Does a fair amount of help , but I'm overly cautious too. They SAY SAFE, still they should PAY for those fish killed! Copy a Sample of water and the fish, send to them. If they say harmless they should STAND BY THEIR WORD! How heartbreaking to find your care and love worthless!I've used this product with NO ADVERSE EFFECT on my fish, you must NOT be over zealous but USE TIME! Avoid over doses, Remove some water now n then too, avoid build up. Wait LONGER between doses, or use charcoal fillers to weaken. Just some IMO.
