Review on Instant Ocean BIO-Spira 100mL: Safeguard Your Marine Aquarium with Ease by Paul Rumambi

I will always use BIO spira when driving in a future marine aquarium. I dosed ammonia during the first fish free cycle in my newly installed 29 gallon saltwater tank after adding Bio-Spira and they responded immediately. My ammonia went to zero in 3 days, within a week nitrite went to zero with a hint of nitrate. I added fish and dosed some Prime to detox the remaining nitrates, although there were almost none. My fish have been happy and healthy for 2 years now.
