Same for me.....54 years old, started keeping fish when I was 8, then got a wife, started a reef tank, somehow kids invaded the house, and took a 15 year hiatus, due to lack of time and money. Now, kids finally almost gone, wife gone, so, I am also back in the game! Been about 2 months for me....a lot of plants, so no cycle, as it seems. Slowly adding life.....so far 15 Sakura, and two Pygmy Cories, 15 nerites. Soon to be adding more Sakura shrimp, more Pygmies, and some Oto's, thanks to Msjinkzd......eventually hope to drop in some CPD's into that 75.
Always been into the hi tech stuff, so, currently playing with CO2, liquid EI dosing, and LED lights. The biggest change I see over the years is lighting.
