10 Steps to Clear Water
10 STEPS TO CLEAR WATER
#1. Stop feeding your fish till the water clears! Or, at the minimum, reduce feedings to 1-2 times a week (scoop out anything not eaten in 10-15 minutes). There should be plenty of natural food in the average pond for your fish to feed on.
#2. Thin out your fish if you have more than one goldfish for every 50 gallons of water or one Koi for every 150-200 gallons on average. (If you just can’t part with your fish, upgrade your filter to handle the extra fish- see step 5)
#3. Clean out any leaves, mulch, and any other debris that has collected in the pond. As they (leaves, etc.) decompose they provide a constant flow of nutrients which feeds the algae! Net leaves before they sink to the bottom.
#4. Make sure your pump is located on the opposite side of your pond as far away as possible from the waterfall stream it feeds. This ensures complete circulation throughout the pond thereby preventing stagnant areas.
#5. Add the proper quantity of aquatic plants especially submerged plants and floating plants for your size pond (see page 28 in our online catalog (or ask for a copy) under the heading “What Combination Works Best” for recommended quantity). Place floating plants in a stream, near a pump, etc. where water is continuously pulled past their roots.
#6. Add or upgrade your filter system to a 2-step system consisting of: Step 1- have a pre- filter where the pump is located and Step 2- have a proper size biological filter (KISS TM Filter). The biological filter is best installed out of the pond and is often hidden as a waterfall.
#7. Seed your pond weekly with beneficial bacteria such as Hydro-Bugs or Green-be-Gone. Dry formulas are more economical than liquids in general. Phosphate (Phos-out) control products can also be very helpfull.
#8. Add a single layer of fist-sized round stone across the bottom and on any shelves in the pond. This prevents fish from stirring up any dirt that collects on the bottom of the pond.
#9. Make sure your pond is not receiving run-off from the lawn, or any surrounding ground. Raise edges a few inches with stone and foam if necessary so run-off goes around the pond instead of into the pond.
#10. Do a 10-20% water change every two weeks. Be sure to purge the water from the bottom of the pond and add a dechlorinator if you use city water to refill it.
IF all else Fails…
Science to the rescue! Just add a UV Sterilizer! A proper size UV sterilizer with a proper size pump will give you clear water within 1-2 weeks nearly 100% of the time!
What not to do!
Don’t keep draining and refilling your pond every time it begins to run green. You’ll just repeat the cycle again and again…!
Don’t add blue or black dye if you wish to grow submerged plants and see your fish.
Don’t apply any type of algaecide or water clarifier without checking with us first.
In any case….always keep in mind green water is a people problem... not a fish or plant problem!
Your fish and plants will be perfectly happy (even prefer!) green water over clear water. We just want to see our fish!
