Spring is not too far away for our Northern hemisphere friends

Many ponds meet serious problems when weather starts to warm up as it does in Spring. The problems encountered are often bacterial disease problems such as ulcers (this is probably most common) identified by sores appearing on sides of your fish which even develop into holes. Treatment is difficult and expensive and often leads to other problems because antibiotics are involved.

There is only 1 product I am aware of that prevents this type of disease. It is called Lymnozyme in USA and Genesyz in UK.

It does not cure diseases caused by aeromonas and pseudomonas bacteria (those responsible for many problems) but reduces their population to very
very low and non-dangerous levels using a well known biological process called "Competitive Exclusion".

If you want to know more take a look at ww.genesyz.com or go and explore Dr Johnson's web site www.koivet.com and follow any links to lymnozyme.

By the way this is one of most important water gardening sites you will find anywhere.

Other problems to look forward to are green ponds - one simple reason if you have an UV - your lamp needs changing. These UV lamps do not last more than
8,000 hours (less than 1 year). They may still shine but they are not emitting UV in sufficient concentration to be effective.

Often with the increased feeding rate that will start to happen in Spring your filter may not be able to handle a sudden and large increase in ammonia. Do things
gradually is the simple message.

I hope you have been feeding your fish during winter unless they were totally motionless in water below 8 degrees.
