Aquarium Advice Regular
Hi all, I have just checked the tds on my RO water from the lfs and it is reading 265ppm!! I have had the water for a while, does it deteriorate with time? Also I am testing it cold because I haven't yet started to heat it, does that affect the reading? I do get quite a lot of green hair algae and I lost 3 shrimp in a few days some weeks ago, could this be why? I always ask the lfs to check the reading when I buy the water and they assured me their membranes are checked regularly and that the tds was good. What should I do? I used another lfs which was further away and got another awful reading so I find myself in a difficult position because I don't really know where else I can go for my RO water. Any suggestions? PWC is overdue but I don't want to use bad water and make the problem worse! Thanks everyone
