Evolution Aqua Pure Aquarium Information

PURE Aquarium (for freshwater). Have you tried it yet?

Do you need an easy way to keep your aquarium crystal clear? Do you need help to maintain healthy water in your freshwater tropical aquarium? Do you need help to mature your filter when starting up your tank?

If so, you need PURE Aquarium from Evolution Aqua, the bacterial treatment that helps to achieve and maintain a healthy aquarium environment.

What is PURE Aquarium?

PURE Aquarium is a bacterial treatment for aquariums of all sizes. Inside every ball there are millions of live bacteria and enzymes. Once added to your aquarium, the bacteria and enzymes inside each ball will start to break down the ammonia and nitrite in your aquarium’s water. PURE Aquarium also breaks down organic waste, which is often the cause of poor water clarity. PURE Aquarium will leave your water crystal clear and healthy.

Regular use of PURE Aquarium will ensure that your fish live in a safe, healthy and crystal clear environment.

How to use PURE Aquarium?

We recommend that you use PURE Aquarium as part of your regular maintenance programme. You cannot overdose with PURE Aquarium.

• To maintain crystal clear, healthy water add 2 to 3 PURE Aquarium balls per 10 gallons of water once a week. Add the balls directly into your aquarium or inside the aquarium filter.

• If using PURE Aquarium for the first time or if your aquarium has clarity problems, add 5 to 10 balls per 25 gallons of water. When water clears, continue to use as described above.

Package contains approximately 50 balls.

PURE Aquarium can also be used when starting up a new tank, to help to mature your filter.

*Freshwater aquarium use ONLY!

Comments: Hi, I have used this for over 5 months,I was ordering it somewhere else and then saw the excellent price at Marine Depot. This product really works, since I have used this in my 3 tanks, goldfish, tropical and cicchlids tanks there has been excellent results, clear clean water, and no fish loss, the water perimeter is perfect and I do 25 to 50 percent water changes once a week. For those of you who have goldfish, you know how messy they can be...but I really love my goldfish and I know I am overstocked, So I do have 3 filters running in that tank, As I have said since using this Evolution Aqua, it has been so much easier. I will continue to use this product. Give it a try you will not be sorry !

Comments: There is not so much review regarding this product so I said to myself the heck with it let me try it, it is a really good product to be honest, I have a discus tank and I have been dealing with ammonia level in my tank and I've been doing constant water changes and everything (less feeding etc etc etc) I put 5-10 balls in my 55g tank compared my water test before and after (48 hrs) ammonia is 0ppm, water stays crystal clear, I even tried it on tank with all goldfish which always has that cloudy water even after water changes, after 24-48 hours it is clear, I only rate it 4 stars because I want to leave that slot for more improvement on this product.
