By Lustar

*Capable of moving more water than other sponge filters.

*One inch diameter lift tube allows use of power head without adapters

*Raised off bottom, no dead space.

*Heavier base.

*Can be used in the vertical or horizontal position.

*Easy to clean. Just rinse and squeeze in used aquarium water (never tap water).

*Made from Patented reticulated filter foam for higher flow rates and larger bacterial colonies, no other sponge filter compares!

*Extra sponges can be purchased and kept in the aquarium for quick bio-cycling of new aquariums, hospital tanks, or replacement of the old sponge when worn out

*The HydroSponge Filter provides both mechanical and biological filtration. Aerobic bacteria colonize the sponge providing a bacterial substrate to facilitate the nitrogen cycle.

*In addition, the Hydro-Sponge traps waste particles mechanically cleaning the water without trapping the baby fish.

*Excels as a small tank or bowl filter, especially for bettas which have fins that can get easily trapped in HOB or other filter intakes.

*Excels as a breeding filter, as baby (fry) are not trapped by sponge filters and the Hydro Sponge #1 Stackable allows for additional filtration and hiding places for fry

*Great Discus filter, angelfish filter, hospital filter, or back up filter. Even the Primary filter for larger aquariums (two #5 Hydro Sponge filters can easily handle a 75 gallon aquarium); also consider using Hydro Pond Filters in larger aquariums and sumps (see link below)


I have used these filters in Marine/ Reef aquariums (with live rock, generally in sumps ), with GREAT results!

Sponge Filter, air diffuser, tubing connection diagram Here is a diagram/picture showing how to connect an air diffuser to the bulls eye of a Hydro Sponge Filter. As well simple air line and lift tube connections.

Please click on this picture to enlarge for a better view

SET UP:
Rinse and squeeze the sponge under water and slip the sponge on the strainer. Directions for use with a air stone (optional): Connect air stone to the bottom of the bull's eye, then connect bull's eye to the top of the strainer. Then connect air line tubing to the bull’s eye on the sponge filter and the other end of the air line tubing to an air pump.

Suggestions for air pump applications:
*The sponge usually will try and float when new (it will gain more weight over a few weeks as beneficial nitrifying bacteria form), I often will brace the Sponge Filter with décor/rocks for at least the first few weeks.

*The optional air diffusers will slightly increase flow and lower water surface agitation, however they are not required for proper sponge filter function (when run with an air pump)

Directions for use with a power head: Attach the power head to the lift tube.
See picture to the left (click to enlarge)

Suggestions for power head applications;
*Often I secure the power head/sponge combination to the aquarium with décor/rocks (this also hides the sponge from view) as well as the suction holders available with most power heads.
*The Strainer attachment of the Via Aqua 480 can be further tightened to the cone shaped adapter by wrapping 4-5 windings of Teflon tape around the base of the strainer, than adding the cone adapter over the strainer and Teflon tape. After this forcing the cone shaped adapter firmly into the lift tube should result in a very tight fit.

MAINTENANCE:
Rinse the sponge with cool, running water weekly. Do not use hot or cold water as this will destroy the bacteria which colonize the sponge. Do not use soap or detergent when rinsing the sponge.

BASICS;
When your Sponge Filter is attached to an air pump, the rising column of air in the tube pulls water with it.
You can measure the water flow (which can be useful to know) by slightly tilting the filter with the top of the outflow just above the aquarium water line and timing the fill rate into a pitcher or gallon jug. If it fills the jug in 30 seconds, you multiply 2 times per minute times 60 or 120 gallons per hour. (See diagram upper right, click to enlarge)
You can also add an air stone to the end of your tubing in the outflow tube to produce more bubbles and more lift.
When attached to a power head, the pump pulls the water thru the sponge media.

Hydro Sponge Review from Renee (goldenpuon) from “Everything Aquatic”

”I thought I'd write a review of the Hydro Sponge filters I purchase from Carl a while back. The results are excellent too.

Better than any sponge filter I've ever owned. It picks up fish waste very well and now I have to do less than half the cleaning for my tank. I had a guppy tank I was cleaning every two days with a micro filter installed. Now I all I have to do is clean it every 1 1/2 weeks! The Hydro Sponge also creates a good amount of water disturbance with very few bubbles produced making it a great for providing oxygen for fish. Its quality is just as good, if not better than most power filters out there. It is also small and doesn't take up much space while providing a great place for beneficial bacteria to grow. This makes it much more useful than really any other filter for tanks with high ammonia, nitrites, and nitrates. It is also much less expensive than filters that require a carbon. All you have to do is replace the sponge every 6 months and it costs little more than a dollar while carbons in power filter must be changed at least every month each costs a few dollars. One of the best filters I've ever owned, I highly recommend it for aquariums of all sizes!

Hope you guys like my review. I'm not just pointing out the positives here, they really are true.”
