Black Ranchu

Took a risk and bought them all… glad I did.  Not the best fish in the world but glad to have them in my collection.

Fluidized bed Aragonite Reactor

For hardness and pH maintenance. Use filtered water as you do not want the sand to become biological.

Aragamax is the product for a fluidized application. I also use this as a substrate as it is perfectly smooth and round and the fish love to pass it through their gills as they look for food. I put a fine layer on the bottom of my out door ponds too:

Florida Crushed Coral is the product I use in box filters or media baskets(make sure it's caribsea as you don't want real crushed coral as it only starts disolving around 7.2):

The Power of Fluidized Sand

The gravity fed glass bead fluidized bed biofilter was inoculated with 500 mls of biologically active fine grain quartz sand.  The 300 gallon monster fish system was running at 1 ppm ammonia.  With in minutes of inoculation the effluent of the sand filter was at 0 ppm.  Within two hours the ammonia was non-detectable.

The fine grain quarts segregates to the top of the glass beads.  The sand can been seen as a one inch band of tan across the top of the blue glass beads.

200 gallons per minute fluidized sand filter

Here is one of 4 large fluidized sand biofilter that I have at work.
They have 10 tons of sand per reactor for a surface are of 81 acres
and are capable of digesting 100 pounds of food per day. They have
ultra fine sand for total biofiltration in a single pass. We could
enlarge the sand to significantly increase the flow rate. Current
models are gettig 150 gpm out of a 42 inch diameter filter.
