Not sure if they're compatible. I run about 1.5L of rock, and I dose amino acids, coral vitalizer, Zeobak, Zeofood7 and Zeostart2.
Based on dosages from G. Alexander, I buy these about once a year. I forget to dose a lot too :)
Overall, it's a cost that I have to factor into my annual bills, but I have the nicest tank I've had in 12 years of reef keeping. Probably not all due to Zeo, but it helps.
You also can eliminate a couple of those supps, further reducing costs. Save up, buy once a year on boxing day.
