Hi, I recently begun dosing my 4 month old aquarium with Seachem Part 1 & 2 via a dosing unit that is adding the chemicals to my return pump chamber. All the levels in my tank seem fine but I've just noticed a lot of white 'spots' that have built up on a lot of the plastic surfaces in my sump (mainly on my heater and on the walls that separate the chambers). They are like tiny granules that I can remove with my fingernail so I can only presume they are something to do with the calcium or alkalinity that I'm adding. Is this normal? Is it an indication that somehow the chemicals are not mixing with the water sufficiently?
Any advice welcome!
Thanks
