Hey guys, I recently purchased this de-ionised water at my local super market as I am unable to go to my usual aquatics store to refill on DI water. I have checked the TDS and it is 20, I know this isn’t ideal and that the best is 0 but it’s all I am able to obtain for the next week/ couple days. I don’t really know a lot about Di water and was wondering if I would need to dechlorinate the water? Sorry if this sounds like a stupid question, just want the best for my fish please leave your advice/ opinions below )
