Using the same products or different ones
I have a few questions that I need help with.
1. If I'am using a Seachem product in my tank(Neutral regulator) and I test my water for ammonia, and use another product that is not from Seachem, will that affect the fish or should I stick to using all products for water treatment and medicating from 1 company?
2. How often should I test my water in my aquarium for ph level, ammonia, water hardness etc...?
Does Seachem offer any free samples of there products? If they do, where do I go or what do I fill out to recieve them? :)
