Re: Re: hydrometer dilemma


I have a model I bought from Premium Aquatics.......for $32 on
sale...........even though I had a BAusch & Lombe model with a price
tag of $1,500......I bought the el cheapo.....Now yopu may ask why I
would want a cheap one if I had such a nice high end one. The one I
have B & L model has interchanges slides for in it, so it can read
coolants, sugars, and a whole host of other liquids.......It was
missing the plate for salt. I bought it at a government DRMO sale
years back for $10 and it had the salt plate missing, but it was
unused, and like new......I eventually found a source for the plate I
was missing, and it cost me $40 plus S & H. I bumped the high end up
again the low end and both are dead on the money. Now thre B & L is
sure a sharp looking unit, polished nickle and real rubber or neoprene
handle, all fit inside a walnut wooden box that is lined in a velvety
looking material etc.where the import cheapo is probbaly die cast
metal and painted finish with a vynil type handle cover, that is in
sponge rubber na plastic box.. but bottom line is its perfectly fine
for saltwater aquaium use.
