Hello, I've been reviewing the posts any have been unable to find an answer. What is the best goldfish food to use in AP system.
My system is about 2 months old, nicely cycled. Plants are showing yellowing leaves and lame growth on some plants. I believe I have an iron deficiency and will be addressing that with nutrients but figured I should be feeding my gold fish with premium food. Any suggestions? What would be the best/proven goldfish feed? Thank you in advance. :)
