2nd shipment received for 230 gal tank...I won't bore you with unending superlatives...suffice it to say that I would not hesitate to deal with TB again and would recommend them without hesitation. I mentioned (early on) when ordering that I intended to do a large tank with a "cave look." I don't know if Richard paid attention to that and kept it in mind or not but if he didn't he coincidentally sent me rock that one might swear I asked for by measurement. Soooooo...for anyone contemplating TB rock v. other LR, don't let the price scare you away...save your money...take your time...and do it right with TB LR.
