Base rock is a misused term...some places say Base rock when they mean base rock...which is a type of live rock, just not as porous, not as pretty, and its usually choked with sand from having been buried in an aquaculture site. Some use base rock when what they mean is DRY rock...which is just porous rock usually from a fossil reef inland that has never touched SW in our lifetime. It low grade in either case. If you are building a Fowlr or reef tank on a budget, ya cant beat it for price. Prefered use is the lowest lvl of your reef shelf or structure, being the load bearing stone, quite often out of site. Base rock rarely comes with any hitchhikers, and DRY rock will slow down the cycle time of your new tank to a crawl that will make a snail seem fast.
as for sump designs, dont bother. By the time ya buy the mats and return pump, filter mats, recut the pieces 2 or 3 times to get em to fight tight enough, ya could buy a Prefab...for a sump go with a prefab, name brand...that at least will have a warranty on parts.
The six line wrasse isnt very aggressive in my experience and will get along with most fish of semi aggressive temperment. the compatibility issue with this wrasse is, its death incarnate for many types of inverts. I got rid of mine after it pestered to death both my pepermint shrimp and ate so many of my snails that my algae got out of control....for a 6line, ya need a big tank, so the invert population can withstand his hunting.
i have had FANTASTIC experience both FW and SW fish with
