Remove ammonia from your aquarium with these ammonia neutralizing crystals.

White Diamond® Ammonia-Neutralizing Crystals are ideal for all freshwater aquariums and ponds.

White Diamond removes up to 4 times more deadly ammonia to keep water clean and fish-safe. It protects against sudden ammonia "spikes" and helps control the presence of ammonia...especially during the break-in period.

I need a media cartridge for the Penguin 150 Bio_Wheel Filter to put this into the 2nd slot of my filter canister. Where do I find this? Or what can I use in lieu of a stocking?

Asked by: NancyS
We do not make media containers that fit the 150. The only thing I know of are media bags made especially for this purpose. BREX

Should I use the Black Diamond Blend with my goldfish? I add add aquarium salt to their normal water 1tbs in 5 gal. I heard that salt affects zeolite and releases ammonia. If not what should I use?

Asked by: Joe D
The best way to control ammonia levels is to not overstock, and to do small partial water changes weekly or bi-weekly for a goldfish tank. We would also recommend http://www.marineland.com/Products/Food-and-Water-Care/Aquarium-Bacteria.aspx instead of zeolite in your situation. BREX

How do i add the ammonia neutralizing crystals? I have a 38 gal tank and have the Penguin Bio wheel 200 filter system.

Asked by: RoyM
There are a few different ways of doing this. With the Penguin filters, you can purchase a media container separately that fits into it. Here is a link to it on Pet Solutions: https://www.petsolutions.com/C/Aquarium-Filter-Cartridges/I/Marineland-Penguin-Filter-Cartridges.aspx?catargetid=520009670000581070&cadevice=c&gclid=CjwKEAiAlZDFBRCKncm67qihiHwSJABtoNIgqO5d4ouH2shsgCTUV00P_Pnf2l5JbHmjXnz53FHRMxoCUGfw_wcB. This would be the easiest method, just fill it, and slide it into the front slot of the filter system. Another option is to take the toe of a nylon stocking and pour it in there, then tie it off, and place it in the filter box. Use approximately one ounce or 1/4 cup. BREX
