just some pics.

[i have crabs]

the black grouper im not shure what kind he is,is about 9 " and eats every thing you throw at him ,the leaflip/clown grouper is about 7" and i have to hand fed him or the black one steals it every time.
thier is only 1 tank with corals (wil be 2 with the nano soon) wich i have to keep up on additives and matinence stuff the others are just using aquaclear 500's and hob skimmers so its not that bad,
as far as waterchanges go i have so much rock in the 60g coral tank i only do them every 4-6 weeks unless i have to sooner for nitrates and i usally only do it them just for the heck of it ,the qt ,crab tank and baby tank never need it either cause thier is barley anything in them execpt rock.
the 130 with the groupers i do 20-25g every 2-3 weeks but i just added 100lbs of carib sea reef rocks and reef bones on top of the 60 lbs of live rock i had so hopefully it will cut down on changes too.
even with all that i still go through close to a bucket of salt every 6 weeks or so.
i only tell the wife about every 3rd bucket so it keeps her from bein mad about the money issue.
