Colombo is a Dutch product
http://www.colombo.nl/ it was always aimed at fish keeping, since i'm in the netherlands i regularly encounter colombo products in the shop but didn't use any of them. I more consider them as a trademark buying products and retail them on with their own name. Since aquascaping is getting more popular they also launched a new product line more aimed toward planted tanks.. Last year i crossed the line and bought a bag of colombo flora base pro becuase of it's availability in the lfs since i'm dutch. But very soon had my regrets, it's very soft, much to light and after a while degrades into dust. For so far their stated research
they obviously didn't, it's just another product they did put their name on.
But i guess in todays world evrybody works with contractors and all kinda became just trademarks.. They all still claim to produce, they do, but no longer under their own roof all do in mainly foreign country contractors. Without us knowing we buy a lot identical products claiming to be different but still is the same product only with a diferent name.
Maybe a not so suitable example, but i experience it oftenly with another hobby of mine, i'm trying to maintain an oldtimer Mercedes Benz.. I took out a broken part 32 years ago made in Germany by SWF, a rather heavy aloy cased part, went to the MB dealer to order it. They came back with a plastic equivalent, the part i still had was taken out of production 25 years ago. The new flimzy plastic replacement part, came in a nice box printed as Genuine MB part with small lettering Made in Czech Republic.
So i'm actualy pimping my oldtimer Mercedes into a Skoda with new original mb replacement parts..
