Hi, I'm Gregg your local Koi Doctor.

Keeping koi for over 10 years, marines for 5 and treating koi aliments from the very start, I have a vast knowledge of the hobby and by experience have developed in-depth knowledge of koi diagnosis, medical, chemical and surgical treatments; as well as pond construction, maintenance and pond optimisation.
Learning from the very best (Duncan Griffiths author of Step by Step Advanced Koi Diagnosis & Treatments) and featuring in the book itself from a young age performing koi treatments, I learnt the basics spurring me on to delve deeper into the science of koi, koi health and chemical treatments. Understanding what to do when a koi is ill is one thing, but having the ability to analyse why it needs a treatment, what it will do and what to do over the course of treatment is key to understanding koi health and being able to almost revive even the worst cases of sick fish.
My skills do not stop at Koi, as although they are generally the most vunerable to diseases and improper care, any ornamental fish can be analysed and treated; as well as filter checks and general pond maintenance to get the best out of your fish.
I also offer quotes for koi collections and pond clearances.
​Highly recommended go-to guide for all Koi health diagnosis and treatment needs.

Featuring personal treatments from a young age.

Koi Health Treatments

Sometimes fish require a variety of treatments, and I have learnt to cater to all needs, be it surgical stitching, bone manipulation, medical injections or simple topical treatments.
Water Testing

The basis of most problems, if not bacterial, viral or medical, are mostly in the water and can be easily rectified with the know-how.
​
When demands for high quality and accurate results rise with the purchase of more and more valuable pets and investments, I use professional Hanna testing to ensure precise results and recommendations.
Water Treatments

When a fish's mucus has been analysed under a microscope and bacterial issues have been identified, a broadcast water treatment can be used to eradicate most problems.
Diagnosis

With Koi health, some problems are unseen to the naked eye and can go undetected for months before sudden fatalities.

For this reason I use high-end microscopic analysis to determine what is actually going on, on fish and can then accurately prescribe the best treatment for either a specific, or variety of issues.

Other times, problems can be entirely unseen to most or visible but undetectable by microscope, and this is where experience is invaluable for determining possible viral infections that could cause mass fatalities if left untreated.
Pond Maintenance

Sometimes the main problem with a pond can be poor turnover or lack of sufficeint filtration causing high parameters and bad water (the most common reason for ill fish). I can provide advice on optimised filtration and faulty pumps or filtration and fix issues on the spot.
