The best way to keep your aquarium clean is to maintain good water quality. This will keep your fish strong and vibrant, as well as preventing disease. How Do I Maintain A Healthy Environment? It is important to test your aquarium water weekly to verify good quality in addition to a bi-weekly partial water change of no more than 25% to help reduce toxic buildup, remove debris the filter missed, and replenish the oxygen available to fish. How Do I Take Good Care Of My Aquarium? Feed & observe fish daily Test water quality weekly Change 25% water bi-weekly Restore your ecosystem monthly Feed Your Fish Daily Feed your fish twice daily only the amount of food they can eat in 2 to 3 minutes depending on the species. Some fish such as bottom feeders and algae eaters will need up to 30 minutes to 2 hours. Overfeeding & low quality nutrition cause unconsumed food and more excrement which cloud water and raise harmful ammonia levels, possibly leading to fish loss. Take time to observe fish and the water temperature to ensure they are active & healthy. Test Water Quality Weekly An aquarium is a closed environment and in order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. The 5 common water quality parameters are Ammonia, Nitrite, Nitrate, and pH - all of which may vary over time and all are invisible to the eye which is why it is important to test weekly with API MASTER TEST KITS or API 5-IN-1 TEST STRIPS. It is also a good time to add API STRESS ZYME to keep your aquarium & gravel clean. Change 25% Water Every 2 Weeks In a closed aquarium environment there are no natural rivers or streams to carry away debris and other waste materials. It is important to renew 25% of the aquarium water every two weeks. When you change the water, it is important to know that tap water contains chemicals that make it safe for us to drink but harmful for fish, therefore add a water conditioner such as API STRESS COAT. Restore Your Ecosystem Monthly It is important to change your filter media & clean gravel monthly, however in doing so it can disrupt the fragile ecosystem of your aquarium. Use API QUICK START to strengthen it with ‘beneficial’ nitrifying bacteria that will naturally consume toxic compounds and help prevent fish stress. Also recommended when starting a new aquarium or changing the water.

I usually put half the required amount directly into the filter (once I've clean it) and the rest in the tank itself. Its perfect for introducing new fish to the aquarium as well as when cleaning it out. **Q: How much quick start should i use when doing a water change? should i use dosage vs total water in the tank (30l) or water i am changing (7.5l) thx** A: As it's a partial water change; not servicing the filter itself; stick with the amount for the total capacity of the tank will be adequate. A little over will do no harm either, adding a little now & then will keep both the tank & filter up with its ideal bacteria levels to process the muck etc. Some with more money then sense will dump the whole bottle regardless. **Q: Can this be used to help cycle my new tank for my axolotls?** A: Yes **Q: Do you use this every time you change water** A: Hi yes you do . I mix about 10 caps in to cold water half filled bucket and stair it about leave it till water change the next day . Hope this helps you . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Superb products. *by M***S on 23 February 2026* Superb product. API is one of my resources for many of my aquarium essentials.
