AquamidasFreshaTank Water Tank Cleaner, Toilet and Waterbutt Treatment Freshener

Seems pricey, and they look a bit cheap. I was disappointed that its just a piece of plastic covered in silver so I was very sceptical. However, they really do work!We recently fitted a water butt, and the following day after an overnight shower I went to fill a jug from the butt. It was completely green and looked a bit rank.I ordered 2 of these, drained the water from the butt, dropped them in and waited for the next shower. The following day I took a sample and it was CRYSTAL clear. Opened the lid of the butt and it looked like fresh water. Can't say any more than that. I'd order again, and will when I buy a second water butt

I have one of these in each of my three waterbutts, and they do a superb job of keeping the water fresh. Any bits of moss or whatever which come down off the roof into the butts are precipitated to the bottom, below the level of the tap, so there is no problem with the gunk fouling the tap. A really excellent product.

I admit I was a little sceptical when I bought two of these last year. However they have kept my water butts clear of murk so to buy two more when I added more butts was a no-brainier. They are not cheap but that they work is more important.

good price,

I'm unsure as to whether it works, although I will give it time and see if I see results and will update my review in a month or two. Updating my review I do seem to see a difference with this in the tank the water quality is crystal clear and looks very fresh. and the glass is spotless no silt, however for the germ free and low risk of parasites etc I'm not so sure about that because my fish developed white spot and I lost quite a few of them to this I have treated the fish and they are back to normal now but I have taken this out for the time being I'm not blaming this for the white spot but I am pointing out that although it says it can eliminate parasites/germs and help prevent fish disease well this is obviously in my case not true.

I love these products. They really do work. Particularly the flower disc of which I now have three.However after checking with the supplier I could use this particular product in our garden birdbath (the answer was yes)I found that the birds wouldn't go to the water, flying away when they clearly saw the shiny object as a threat?Has anyone else found this problem? I will try again, but in the meantime I have one in the granite fountain we have and it seems to works a treat although it is early days yet. I did give the fountain a good clean and scrub first as it was a bit slimy after the winter andsome garden renovation work had been completed.

I use for dropping into IBC full of water and it stops water and the IBC from turning green, drinking water for livestock.

This is a curious one. And an extremely disappointing one from my perspective.No impact on a 100litre water-butt collecting rainwater from a garden room. So, I bought two. Twice as good, right? Twice as ineffective. Looking at the reviews, quite why this works for some and not others is a bit of mystery, but maddeningly frustrating when it doesn't. Quite literally about to decommission my water-butt, as the water feels unusable and continues to smell absolutely disgusting with scum on the surface, no matter how many times I empty, clean, refill.UPDATE: Obviously, persevered for a while and the particularly odious odour issue has definitely significantly. I'm tempted to change the star rating to **** BUT ... I did also subsequently combine with a Hoselock chemical product. I will update again when this product runs out and we'll see what we're metaphorically left with.I would also add, as someone elsewhere responded in a question, the quality of the water entering the butt from the drainage site may also have a further bearing. [e.g. Someone suggested filtering the water with, say, some mesh/old tights in order to stop extra material going into the butt and potentially contaminating the water, too. Obviously, this would necessitate occasional cleaning of the filter.
