Angels Plus Sponge Filters are the most efficient sponge filters on the market. They are carefully designed for optimum flow rate and the ability to grow dense nitrifying bacteria colonies. Keep in mind that flow rate can be too fast for a sponge filter and a faster flow does not necessarily mean a better sponge filter. All sponge material is not created equal. Some contain mildewcides. Many have fire retardants on them. Others are simply made from a material that does not promote nitrifying bacteria growth. They may not kill your fish, but the beneficial bacteria, will not grow properly. Our sponge is chosen for it's suitability as a medium for nitrifying bacteria. We have tested dozens of sponge materials before choosing these. We've used them in our own hatcheries for almost 30 years. They have proven to be the best for raising our superb fish. We have sold over 100,000 of them since 1989 when we first started offering them to the public.

We use a clear lift tube, which is not only far more durable than needed, but it allows you to see into the tube to be sure nothing is clogging it and no fish has gone into it. The slate base is important because it is very heavy and fish-safe. Beware of filters using tile as a base. Tile is covered by a glaze which contains heavy metals. If this dissolves in your water, it can be toxic to your fish.

The LMS filter (Low Maintenance Sponge) is designed to decrease clogging and make cleaning easier. It has a larger pore size and the sponge is formed by a different manufacturing process. It is also a far more durable than the typical foam most use. We are still using some that are over 20 years old and still have the original sponge.

The regular pore Sponge Filter is most often used on tanks that have very small fry in them. It's possible that a few may get trapped in the larger pored LMS sponge. Typically any fry older than a week will be fine with the LMS sponge. This regular pore material will start to break down after about 3-4 years in the water, and needs to be replaced at that time for the filter to work at it's best.

The Active LMS Filters are taken from our tanks and contain a good colony of nitrifying bacteria. We put them in our tanks for 4-6 weeks, with the sole purpose of providing them to customers. This is a far superior way of starting a new tank, when compared to other bacteria starters.  Our tanks do contain snails and they are a likely passenger on these filters. Don't order them if you don't want the possibility of small snails emerging from them in your tanks.

The sponge is 4"x4"x4". The lift tube is 5.5"L x 5/8" dia.
The slate base is 4"x4"x1/4" - designed to be heavy, which holds the filter firmly to the bottom in bare-bottom tanks.

LMS Bio Media:  This product is the excess media from our sponge filter manufacturing process. We sell it below cost, which is a great deal for those who can use it. It's ideal for placing in canister filters, outside power filter boxes, box filters, and bio towers. It is very porous with tons of surface area, creating an idea media for culturing beneficial nitrifying bacteria. Each package contains a minimum of 230 cubic inches of LMS Bio Media (this amount fills a 1 gallon jar).
