can any one give me any advice, my tank which was set up nearly 2 weeks ago has the highest possible reading for ammonia, every thing else is fine but im now loosing fish because of it. i bought a chemical for reducing ammonia by putting a capful in every day but it hasnt helped at all & i did a half water change last night in the hope of getting rid of some but nothing is working! does it get in the tank just through the water coming through the taps? my local fish shop told me that. i have all new stones, ornaments, filter, heater etc so nothing should be contaminated. PLEASE HELP I CANT STAND WATCHING THE POOR GUYS!
