Why is this discontinued

I've used this simple API Replacement Filter Cartridge for Tap Water for more than 20 years. It has served me well for my 55 gal marine aquarium. Where can I order this? I would buy in bulk just in case they discontinue for good. Thank you. Andy

Great time & $ saver

The filter in its system is such a money saver. In that you don't have to buy your water or spend any gas money to obtain it. Highly reccomend this item along with the filter system.

Tap water filter

API's tal water filter works very well to filter the chemicals out of normal tap water. If you are on a tight budget, pick one up. The only downfall for me is that the water where I am is crap and so I am only able to get about 40 gallons of filtered water before it's time to replace the filter cartridge. The replacement cartridges are pretty expensive so I will be investing in a RO/DI system soon.

Great product

This filter system really takes all the junk out of my water my tank has been very stable with very minimal fish loss since we started using this method of filtering our awful tap water. The only downside is maybe the cost of replacement filters but if you love your fish its well worth the cost.

tap water filter

this filter for me is the best on the market. no wasted water, very easy to use, just takes a little effort which a lot of people dont have these days. I DO 25% weekly water changes on my 75 gallon aquarium, which keeps the water very clean along with my 2 eheim 2217 canister filters. I can get up to 100 gallons out of one filter, and i live in nj. We have the worst water, out of the tap i have cloromines ammonia, nitrites and nitrates. This filter takes all this crap out of the water and makes it safe for my fish. I love this product joe h
