Custom Foam Filters for Aquariums
We will custom cut any of our foam sizes to meet your needs. Whether you want a foam filter/tank divider, pre-filter for a sump, a piece to fit your own homemade filter or a replacement foam for another manufacturer's filter, we'll cut it for you as long as it's a rectangular piece. Our reticulated foam has much greater surface area than the Matala style filter sheets. There is no better filter material for nitrifying bacteria made anywhere! Our foam is Made in the USA You can choose from: Custom Thickness: We can cut pieces thinner than our stock thicknesses, but they can't be too large. For instance, we can cut a 1" or 1/2" thick piece, but we are limited to around 12" or less on the width for these custom-thick pieces. Length can still be up to 48". This means we can cut dividers for 5 and 10 gallon tanks. This is ideal for starting out spawns. A 10 gallon tank is too large for the typical spawn to start out in, but a divided 10 with a filter-divider can be ideal. Minimum: On custom-thick pieces, the total thickness of the pieces must add up to Stock-Size. For instance, if you want a 1" thick piece and our next Stock-Size is 2" thick, then you must order 2 of them. Choose the "Custom thickness" option in the drop-down box and put the thickness in with the other measurements when giving them. If in doubt, place the order and we'll let you know if we can't do it. The cost is $0.049 per cubic inch plus $0.40 per piece. For example, if you want a 12" x 10" piece that is 2" thick, the cost will be Height x Width x Thickness (in inches) x .049 = $11.76 plus $.40 for a total of $12.16. This piece would have a huge 240 cubic inches of filtering material for a very low price. On custom-thickness pieces you have to round up to the next inch on the total thickness when figuring cost. For instance, a piece that is 10.5" x 8.5" x 1.75" is priced the same as a piece that is 10.5" x 8.5" x 2". If you order a number of custom-thick pieces that evenly divide into a Stock-Size, then you get to pay the exact cost without rounding up. Example - (2) 10.5" x 8.5" x 1.5" 15 ppi pieces can be figured at the exact measurements since we stock 3" thickness that can be sliced in half. Tip: When measuring tank width, it is usually better to err on the side of a bit too wide. If the piece is too narrow, the gap will allow water to pass through unfiltered on the side. A piece that is slightly too large, will compress to fit the space. We recommend adding at least 1/4" to the inside width, to make sure the foam fits tightly. We will be accurate to within +/- 1/8" on all cuts. If you need to cut a bit off a piece, a very sharp knife works well. Some find that an electric knife works the best. The videos below show an example of a couple configurations for custom foam filters. Filters like the one in the video are "super filters" in regard to their capacity to filter water. Huge canister filters don't even come close to these.
Angels Plus Foam Filters are the result of decades of experimentation and extensive testing. We use the finest waterproof reticulated foam available for bio filtration. Not all foams are suitable for nitrifying bacteria growth. Some are actually toxic while others just provide a poor environment for growth of these bacteria cultures. You cannot purchase a better filter foam anywhere from anyone. Foam Options: Our 15 and 20 PPI foam is a good all-around choice. Pore size is large enough to not clog readily, yet it still offers a very high surface area for generous nitrifying bacteria growth. The 15 PPI foam resists clogging best of all. They are very popular as whole-tank filters. The 40 PPI option is great for newly-hatched fry tanks or small species. If the fish waste is small, then these will remain unclogged for a long time. The pore size is also small enough to prevent fry from entering a pore and getting trapped. As the fish get to be approximately a week old and they produce more waste, the larger pore options may be more suitable. There are many foam filters on the market, but they are unlikely to be able to handle the kind of fish density seen in this video. The below 40 gallon tank has over 100 large angelfish in it and it filtered by only three of our 4" air-driven 20 PPI sponge filters.
