Very good value
What really sets this product apart from other water conditioners is its level of concentration. I regularly change my tank water using three standard size three gallon buckets. This means I only need to use approximately one ml of conditioner to treat all nine gallons. This is exceptional value for money compared to other products that has required me to use a whole cap full of conditioner to treat the same volume of water. Using the product at this rate means it’s going to last me a very long time. The added bonus of the cap having a 1mL indent really helps me measure out the correct volume of conditioner each time.

Great for my houseplants
This is great to soften and remove chemicals from tap water before I water my houseplants, they all look so much happier and no brown tips.

Amazing stuff
This is such phenomenal value that it's untrue! I pay £6-£7 for a 120ml bottle. This works out so much cheaper, and the bottle is so big that I imagine that it will last me a year or so. The top cap isn't clearly marked with small dosages though, so it's hard to use it for small water top ups, but that's a small gripe and it's not the end of the world. This bottle treats over 35,000 litres, it instantly removes chlorine, neutralise chloramines and detoxifies heavy metals in tap water, which can kill the fish in high enough doses. The only bad thing I can say for this is that it does create ammonia, as it converts the chlorine to ammonia and that's how it makes it safe, but that's a small trade off for safe fish and water changes. I really couldn't recommend this stuff enough, I have been using it for years now, I don't even remember a time when I didn't use it. It's very cheap on here, lasts forever and it does the job perfectly. Excellent product. Tip: Use the cap off the smaller 120ml bottles to put on this big one. It will allow you to drip it in rather than using the very inaccurate measurement top that comes with it, as the mesurements don't go down low enough for even my 400l tank. The old lids let you count drops which is much easier. If you don't have one, get yourself one! It will make your life much easier. I think even the tiny sample bottles use the same size dripper cap which you can get at pets at home for a few pounds.

Excellent Value
Seems effective. Fish still alive! Excellent value. I would like to see a smaller spout to make measuring small doses easier.

Great product, would like a narrower nozzle for dosing.
I got this because it seems to have higher concentration than any other brand I've seen - that means less solution per liter, less shipping and less plastic waste from bottles (and of course cheaper), but for me that is also its downside - the cap has a measuring cap for 1ml, 5ml and 10ml amounts, but 1 ml is meant to be good for 76 liters and for my tiny tank I really only need a few drops per water change. The opening of the bottle is too large for that and I guess I'll get a syringe for it.

For use in tap water to water indoor plants
We bought this to use on tap water that we water indoor plants with. This was a recommendation by a 'you tube' plant expert who advised this will help keep plants healthy by neutralising any additives. Only a small drop is required so one bottle will last a long time.

Superb products.
Superb product. API is one of my resources for many of my aquarium essentials. Never had any problem with any of there items. Great value for money, with many products giving you size options for what you need. All products from medicated to water parameters and plant care. These products are made with an ease of understanding for what that purpose is and will help you on your fish keeping journey.
