AquaSafe Water Conditioner - 16.9 oz.

• Instantly makes water safe for aquarium use. Neutralizes chlorine, chloramines

Perfect for beginner and beyond:
Whenever you add new tap water to your aquarium the chemistry of the water changes, these changes can be very harmful to the fish depending on how drastic they are. So it's recommended you do a 10-20% water change every week to your aquarium to help reduce chemicals like ammonia and dilute the nitrites etc. But the tap water also carries harmful chlorine and chloramine. Tetra AquaSafe removes both and enhances the stress coat produced by your fish, thus making it perfect to condition your aquarium. I've had no problems whatsoever with it, and it has greatly improved the overall health of my fish. I personally don't use it with every water change (although its recommended that you do) but that's usually based on the amt being added and the condition of my tap water. Use 5ml to treat 10gal

If you have chloramines in your tap water, this is the water conditioner to get:
This Tetra Aqua product is easy and effective for making tap water safe for aquarium fish. I like that the bottle has a squeeze top and a cap, has a narrow profile, and adds both slime coat additive and dechlorinator/heavy metal neutralizer. The product also eliminates chloramines. Since chlorine and chloramine are both broken down with one tool, it's a superior product over the NovAqua Water Conditioner (but only if you have chloramines to deal with - you need to check with your local water provider). With NovAqua you have the benefit of a product that adds beneficial water electrolytes, but nothing to cover chloramines, unless you also purchase the sister-product of Amquel. Remember, you want to add as few additives to your aquarium as you can safely manage, to decrease the overall ion load on your fishes' gills. The narrow profile of the bottle means I can easily store the bottle among my fish stuff. It slides in really easily on my shelf of fish paraphenalia. It's a nice break from all those round bottles that leave a lot of space unused. It's also more ergonomic, squeeze-wise. With the squeeze top, I can choose to add actual drops for small tanks or use the cap as a cup measure for larger tanks. This takes care of a problem many conditioners have that are either established for tiny tanks (ie - under five gallons...where you should only add a drop per gallon), and for larger tanks, where you need a teaspoon for every 10 gallons. So this one product can service those one gallon betta tanks from the squeeze top and those 50 gallon tanks from the cap. There are also equal measure marks on the side of the container for making up really big batches of dechlorinated water. Each raised measure equals 10ml, or 20 gallons. Anyway, I like that this container makes my life easier. It would be an even better product if the inside of the cap was marked for each teaspoon amount (one gallon amount). As it is, I only needed to measure out a teaspoon the first time, poured that into the cap, and then marked that amount with a sharpie for future use. In summary, if you have chloramines in your tap water, this is the product to get for conditioning your aquarium water. If you do not have chloramines, then I suggest the NovAqua Water Conditioner (to add electrolytes) instead.

Cheap handy product:
I got this at Wal-Mart and its OK, but not as good as the one you get from a fish market that are more used by professionals. The concert is the same however, the quality makes the difference. If you just want some hobby little fish tank, you may be able to get away with it. I would not use this product on regular basis, but for quick grab item in case of run out of my regular product, its good and Cheap.
