It’s Smart To Be Proactive!
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 & Fish?
- 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 with API Fish Food which contains nutritionally enhanced proteins, allowing for easy uptake of nutrients and maximum absorption, resulting in less excrement for clear, clean water. Only give the amount of food fish 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. Take time to observe fish and the water temperature to ensure they are active & healthy.

Keep your fish healthy and thriving by testing your aquarium water's pH regularly with easy-to-use API pH TEST KIT for freshwater aquariums. Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. pH is the measure of acidity of water, on a scale ranging from 0 to 14. A pH of 0 is the most acidic, while a pH of 14 is the most alkaline. Different geographies have different tap water conditions with different pH levels, while fish require a specific pH level to thrive. A pH of 7.0 is ideal when keeping a community aquarium containing a variety of tropical fish. Goldfish and livebearers prefer a pH of 7.5. Many Amazonian fish, like angelfish and neon tetras, prefer a pH of 6.5 to 6.8. Mollies and swordtails thrive at pH 7.2 to 7.5. API pH TEST KIT for freshwater aquariums test a wide range of pH levels from 6.0 to 9.0. Just dip a strip directly into your aquarium, and use the color-coded chart to determine if your water is safe or if adjustments are needed. Then follow the recommendations to treat the water – it's that simple!

As far as the test itself, freshwater ph testing kits never seemed very accurate in my opinion. I have a 65 gallon freshwater tank and the ph fluctuates way too wildly according to these tests. My tank is well established and I've had it for years.
After doing a little research, I came to find out I'm not the only one. Apparently most home test kits for ph aren't terribly accurate, which very minor things affecting the results.
I'm not going to give it a BAD review because I don't think the product is actually flawed, more that this method of testing ph for a tank is probably flawed. The biggest complaint I have is the test tubes being less durable than they should be.
For anyone with spending a lot of time and effort keeping the PH of the water under control, I would recommend chosing fish that can tolerate a wide range of PH levels and preferrably those that prefer the natural PH of the water at your house. There are plenty to choose from. If the sales person at the petshop is not helpful, you can always look up the info online first.
Am not criticizing in vain API PH kit, I have cross examined with different water parameters buffered to 7.0 using Seachem natural regulator but and the kit gave me 7.6, tested the same water with HANNA and BLUE PEN devices that showed 7.0 ph as expected.
I have bought 2 of these API PH kits and all same wrong results....SAD
