Maybe I should ask what others are running in their tanks that contain lions or scorpions
i have a couple scorp tanks. my first is
standered 55 with
1 700gph aqueon
1 250gph mini aquion labeled for a bio cube for behind the rocks
Reef Dynamics INS-80 skimmer rates to 250gal
Life reef overflow 700gph
mag 9.5 return dialed back with ball valve
Eshopps sump
48" aquatice life t-5 HO 4 bulb fixture with built in timer
Fluval titanuim heater(300w)
this one houses
2 fuzzy lions
1 marine betta
1 ghost ribbon eel
another tank that is in the process of being upgraded. also is being used as a QT for the new tank 30gal tall
Eshopps PSK-75h skimmer rated to 75gal
1 850 korlia powerhead
coral life 24" PC bulb unit
Fluval titainum heater(150w i think)
this one currently houses
1 fuzzy dwarf lion
1 cockatoo waspfish
1 Fu man chu( just picked up yesterday! im ecxited!)
the tank that is replacing the one above 46 bow front
2 450 mini koralias
Reef octopus bh-1000 HOB skimmer rated to 90gal
36" aquaticlife 4 bulb t-5 HO with built in timer lights(i really liked the 48" so i got this on for this tank)
and of course just over 1lbs of rock per total gollonage of the tanks.
the 46 bow will have the tankmates of the 30gal in a couple weeks
so far all fish are a blast.
just as a heads up because i saw that you dont want to spend alot of money do not skimp on any major part of the tank cause you will just pay alot more later.
hope this helps
matt
