Old Fertilizer

[michael]

I have some old Flourish plant fertilizer that is about a half a year old, its the Comprehensive Plant Supplement. It say on the bottle that it must be kept in the refrigerator after opening. My problem is that i have had it left out for a few months. Is it still ok to use?

Thanks

You shouldn't use plant fertilizers in your caudate tanks. It could be toxic to your animals.

Most aquatic plants are designed to live in environments with low amounts of nutrients, so fertilizer is not needed. They will get all they need from the defecation of your animals.
