my friend and i set up a 125 saltwater with a 55 gallon sump that is about half full. this morning i got a frantic call of him saying he can't even see through the tank because it is so green. the fish are not liking it he says.
last night he added 5 gallons of lava rack into the sump as bio media and but in a glass rock that was siliconed to a piece of acrylic that he suspects was not fully cured, though left for 6 weeks.the sand is that white home depot stuff that comes in 100 lb bags for 8 bucks. and on the bottom of the tank large black spotches are present which i would imagine are hydrogen sulfide.
my thoughts were that the sandbed does little filtration and has been continuously overloaded, he does have a tendency to overfeed, so it has finally just exploded. our game plan is to switch the sand for live sand, do a %50 water change, run carbon, andkeep the lights off. and of course the fish will be moved to another tank for all this.
any help would be great, thanks.
