I stopped doing water changes 6-7months ago, tank seems to be doing better than 6 months ago. I will occasionally use mb7 Just to mix it up a bit but I think its more of a carbon source and some rando bacto not sure it does much for much, it doest appear to hurt anything...what would the dosing regime for dinos be, does brightwell recommend mb7 for dinos? Idk, idts, but possibly, its questionable, so are the ingredients....
