Hi everyone am building my 120gal new tank and today i hook up my 4 stage rodi unit brand crystal pro all cartridges filters carbon membrane di are all brand new, after flushing for about 10 mins, and i tested my product water with a tds meter and reading was at 7 tds so am i good to go at 7 tds, or do i need to aim at 0 tds? Tank will be a sps dominant start from frags.
