Depending upon the condition of your pond, you will either need a light clean out, or a major
clean out. Regardless of what category you fall under, the 2 necessary products you’ll need now and year round are a Beneficial Bacteria – and a Dechlorinator.

Use Microbelift’s Super Start – if you’re just starting up your filter, otherwise, use the bacteria of your choice. The Super Start seeds and colonizes the filter to jump start the biological filtration process. Dechlorinator’s are necessary for any water changes or when adding water to your pond. If
you have an Auto Fill Valve you don’t have to worry about adding a Dechlorinator since the amount of incoming water is minimal. But always use it when doing
significant water changes. You can also use a Hose End Filter to top off your pond that can be plumbed inline or attached to a garden hose. It’s good for about a year or up to 10,000 gallons.


If your pond is relatively clean, that is,
there is minimal gunk on the sides and bottom, just scoop out any
debris with a good Skimming Net or vacuum out debris with a Pond Vacuum. The Muck Vac is
a good low tech vacuum for small ponds that attaches to your garden hose. Scrub rocks with a bristle brush if needed. Do a 25-30% water
change and add a Dechlorinator and Beneficial Bacteria. Add
Pond Salt and/or Koizyme to
help keep fish healthy. Clean up your pond plants by cutting back dead debris. If plants are overgrown, divide and repot them (AquaticSoil, Plant Baskets, Aquatic Fertilizer). Skip
to ” Check Your Equipment” under Maximal Clean out. That’s it! Done! Just be sure to keep using your beneficial bacteria regularly in
order to keep accumulated gunk in check.


If you suspect any damage to your pond equipment, skip down to “check your equipment” before draining your
pond, otherwise, continue with your cleanout. Drain pond until it is almost empty and fish are easy to catch. Use a Skimming/Fish Net or Koi Sock to catch them with. Place the fish in a kiddie pool or holding tank with the water drained from the pond. Use the excess water for your garden or lawn, it has a lot of nutrients in it that act like a fertilizer. Be sure to put a Pump or Air Pump in the holding tank so your fish receive a steady supply of oxygen. Cover your tank with a Pond Netting/Cover to protect fish from jumping out.

Clean up your pond plants by cutting back any dead debris. If plants are overgrown, divide and repot them (Aquatic Soil, Plant Baskets,Aquatic Fertilizer).

Scoop out the sludge on the bottom with a good Skimming/fish net, or even better, vacuum out excess debris with a Pond Vacuum. The Pond OVac 4 is the best in class and reasonably priced. Scrub rocks with a
bristle brush, and rinse or power wash remaining debris. Vacuum or pump out remaining water.

Refill your pond, leaving room for the holding tank water. Add a
Dechlorinator – like Aqua Extreme or Aquasafe, and a Beneficial Bacteria like
Microbelift PL. Follow manufactures’ recommended dosage depending on water volume.

To calculate water volume: measure the length, width, and depth of
your pond. Then, times the length times the width, times the depth
times 7.5. In other words, L X W X D X 7.5 = your gallons of water.
Let the pond circulate for a few hours, and then check the Ph of the
new pond water with a Test Kit, and
compare it to the Ph in the holding tank water. If they’re in close
proximity, put most of the holding tank water back in pond, catch the
fish like you did in step 1, and place back into the pond.


This is the best time to clean and/or replace any filter media, or foam pads. The reason being that your beneficial bacteria most likely did not survive the winter, so your pond is starting from square one.

Rinse off your media well, but if it is too gunked up or deteriorating, replace it (Replacement Parts)
Check your UV BULB if you have one. You should replace your bulb once
a year even if it is still ‘on’ because it loses it’s effectiveness
past the 1 year mark. Check the sleeve for any cracks and replace it
if necessary (Replacement Parts).
Otherwise, clean it well with some distilled white vinegar. A bulb
will not work if the sleeve is dirty. For submersible pumps,
clean the pre filter and the pump intake. If there is excess debris
on the entire pump use Pumpguard to get it clean. If you stored your pump over the winter, test it
first in shallow water to make sure it is running properly. For
external pumps, clean the strainer basket and check for any cracks.
Many pumps have easy access to the impeller. Clean it. Small stones
or accumulated debris can severely damage your pump. Use a Pump Bag to protect your pump if necessary. Consider purchasing an extra impeller (Replacement Parts) or a
back-up pump. Check the Ph of your pond with a Test Kit to make sure it is around 7.5. Do this periodically throughout the year as well.
