had no idea what I was doing! How did I grow coralline all over the rocks, walls, and all equipment?? How did my corals not die, much less grow and spread!? I used straight tap water several times, did water changes every other month or so, thought the aiptasia and flatworms looked cool in the tank.. I took my water to get checked at a store once and my salinity was pushing 1.030.. But looking back, it is still one of my very favorite tanks I've ever had!! It got me into the hobby and I haven't looked back yet. Anyone else had an experience like this?? I'd love to hear it. I looked back yesterday afternoon through my phone and looked at some old videos and pictures of it.. I decided to make a quick video dedicated to the old tank on imovie.. Check it out!
