Remember Joejoe. all fish are $5 unless they are big ones, then they are $10. Corals are $6 - $12 depending on the colour, more colourful = more expensive! The equipment lasts forever so it is always a sound investment, regardless of cost, besides you can always sell it for what you paid for it, maybe more. As for the products you dose, they never run out if the same container just keeps getting refilled, they last forever...
But honestly... the joy reefing brings you is worth whatever you have to pay for it...priceless!
