drain goes into a filter cup which just has some filter wool type stuff, then under that i put my gfo/carbon in there along with a mess of marinepure balls. then skimmer (went with fc-80, not a massive fan) then into fuge. somewhere under that mess of chaeto is a tupperware of miracle mud (not sure how great it is, i think i'm going to remove it soon) and a small airstone and the worlds tiniest powerhead. i felt like after adding the airstone under the chaeto, my chaeto growth took off. but it also coincided with a fuge light upgrade so that was probably more the cause. and the blue thing on the left is the same ato u have! i'm a big fan of the duetto xp, it's been going hard for 6 months and hasn't done me wrong yet. and of course a fan because i live in socal and it be hot!
the light fixture is just some random thing i found at homedepot. it was the only non aluminum one. and i hung it from a shower curtain thing lol, it's super sturdy surprisingly tho so i'm rolling with it. the bulb is just some white par38 light from amazon. word to the wise though.. don't hang your light too high like i did.. and grew algae everywhere.. including in my skimmer. lol
sorry i thought i perused the thread thoroughly and missed the equipment post, you're definitely working with the best stuff!
