I purchased some used BRS dosers off the for sale forums here on reef central about 6 months ago but haven't used them. When I got them I ran some RODI through them to make sure they worked and to see how much they were pumping per minute then put them in storage.
I am about to go on vacation so I thought now would be a good time to break them out and hook them up to my reef keeper but ran some RODI through them again to make sure the piping was clean. I tested the TDS of the collected water for both pumps and one came out to ~50 and the other was about ~17. I have the same pipes they came with hooked up to the dosers so Im guessing there could be residue two part in them that could be causing the TDS to rise.
I am going to change the hose and then check it again to see if I can get the TDS to drop but long story short do you think these are safe to use for 2 part?
