I also dose Warner Marine magnesium, strontium and potassium when needed. I also use the Warner Marine Ultimate Aminos, and soak dry food in their Huffa. I use prodibio w/ Zeovit Sponge power and coral vitalizer. I have see no difference since adding the Zeo products so I will not be buying them again. I must admit that I do forget to dose 1-2 days per week and that may be the problem.
On a side note, my bulbs are all 14 months old because I have put off changing them until i finally decide on my new lighting. I am still considering a Giesemann Spectra!
