Next was the invisible
rock lift. I got the idea from Fly Guy.
I took a 1/4 inch thick piece of acrylic and had Lowes cut it to fit the bottom of the tank. I then drilled 5/8" holes for the
acrylic rods.
The rods were cut with a PVC ratchet cutter (which ruined the blade...yea, I know FLY GUY!!!

) but darn it was easy!!
The rods were glued in with Weld-On #16 solvent cement.
The whole assembly was placed in the tank and silly-coned down so no water will get under it and possibly create excess nitrates.
Its solid!
Before I glued them in, I sharpened the rods with an angle grinder. This keeps the rocks firmly placed.
