For Sale: Pinpoint Calcium Monitor and Lifegard Fluidized Bed Filters


Recommended Posts

Hello Everyone,

I have the following for sale currently

Pinpoint Calcium Monitor ($125) - Used, I don't have any calibration fluid, here is a pic



Lifegard Fluidized Bed Filters ($20 and $40) - 300 and 600. 300 is 17" tall and works up to 300 gallon tank (comes with brand new sand). 600 is 27" tall and works up to 600 gallon tank (has sand in it currently).

Here is some info

Lifegard Fluidized Bed Filters

Three sizes available:


For Aquariums

up to 300 gallons.

For Aquariums

up to 600 gallons.

For Aquariums

up to 900 gallons.




In addition, the sand grains bump into each other frequently...knocking off excess debris and providing a self cleaning function which allows new areas for bacterial growth.The Lifegard Fluidized Bed Filterhas been tested and proven to supply the highest level of effluent water quality and will respond quickly and efficiently to severe changes in ammonia levels caused by over feeding or the addition of too many fish at one time. To obtain highest water quality...a Lifegard Fluidized Bed Filter should be part of the system.



Due to its unique shape, the Lifegard Fluidized Bed Filter is an extremely efficient...high capacity “biological” filter. Aquatic organisms excrete toxic ammonia as a metabolic waste product...with additional ammonia produced as food and other organic matter breaks down and decomposes. This toxic ammonia (NH3) is converted to another toxic compound nitrite (NO2) by the Nitrosomonas species of bacteria. The nitrite is then converted to a relatively non toxic compound called nitrate (NO3) by the Nitrobacter species of bacteria. This process is known as “nitrification”. A “biological” filter is a vessel where nitrification occurs and soluble waste is removed. Beneficial bacteria attach to the media within the Lifegard Fluidized Bed Filter... creating a thin film around the sand grains. Water is pumped up through the unit...lifting the sand into a “fluidized bed”. The beneficial bacteria attached to the media draw in dissolved wastes (ammonia and nitrite), oxygen supplied by Rainbow’s exclusive water fall device and other required nutrients from the passing water converting them to relatively harmless nitrate. The sand grains are in continual free fall through the water...resulting in an excellent transfer capability between the liquid and the bacterial film on the media. The enormously high surface area combined with this excellent transfer capability creates the perfect habitat for bacterial growth.

Spring loaded clamp creates a snug fit to any aquarium or reservoir tank. .CONTROL VALVE

Adjusts media level for maximum expansion of the filter bed and proper water flow. Prevents media from escaping and entering aquarium. Can be easily removed to add additional media.


Keeps media in place and allows for easy start up. External location for easy cleaning or replacement. Can be used in either the top or bottom inlet port. VERSATILITY

Inlet and outlet ports at the top for hang on aquarium installations.


Angular shaped media collide frequently, knocking off debris which creates new area for bacterial growth to occur. Enormous surface area for bacterial growth. Easily fluidized with a small power head pump. WATER FALL

Increases oxygen level by spreading out a thin sheet of gently falling water.


Heavy duty thick wall ABS molded parts. Built to last. CLEAR CHAMBER

Easy to view fluidization level at a glance.


Holds unit in place for installations below or beside the aquarium. DISTRIBUTION PLATE

Lifts the sand bed evenly and completely for perfect fluidization.


More capacity than any other make of equal height! VERSATILITY

Inlet ports on each side of the base for below tank installations. Use inlet ports on each side to connect multiple units together for any size installation.


Innovative design creates more filter volume area for increased capacity. Flat side for snug fit to any aquarium or reservoir tank. ADJUSTMENT SCREWS

Keeps unit level when installed in hanging position on aquarium or reservoir tank.


Plug off inlet ports not in use. Can be removed to drain or clean unit.



I also have a CurrentSea Wavemaker ($25) with plugins for 4 pumps (best wavemaker I have ever purchased, I am keeping one and selling my spare)
