Tap Safe is a water treatment product which is designed to remove harmful chlorine and heavy metals from tap water making it safe for goldfish tanks.
I know that I live in a hard water area so I when setting up my fish tank for the first time I decided it was best to use this to be safe rather than sorry. I was new to fish keeping so after a scan of the products on sale at Pets at Home, I bought a bottle of this Tap Safe as it seemed perfect for what I needed. It comes in a 100ml bottle and costs around £2. I have also bought it from an independent garden centre in the past so it is a widely available product.
In terms of effectiveness, this product is a little difficult to review. My fish seem happy and healthy but I have never tried a water change without using Tap Safe so I don't know if the fish would experience negative effects if I stopped using it or if it would make no difference at all. However, I am reluctant to try this - if it ain't broke, don't fix it! Tap water does indeed have chlorine and fluorine added to and I doubt fish like it very much so I am satisfied that Tap Safe is doing it's job properly.
The product is easy to use. It comes with a tiny pipette which can be used to measure very small amounts or you can use the cap to measure larger volumes. Alternatively you can pour it into a measuring jug of your own if you want. It comes with instructions which tell you how much water a pipette of cap can treat so you can work out how much is needed. It comes in bottles with safety caps on like cough medicine does which need to be pushed down at the same time as twisting to open. This suggests to me that the product is a chemical of some kind which children should not get hold of, however it irritates me that nowhere on the bottle does it say what the ingredients are or if it has chemical properties like being an irritant or not. Presumably is isn't otherwise this would be mentioned?
Please note that this product is best suited for small aquariums as as the entire 100ml product is only enough to treat 57 litres of water! I have a 28 litre tank so I can do 4 partial water changes and this will last a month. It does not seem to be available in a larger sized bottle. If you have a large tank then you may end up having to buy more than one bottle of Tap Safe. Even for smaller tanks like mine, this is not a particularly good long term option as I have discovered other products exist which are more concentrated and sold in bigger packs which will prove to be more economical in the long run.
So even though I am pleased with the product and as an occasional purchase it is not that expensive, it will definitely save money in the long run to buy a more concentrated equivalent. For this reason, when I finish using my existing Tap Safe, I am not going to use it any more, I going to switch to using something that goes a bit further. I rate it 4 stars.
