Step 1: Convince your next door neighbor to set up a Salt Water tank.
Step 2: Buy a rack of beer.
Step 3: Enjoy their tank through their windows while you drink beer and relax.
Step 4: Offer them a beer while they do Water changes
Step 5: Repeat Step 4 as desired.
in all seriousness, welcome, keeping reefs is frustrating sometimes, but very rewarding, i'll try to find some links online, but tell us a bit more about this tank:
some questions i have immediately before offering advice:
a) is this a 75g tank all by itself? is it drilled or have overflows? do you have a sump?
b) do you have the needed equipment? heaters/lights/pumps/salt/good water source, etc.
Regards,
