Always wanted a reef tank had 55 gal saltwater yearssss ago came across a used RSM 130D for decent $ so scooped it up......I must of been drunk cause my god there is ALOT to this hobby. Legit most of my free time is researching online and watching youtube videos on reefing. Still need an ATO and cover for back to hide skimmer as the Tunze 9001 and intank media basket didn't work out for me that skimmer sucks (and I gave it over 5 weeks and still couldn't get it tuned in) my water level I keep on point I add RODI water daily water level indicator on this tank. For a 34 gal tank I'm thousands into it I can't fathom how people have those huge amazing reef tanks either rich or broke from spending all their $ on tank stuff. Wish I'd glued my rock work when I started tank cause still not happy with it just can't find those "perfect pcs" to complete the look I'm trying for.
