Evening all, almost ready to finish the 8ft cichlid tank, question is rather than have a 2 1/2 foot high pile of rocks what is the best way to build some sort of internal frame to create layers?, less rock required then. dimenssions are 8 x2.5 x2 ft or 240 x 750 x 600 if we talk cm. Like some do for reef tanks i assume?.
Thanks
