MicroBacter Start XLM is the professional, live, tank starting, nitrifying bioculture for cycling new marine fish and reef aquaria that has 15 times more LIVE non-pathogenic microbes and enzymes than any on the market. That amount will shift a new tank`s bio filtration into high gear, and will also increase the nitrification rate in established systems.Technical Background
MicroBacter Start XLM 15X is a highly concentrated, selective complex of live, extremely effective microbes and enzymes that rapidly reduces the concentrations of organic nitrogen, ammonia, and nitrite in marine and brackish ecosystems, leading to greatly improved water quality and much faster cycling. Use of MicroBacter Start XLM does not alleviate the requirement for regular partial water changes to help maintain proper concentrations of elements that are vital to long-term health and survival of aquarium inhabitants.Overview
Instructions & Guidelines
|Important:||First, use Brightwell Erase-Cl to completely remove chloramines and chlorine from tap water.
Chloramine and chlorine are lethal to the bacteria in this product and if not treated will
cause it to fail! Shake product vigorously immediately before using. Consult
BrightwellAquatics.com website for the latest information and cycle schedule! Add the
appropriate volume of MicroBacter Start XLM (see below) to the aquarium in an area of
high flow to promote dispersion. Do not use "live sand" or "dry seeded artificial
live rock" until cycling with this product is complete!
|To replace bacteria killed by extensive
cleaning of substrates and surfaces:
|Add 10 to 30 ml per 25 US-gallons (95 L) depending on perceived damage to filter bed, and
|To replace bacteria killed by medications:||Add 30 ml per 25 US-gallons (95 L) depending on perceived damage to filter bed. Then add 5 ml per
half hour until ammonia levels come down.
|To perform a Fishless Cycle:||Purchase a bottle of MicroBacter QuikCycl to use simultaneously with this product, MicroBacter Start XLM.
Fishless cycling requires both products to be used together. This product will provide the bacteria
and the QuikCycl will provide the nutrients.
|To provide ongoing biological stability
to a cycled aquarium:
|Switch to MicroBacter7 after tank is fully cycled and one week has elapsed. At that point you can
add Reef BioFuel and/or FaStart-M to provide proper nutrients for the MicroBacter7. This will
provide increased water clarity and contribute to the ongoing health and overall vigor of the
|Notes :||It is normal for clumps to form in the product and for the product and the aquarium to have an "earthy"
smell or smell "off" and for the aquarium water to become cloudy and the smell and cloudiness to
remain for many hours after using. This is due to the bacteria themselves and is an indication of
quality and is the reason it is necessary to shake product well immediately before using. Brightwell
recommends that you not use any other type of bacteria product until your cycle with this product is
complete. Do not use live sand or dry seeded artificial live rock. There are no dry bacteria species
that will be compatible with this nitrifying bacteria product! To do so will only lengthen the time
it takes to cycle!
|Storage :||Although product can withstand elevated temperatures for short periods of time, for best longevity and
highest potency, keep below 80°F and if possible, refrigerate at 50°F. Do not freeze! Freezing can
kill the bacteria.
