advice?

[fiorano]

hey everyone,
so im shutting down my 125 for now. selling fish and rock and all that.
but im gonna keep a 29 gallon with a 20 gallon sump for my clown frogspawn etc. however i plan on getting back into the hobby when i move into a big enough place for a large tank again ( im moving to a conda probly thats why im shutting it down). i have 3 250 w halide pendants my bubble king 180, neptune aquacontroller among other things. basically my question is well all of this equipment still be worth using in 5 years? i guess if it works now itll still work then but im debating whether or not to sell it or just use my bk on my 29. i currently have my back up skimmer (rs135) running it right now which is already overkill lol. wow this turned into a vent session haha just kinda bummed about shutting down my tank.
anyway is it way to ridiculous to use my 180 on this tank? and should i save it for my next big tank or sell it? i like it because its way more set and forget than my 135.
thx for any advice!
