a couple of things. for
SH make sure you cruse over to sea horses dot org. they are great people. All the info for
SH you need is over there.
putting
SH in the
fuge might be hard to pull of. Make sure the temp at the
fuge can stay at 74. this is warmer than most reefs so that can be a problem. Also it the 20 high is taler than the other tank I would keep them close together. if the hight is to great you will need a stronger pump. this might create to much flow threw the tank for
SH. also if the water is falling to fall it will be louder. plus if you lose power you would flood the tank because of the water in the
PVC. Drill the tank high in opposite corners. or opposite pains of class also at the top. put baffles in the
fuge to keep it from draining more than about 1/8 to 1/4 inch. If you are keeping
SH in it you need to keep the flow to the
fuge slow.
