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'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 ## Images ![Lustar – Hydro-Sponge V Filter for Aquariums up to 125 Gallons - Image 1](https://images-na.ssl-images-amazon.com/images/I/3165Alo9voL.jpg) ## 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/133543046-lustar-hydro-sponge-v-filter-for-aquariums-up-to-125](https://www.desertcart.hr/products/133543046-lustar-hydro-sponge-v-filter-for-aquariums-up-to-125) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-22*
