Question:
It's my experience that dechlorinator actually contributes to apotential algae bloom. When the dechlorinator releases the bind betweenthe chlorine and ammonia, the ammonia can then be converted to a goodfertilizer for your algae. There is a very simple way to avoid usingdechlorinator using a filter on your hose like those you use under yoursink to remove chlorine and ammonia. The under sink jobe have 1/4"fittings, but you can get a "whole house" version with 3/4 inchfittings. I have more details on my web page in the Tips section.Don't forget... Don't add anything to your pond that you can't take outand you won't have to do any water changes.

Answer: I tend to disagree, water changes are a "good" thing to do, but thatis just my opinion.

Water evaporates. You top off your pond. Repeat throughout thesummer. Hmmm. What happens to all the dissolved solids? Theydo not evaporate. They accumulate.

I have never had a problem adding tap water directly to eitheran aquarium or my pond. Up to a 50% change! Now, this ischlorinated water, not chloramines.

If you're really paranoid, go to your local Home Depot (orequilivent). Buy a RV water filter (activated charcoal canisterfilter). It has a hose in one end and a threaded coupler fora hose in the other. Connect your garden hose to the cannister,turn on the water (low volume). Presto.

This works fine on ponds around 3000 gallons or less.
