Water from fish shops


Recommended Posts

Noticed that a few members are buying their water from fish shops.


Bear in mind that the Aquatic R.O. systems do not always have a DI stage, so the water may not be zero tds.


Bearing in mind that even a well maintained RO system can vary between 5 and 15 tds before the DI, and higher if the water pressure drops, or the filters need changing it is worth testing it for yourself before use, or using a DI filter before you use it.


Have seen these small DI filters that may not last long but can be refilled, and are nice and small to fit on a trolley somewhere. (In a van it is easier to use a bigger DI pressure vessel).

i thought you meant chippy's at first! would'nt fancy cleaning with brine.

untill i came on this forum i had no idea people bought their water, for me it'd be to much hassle going there and filling up. most folk say you can clean safely up to 10ppm, but i like to keep it below 3, but i've heard of it being used at 20+ ! probably depends on the glass?

I buy my water either from a large commercial cleaners locally £1.50 per 25l or if I need it in a hurry, an aquatics centre locally to me for £2.50. Never had to run it through DI as yet and no complaints of streaking so must just be a localised issue
