Just came home from work to a bottle of prime from the post man. I usually go through lots of water conditioner which is why I opted to get prime.

My tank is 350 litres so according to the instructions I need 2 x 5ml cap fills? Is this correct to treat 350 litres as it seems such a small amount.

I usually change 50% at a time but today I'm going to change 70% because I'm a day later than normal. Is 70% safe to change in one go?

Thanks

It depends on the level of chlorine or chloramine in your water. 1 cap of Prime removes approximately 0.8 mg/L ammonia, 1.2 mg/L chloramine, or 3.3 mg/L chlorine for 50 gallons of water. I use 2 caps per 50 gallons because I have 2.8 mg/L of chloramine in my water. Some water is even higher in chloramine ... up to 4ppm. You should contact your water company or look online for the annual report.

More information can be found on Prime's product page < www.seachem.com/Products/product_pages/Prime.html >. For your convenience, 1 ppm equates to 1mg/L.

EDIT: 70% water change is no problem if you're talking about oscars.

This is the reading from my water board for my area. It doesn't say anything regarding chlorine.

You are in the UK aren't you?The water board are normally quite helpful, why don't you just give them a ring and ask them straight, I'm sure that someone will be able to give you the answers you are looking for. I have a feeling, but I couldn't say for sure that there are limits on how much can cause the UK water board can add to the water.

I may not always be right, but I am always the BOSS :-)

I've just called my water board and they said the chlorine in my water should be 0.5 mg or less. Apparently the only time it'll rise above this is if there is work being carried out locally.

They informed me if I need the exact amount they they can send me a water quality report.

Thanks for the replies.

So after the 75% water change yesterday and double dosing with prime, I came home today to find my water cloudier than usual. I tested the water and surprised by the results.

Ammonia - 0.5 ppm
Nitrite - 0 ppm
Nitrate - 5-10 ppm

I have done another 50% water change tonight but what do you think caused the ammonia spike. 3 days ago i shut off the cycled filter for 30 minutes while I cleaned the tubes and impellar but left the meda and pads untouched. I added purigen to the new filter 2 days ago.

Did you remove something when you added the purigen?

Was the media submerged in water the whole time?

Nothing was removed from either filter and the media was left submerged in the canister.

The pipe work was filthy to the point it was restricting the flow of the filter so I cleaned them and the impellar.

Test your tap water for ammonia.
