it is common knowledge to use a dechlorinator to prepare new water for an aquarium. what ive found that isnt common knowledge is that if your dechlor isnt also a detoxifier, your settling for less. below are a few reviews of my favorite water conditioners. the cost effectiveness of these two alone should make for a smart buy.
Prime by Seachem
directions for use:
1 capful (5 mL) for each 200 L (50 gallons*) of new water. For smaller doses, please note each cap thread is approx. 1 mL). This dose removes approximately 0.6 mg/L ammonia, 3 mg/L chloramine, or 4 mg/L chlorine. May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. Sulfur odor is normal. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite in an emergency, up to 5 times normal dose may be used. If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose. one 8.5 fluid ounce bottle treats 2500 gallons.
this stuff just plain rocks. seachem packs so much goodness into such a small bottle. ive been using this stuff for about a year now and it has served me well. one 8.5 fluid ounce bottle has single handedly taken care of 6 tanks (120 gallons total) worth of water changes for almost a year now. i wont get into the math. its been very useful for parameter fluctuations due to power outtages and equipment malfunctions (ammonia and nitrite). when im treating a sick fish in an uncycled environment, it adds to my peace of mind that there isnt any ammonia building up. its especially invaluable when trying to cycle a tank with fish in it. the only thing is, i cant seem to find any literature pertaining to exactly how much nitrite and nitrate each dose will detoxify.
directions for use:
1 teaspoon (5 ml) for each 10 gallons. This dose will remove chlorine, 1.2 ppm of ammonia, 2 ppm of nitrite, 13 ppm of nitrate. One 16-ounce bottle treats 960 gallons. Water treated with Amquel Plus cannot be accurately tested using Nessler's type ammonia tests or Winkler type D.O. kits.
pretty much everything that i said about prime, you can apply to amquel plus. dont mistake amquel plus for kordons amquel. they are not the same product. i tried out some amquel plus that was given to me by my lfs owner on my 10 gallon betta tank (now tropical) for a month or two and i saw no difference whatsoever (between amquel and prime). an extra plus for amquel plus (pun not intended) is that it actually states how much nitrite/nitrate each dose detoxifies. the drawback is stated in the directions for use. although that depends on your testing eqipment.
thanks for sitting through this looooong review. i just think that its important and helpful for aquarists to know what is available to them.
