The best water conditioner out there

Seachem prime is my absolute favourite water conditioner. It requires only two drops per gallon so it is cheaper to use than any other I've tried. Not only does it dechlorinate water, but it also binds ammonia and renders it harmless. Perfect to use to protect your fish if your tank is uncycled. The only problem is that it does smell like sulfur so do keep the lid twisted on very tight and DO NOT spill it.
