Review of Microbacter 7 by Brightwell Aquatics
I am keen to provide a comprehensive review of Microbacter 7 by Brightwell Aquatics, a product I have utilized extensively during numerous system startups and particularly during a recent challenge with dinoflagellates. Initially, I employed Microbacter 7 to facilitate the cycling process in multiple tanks: a 120-gallon mixed reef tank, a 60-gallon cube, a 40-gallon frag tank, and a 200-gallon frag setup. In each instance, I began with dry rock in the sump and biobricks sourced from various brands.
Following the manufacturer’s instructions, I dosed the media for a week in a brute trash container equipped with a heater and airstone to ensure optimal bacterial adhesion. Subsequently, I transferred the treated media to the sump and commenced system operation as planned. Without fail, within two weeks of introducing ammonia into the water, I observed the complete clearance of ammonia and nitrite cycles, with visible nitrates registering and ammonia and nitrite levels consistently at zero. I found this efficiency commendable and believe it significantly expedites the cycling process compared to traditional methods.
I am particularly averse to fish-in cycling due to the stress it imposes on the fish and the necessity of introducing fish that may not ideally suit the system’s long-term goals solely for cycling purposes. Initially, I administered Microbacter 7 at a dosage of 5 mL per 25 gallons of water, achieving successful results. Subsequently, over the following month, I reduced the dosage to 5 mL per 50 gallons twice a week.
I must also highlight that in the 200-gallon frag tank, I supplemented the Microbacter 7 treatment with Dr. Tim’s starter bacteria during the initial startup to enhance bacterial diversity. The outcomes have exceeded my expectations, and I wholeheartedly recommend this product to anyone seeking to conduct a fishless cycle using dry starting materials.
