This is a good explanation and drawing of how to build a constant flow regulator for doing constant water changes on your pond. 

Many folks have struck on the idea of using a slow trickle of fresh water into their ponds paired with a standpipe-type overflow to help rid the pond water of nitrates.  The simplest and cheapest way to accomplish this (presuming there is a suitable overflow) is to use off-the-shelf drip irrigation components to regulate the inflow of water.  However, knowing that these components are less than precise and prone to drift (varying the flow rate) and other forms of failure, I decided I could design a low-flow device that would be pressure compensated, could be precisely set and likely more reliable than store bought drip irrigation parts.  (In a former life, I was a mechanical engineer with a background in hydraulics.)

1 Introduction

The addition of Montmorillonite clays to Koi ponds have proven benefits. Many Koi keepers use these clays with great success. Montmorillonite clays are commercially available under various brand names depending on the country of origin and who is branding it. They vary in chemical composition and purity, enhance water quality, replenish and augment minerals and remove certain unwanted wastes.

Have you ever thought about the almost insurmountable problems in making a pond waterproof? Is a completely waterproof pond an impossible dream? Substantial leaks need attention, no doubt about it. However, at some point or the other, insanity will overcome you, before each and every leak is found and fixed in the average pond.

Bacterial Infections - Choices OTHER than Antibiotics

“The World is unprepared for the coming plagues” says Laurie Garrett in her recently published book - The Coming Plague - which documents the fight-back microbes are making on the planet. After four decades of assuming that the conquest of infectious diseases was imminent, people on all continents now find themselves besieged. Doctors and scientists have been fighting a fifty year battle with infectious microbes. In recent years strains of TB, cholera, malaria that are resistant to all known anti-biotics and drugs have sprung up all over the world. New bugs and viruses that kill in hours have been recorded in recent years.
