Swell UK Adolygiadau

So easy to use and appears to be accurate. Chlorine can be lethal to Koi so something like this is ideal. Good price too.

Work perfectly well with the chlorine checker.

It's not cheap but it is the best,much less waste,clear water,and good growth.

As advertised, decent quality

Started clearing a. Few days later so far looking good 👍

It does the job as far as I know, but a little fiddly as the holder to use the test tubes is rather weak. ( I used to work in a laboratory! ) The delivery was good and quick

Lovely tank and lovely delivery driver the tank is very big and very lovely my fish love it thank you

Amazing product. Best test kit, very accurate and easy to use. 100% recommend.

Seems to work but not happy as only half my order turned up.

Seems to work, but only half my order turned up.

Never arrived, only got half my order. swell don't answer their phones anymore, submitted a contract form but they never replied. Had to get my money back from my payment card. Terrible company. ...
