Good luck finding cheap LR
. Might want to look for some cold fire while you are looking.
If you want to save money build up your foundation with base rock and put LR
on top of it. Liveaquaria.com, fishsupply.com are good sources. If you use base rock you could always buy some top notch LR
with the money you save from LR
.com. Unfortunately there are temp out of business do to hurricanes.
