I purchased some corals and equipment from another hobbyist who was shutting down his tank. When i mentioned i was using Zeovit he gave my the KZ additives in the picture below. I am not sure how old these bottles are and there are no expiry/use by dates on them. Would any of the bottles be unsafe to use if they were past the expiry date?
Also, at the moment i am just using Zeo stones/media, ZeoBak, ZeoStart3, Zeo CoralSnow+ and Zeo Active Carbon. I dont know much about the bottles below. Would my system benefit from any of these additives?
My po4 is currently <0.03 but my no3 has crept up to 20ppm over the last month as i've introducing some new fish. I don't want to start dosing any of these bottles if they will cause my no3 or po4 to increase.
