I think that would be a bit hard pressed, 30 for Jagged setup, 20 for tank, 6-8 for diffuser, few bucks for bubble counter, couple bucks for airline, 8-15 for drop checker.. I think it cost me just under 100. I honestly will make that back in about a month just from selling plant trimmings in SnS, the growth for my plants is almost unmanageable now lol.
Please don't be cheap and not get a drop checker, you will gas your livestock. I started off without one while it was being shipped, I thought ok 2 bubbles a second should be ok, few days later put the drop checker in..yep, YELLOW, too much..Im now about 1.5 or a lil less a second to keep it green both when the lights are off and on. Remember plants don't use C02 as much when lights are off so the levels go up.
