what is best source of water to fill your aquarium?

Use tap but please make sure your tank is cycled first. http://www.cichlid-forum.com/articles/fishless_cyc...

Also return the AmQuel Plus and get something that just neutralizes chlorine and chloramines. If you have a properly cycled tank then you should never have to use a chemical to remove the nitrate, nitrite and ammonia and the chemicals that do that can actually be bad for the fish.

Your current plan of letting it run for a few days then plants then fish won't work. You MUST cycle the tank properly or else you will kill a bunch of fish and the cycle should take about a month, unless you can get seed bacteria from someone elses tank then it will take like 2 weeks, maybe less.

Best Water For Aquarium

If your tap water is drinkable, then that's the best source, and cheapest source, of water for your tank.

I doubt the "removes" anything, it will merely neutralise the tap water, chlorine/chloramine will wipe out your bacterial colony once your tank has cycled, this is bad! And some tap water will have traces of metals in it too which will also be harmful, which these liquids remove.

As for the ammonia/nitrate/nitrite thing, it won't replace cycling your tank!

EDIT: Amquel does NOT instantly cycle a tank. It will take 2-6 weeks of you properly cycling the tank before it's safe for fish. Amquel merely attempts to mask ammonia but it's still not a stable tank until it's cycled!

You should cycle your tank naturally. Chemicals just make the water unstable and potentially deadly to your fish.

Tap water that is safe for human consumption plus a simple dechlor only is best. PH mostly matters with very sensitive species and the rest are ok if the water is ok for you to drink. Filtered and bottled water doesn't hae any natural buffers in it so chemicals from the air an contaminate it and cause the composition to shift rapidly and kill fish.

the only reason it would turn green is from too much light allowing or accellerating the growth of algae. I have never heard of it happening as quick as you describe unless the water you are putting in is aged. Water from a tap should be impossible to turn green for a while as it still has chlorine in it. the only opther explanation would be if the gravel has a lot of algae in it that becomes agitated due to the refilling of the tank.

your tap would be just fine. But make sure you use the chemical accordingly. And make sure to cycle your aquarium! Btw, what type of "stuff" do you got there? Such amazing "stuff" to remove nitrate, nitrite, ammonia, chlorine and chloramines all together!

DO NOT USE BOTTLED WATER!!!!!!!!!!!!!! go straight from the tap. tap water has chlorine in it but that stuff u bought will remove it. heres what to do fill the tank with the gravel u want to use 1lb per gallon then place ur plants decor and w.e else u want into the tank. from there u add water then take ur declorinator which is the stuff u spoke up and add the required amount per gallon. from there u let the tank sit for 24 hrs its basically starting the cycle at this point. then u can get 1 to 3 SMALL fish i suggest swordtails for tropical tanks or danios are also great cycle fish after 2 to 3 weeks if u haven't lost any of ur cycle fish then u can add 2 to 3 more small fish or 1 larger fish give it another 2 to 3 weeks and ur tank will be fully cycled now as to fish there are some rules in general u wanna go 1 inch of fish per gallon and u measure that by the fish's adult size not thier current size at purchase for instance the swordtails will grow 3 inchs as full grown adults so if u have 3 thats 9 inchs of fish in which case smallest tank u should have with a filter meant for that tank will be 10 gallons now u don't have to follow that rule i own 3 over stocked tanks but u just need to make sure u filterate them correctly and stay ontop of ur water levels.

Now back to y never to use bottled water bottle water is taken from some spring in nature then processed by boiling the water and distilling it the water then has all the contaminates removed and they add in sodium as well as other chemicals to make the water taste good that is why bottled water is more thist quenching then tap water is there is they add electrolites that are good for us but not for fish so please please please do not use bottled water unless it is store bought from a petstore for aquarium use which will generally have the benificial bacteria in the water needed for u fish already.

You should use tap water. It's cheapest and quickest, and is easily dechlorinated. Bottled water is boiled, distilled, nutrient-free... yuckiness. Not good for fish.

Before you fill it with fishes, it would be best if you keep the whole unit running.

Decontaminate it with what you bought... Anti-chlorine... etc etc.

After a week add 1 fish and 1 fish only. Buy a fan tail guppy for starters. if it last for a week. Its time to fill her up.

Filling an aquarium up with fishes is another thing to look up for...

Population and nitrate levels needs to be checked.

To keep Acidity down. Try adding plants. Not only does it look good. But also it helps both nitrate and acidity levels in proper level and helps the little fishy grow, that is if your guppy spawns...

Try searching Google for answers.

Hope i helped. :)

Use tap water.
