(Q) What kind of warranty/guarantee do you offer on livestock?

    (A) MemFish offers a 7 day guarantee on all fish (*with a few exceptions). If you should have a fish die, bring the fish, the original receipt, and a separate sample of water from your aquarium back to the store. Our staff will check the water to insure the water quality is acceptable - ammonia and nitrites are zero (0), and nitrates are 30 ppm or less. For salt water, specific gravity needs to be between 1.021 and 1.026. If these all check out, we will replace your fish, or get you something else for the same amount as the dead fish.

    MemFish does not offer a guarantee on invertebrates, corals, or live plants. Due to the sensitive nature of these items, we do not offer any type of guarantee/warranty.

(Q) What is your exchange/return policy?

    (A) MemFish offers a full refund within 30 days of purchase with the original receipt on all unopened items. We offer store credit within 30 days of purchase without receipt on unopened items. We have NO refund or exchange on opened items.

(Q) What is the nitrogen cycle?

    (A) The nitrogen cycle is a bacterial cycle that all aquariums must go through. When fish are introduced to the aquarium, they produce waste. That waste is broken down into different forms of nitrogen by beneficial bacteria in the aquarium. There are three main things we look for in the nitrogen cycle. Ammonia is the first, then nitrites, and finally nitrates. Once the aquarium has "cycled", you should not see the presence of ammonia or nitrites again. Nitrates are controlled by maintenance. Regular maintenance including partial water changes are required to keep the water chemistry healthy for your fish. Here is a diagram of the basics of the nitrogen cycle.
