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.

Horrible infection improved in 3 day - day 5 - fish died? My black phantom had a really nasty fungal infection. After 3 days use the fuzz seems to have disappeared! No other fish have caught it and all of my plants seem perfectly healthy, the plants have actually reached the top of the tank while using. The photos show day 1,2 & 3 (as you can see day 2 it got a lot worse, i was worried but day 3 its all dropped off). Still an open wound so will keep using for the 7 days. Review: Amazing treatment - Amazing value for money! Alot cheaper than most pet stores and helped treated our fish and so far they are happy again.

There is a Pond version around simply called Pond Pimafix. **Q: I want the pond version of this but search just brings up pond melafix, is there a pond version of the primafix?** A: There is but it's rarely stocked by anyone - we never sell the Pond version of either. It's very common that people buy this version and then look up a dosage calculation online. **Q: How long does it take to work?** A: Visible improvement within 48 hrs. Problem kept reoccurring until we upgraded filtration. In the long term improvement in water quality is the answer rather than dosing with chemicals. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing!
