In a previous thread I asked if a FW ammonia test would/will work with SW. Yes or No?
I'll need to purchase SW tests seperatly here as FW dominates my local market. My LFS will proly tell me FW tests are just as good for SW. BUt I want to be sure,
What are the most vital INDIVIDALE tests I need to look for/at?
All input here will be appriciated.
Thanks
