        			Hydro-Sponge V filters provide both mechanical and biological filtration. Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle. In addition, the Hydro-Sponge traps larger waste particles mechanically cleaning the water. Other sponge filters can&apos;t compare to the amount of water the Hydro Sponge can move with the one inch diameter lift tube. The sponge is held on a heavy base to keep the unit stable and the raised sponge design prevents dead space beneath. Ideal for use in hatcheries and breeding facilities. Hydro-Sponge filters can be operated with either and air pump and stone, or a suitable powerhead. The Hydro V is rated for aquariums up to 125 gallons.

## Features

- EASY CLEAN - Easy to clean, just rinse and squeeze in used aquarium water. Never use tap water HIGH VOLUME FLOW - One inch diameter lift tube allows for high volume water flow and allows use of power head without adapters PROPRIETARY SPONGE FOAM - Made from Proprietary Patented Sponge Foam for the highest mechanical debris capacity and bio capacity
- TRAPS WASTE - The Hydro-Sponge traps waste particles, mechanically cleaning the water without trapping baby fish VERTICAL OR HORIZONTAL - Can be used in the vertical or horizontal position. Heavier base with a raised bottom

## Customer Reviews

### ⭐⭐⭐⭐ Glad I switched to this Sponge!
            
*by C***0 on September 9, 2017*

This 125g sponge works great in my 55g tank. Overfiltering is the best way to go! For reference, this sponge is about the size of a large roll of toilet paper. It takes a day or 2 to stay sunk to bottom of tank, after squeezing water into it & keeping a brick on it overnight. It works great to get sand particles out of the water from filling the tank. I have since switched to gravel, but it helped me tremendously with settling the sand & using as a buffer when adding water to the tank during fill-ups. The sponge tends to lose shape after a few squeezes in used tank water during deeper cleaning. I do this about once a month when it gets too dirty. It does retain most of its shape. Add an airstone within the sponge core, to cut down on the big/loud bubbles. So far I am happy with it! I have bought different sizes from the same company & all work well. I had used internal filters previously & kept getting detritus worms.. 🤢 None of that with this sponge! So glad I made the switch! Bonus = it makes an extra place for small fish to hide under. Plecos & snails love to nosh on it, too! 😋
  

### ⭐⭐⭐⭐⭐ is perfect for my fish
            
*by K***S on September 16, 2017*

use with my fluval 406 in my 65 gallon tank. my water in my fish tank with 8 goldfish, is perfect for my fish.  Yes I know I have more than what's recommended for goldfish for my tank, but until it becomes an issue..they are happy and growing with my 7-10 water changes.  A month ago,  I waited over 2 weeks to do a water change because I was on vacation. Despite some algae (which I also credit to adding a bunch of plants  a week before  my vacation, and some plants did not take) my water test were completely normal for ammonia nitrites and nitrates. I don't hide the filter, I think it looks fine in my fish tank.
  

### ⭐ Not the PRO version...
            
*by S***H on February 8, 2017*

This is the old version of the Hydro-Sponge filter, not the PRO version, which comes with a vastly superior reticulated foam filter. Look elsewhere.
