if just using stress coat as a water conditioner, you use 5mls per ten gal and you add according to the total tank size not the water added...and if you are trying to use it as a healer for fins or other issues, 10ml's per 10 gals of water..stress coat+ adds more than just aloe, which replenishes slime coat which acts as a defense against invasion by bacterial, parasitic, and fungal diseases...it also helps reduce electrolyte loss which happens when fish discrete urine and poo even if not sick...its almost like a
calcium boost for them as far as the electrolyte loss...so a type of fish vitamin per say LOL ... prime works great also but doesnt have the added vitamin that the stress coat does..and its totally a personal choice for sure...
