i was once told that to build a tank it costs
$20 a gal. on the cheeper end all said and done
$50 a gal for the higher end equiptment all said and done

Im into my 120G for about 3 grand and i bought the MHs used
the skimmer used built my own stand built my own sump bought dead rock and dry sand.

tank was new sump tank was new the sump return and CL pumps were new and heaters were new.

i got all my PVC for plumbing at wholesale costs..

i have all of the equipment already from my old tank i have another skimmer so instead of buying a new crazy one i think ill just run 2 (rs 135 and bk mini 180) i got 3 mh 250 w pendants il make a stand out of steel or aluminum ... havent really looked into that much yet but ill get it to work. and pretty much all ill have to buy is a tank ... if i can get a temporary sump started to make the system circulate so everything can cycle and get used to its new homei'll make my 125 i have right now into a sump.
This might be a terrible idea so if it is let me know hahaha but for now its roughly what i want to do . and there is really good deals on canreef so thats most likely what ill end up doing for a tank thanks :)
