Dear All, I have a 45 gallon tank, due to lack of experience I lost some fish reecently. Hence I use Mineral water (Bisleri/Aquafina) etc to change 30% water every few days. my ammonia levels are under control at the moment and the fish seems good as well. My question is, whether I can use my normal tap water (which is high on the hardness front) by using Prime, dechlorinator? Can i add the water directly to the tank, then add these chemicals? or should i keep the water in a bucket, puth prime and dechlorinator in it, leave it for an hour then pour it in the tank??

using mineral water is getting expensive and cumbersome as it comes in small packets.

Thanks in advance

I personally add my very hard tap water straight into my aquarium after adding enough dechlorinator for the whole tank. So I dose the dechlorinator for 10 gallons even though I am only changing 2.5 gallons worth of water. I've had no issues doing that. Other people will say otherwise.

But the water hardness might be an issue depending on what fish you have.

I can see no reason you can't use your tap water unless you have fish that require softer water. I would do small water changes to begin with though so your fish can get used to it slowly. Maybe no more than 5 or 10% at a time.

Prime is a dechlorinator so there is no need to add both it and another product. If I were you I would add the Prime directly to the bucket you are using to fill the tank. There is no need to let it set for any length of time since the prime instantly makes the water safe. I personally think it is best to treat the water before adding it to the tank.

You can ask your local fish shop about your tap water and fish. For water changes, I always put the new water into a bucket and add conditioner first (even when the conditioner says instant), then add it to the fish tank. This also allows me to bring the bucket of water to the correct temp. prior to adding into the tank.

I've used Prime for a long time and never had any problems with it. Just be careful because it's more concentrated than most water conditioners.

When I started my fish room, I used the bucket brigade to siphon out water and to add replacement tap water back in. I treated for the volume in the bucket, and it worked fine. As I found the need for a more efficient method, I'd use the buckets to siphon out water, but filled them back up with a hose. Then I'd add Prime based on the water volume of the tank. I never had a problem.

I'm curious what your tap water readings are. Also, when you say your ammonia levels are under control, I'm not sure what that means. If the tank is cycled, the only reading that could mean under control is zero.

I use a python water changer to change out the water. I refill with tap water using the python. I add my Prime (I double dose) directly into the tank first, then add the tap water in.

I used a Python and added tap water directly dosing with Prime first and never had any issues. I did turn my filters off during the water change process to help ensure that BB wasn't accidentally killed with chlorinated water. I no longer worry about it as I use RO water exclusively now.

its not 100% cycled yet. Im doing partial water changes to keep the ammonia level low...it was 0.25ish last time i checked

Prime is a dechlorinator. You should put a 1/2 capful of prime in the tank, then add the tap water.

However, you said you've been using mineral water... which probably has no TDS at all... I'm guessing your Ph was really low. If your Kh is below 1 or 2, you likely had wild swings in Ph... adding tap water probably rapidly raised it a bunch...
They probably died from the shock of the Ph swing.

Prime is a declorinate as well as a amo blocker

I believe its not as strong as i suspected... also my filter stopped working, had to clean the filter media, which added to the problem as the bacteria was washed off..i did add liquid bacteria seperately

Oh that's a bummer. It's so hard first starting out, but with time and patience it will all work out. Stay asking questions, you will get threw.
