I picked up a bag of this from Petco the other day and so far I can say i love it. It is much easier to use than the regular ol'cube food. It comes in small individual packages, so you can throw it in the sump to thaw it out a bit and rip the top open a feed as slow or fast as you want. I cant tell how much nitrates or phosphates it adding as I've started carbon dosing and i'm still trying to figure out the correct dosage but for ease of use I really like this product. Anyone else using this? or the mysis?
