So i found one idea that may be best for me . . .
"I buy lava rock and large, pebbled rocks in bulk from places like Lowes or Home Depot. To clean the rocks, I bleach and boil them. Then using aquarium-safe silicone, I glue them all together in a way that creates caves, arches, or pillars. I let them dry and instantly! a new breeding territory!"
The only problem im having is the whole bleaching part. I thought it was a bad idea to use any kind of bleach on anything you will be ading to the tank?!
And btw, this is all going to be for a 30gal SW tank.
