I have an ASM G3 skimmer body with recirc mod($20), Phosphate reactor w media($20), Marine Life Aquatics CR-250 Calcium reactor with media and CO2 regulator($150).
I also have a 55g ($25) tank that I used as a holding tank and a 75g w stand that sprang a leak if anyone feels like resealing it. Take the 75 and stand for free.
Take it all for $200.
