UV bulbs To ensure that your UV units are working to their maximum it is now generally recognised that you change your UV bulbs every six months. While you have the bulbs out of the unit, you will also need to remove the quartz sleeve very carefully as they are very brittle and will crack with the slightest knock. Once the quartz is out they generally
need cleaning off as they do tend to get a build up of limescale on them depending on how hard the water is in your area. I have at times had to use some very strong descaler to remove limescale. You should bear in mind that if your water
does start to turn green, it may not be due to the bulb not working, but rather the ultra violet not being able to pass through the quartz to the water.
Water purifiers There are various makes of water purifier available to the koi hobby, but it is not simply a case of buy one, fit it and forget about it. Each of them has a lifespan of so many thousand gallons of water passing through them, and each of them is different. If you are the sort of person who
can record the amount of water you are changing or you have a meter fitted to your purifier then you can easily change the cartridges at the right time. However if you are not, then it is probably a good idea to change them once per year to ensure they do not become saturated with chemicals and metals etc, as these can leach back out if not maintained.
Strainer baskets If you have skimmers fitted to your pond or pre-pump strainer baskets, you will have to periodically remove the baskets and empty any debris that you may find in them. If you have trees near the location of your
pond you will, without doubt, have leaves falling into the pond that will end up in the skimmer. If these baskets are not emptied there is a possibility that the pump could be
starved of water and this will be detrimental to your pumps.
Filters What maintenance you need to carry out on the filter system will depend on the type you have chosen and also the length of time that it will take to carry out. A multi bay system with maybe a vortex,
brushes, flocor and Japanese matting does need to have the brushes cleaned out regularly. This is a job that can take some time depending on the number of brushes and it is quite messy. The areas beneath the flocor and
matting need draining at least weekly to remove any fish waste, and the same also applies to the vortex. A bubble bead system that is fitted with a
vortex or sieve will need to have the vortex purged or the sieve cleaned out weekly. The bubble bead itself will need back washing and purging to remove the waste. A Nexus system will need to have the
centre chamber agitated to remove the trapped waste from the Eazy area and then be purged to waste on a weekly basis. Sometimes it can be more often during summer months when heavy feeding is in process. But with only five minutes cleaning time it is no hardship
