Actually If it is cycled, It's probobly ready for a pretty big load...I add a block of brine shrimp everyday...
All 60 lbs of live rock was being used in tanks that were set up with fish and all that. Along with the live sand for my sump that was being used in an established tank as well.
I have sponges on the bottomes of each of the power heads...The little shrimp gets stuck in there and I'm sure that is also where a lot of the benificial bacteria is growing.
Anywho, I'm going to see if I can find some RO
water tonight and do a good sized water change.
