When are rock lifts necessary? I just read a little bit about them in another post and was curious about them.
What can be used as a rock lift?
Does the whole rock's weight need to be dispersed?
If you have any information at all, can you please post!
I've read a few threads 1st, but still unsure.
Rock is "holding" for existing established tank.
I just bought about 20# of totoka fresh in that day or day b4.
It has good coraline, pink, orange and green, a little plant life,
and some black junk, but not the soft black sponge that easily...
