In the spring when the snow has melted and the ice has receded off the pond. Still keep the De-Icer and Aerator in the pond as sometimes temperatures do fall at night. This is the time that the Ecosystem is emerging out of dormancy and critical that we take measures to prevent a disaster from occurring, with this, I mean excess algae growth, imbalance in water quality parameters and fish disease. First off, as the water temps rise, the fish become a bit more active and since it’s too early still for a full cleaning, whether you are planning a cleaning or not, we have to address several preventative measures. The pond water is now between 45- 50 degrees. Let’s get the system running to get the aeration, and filtration needed. The filter pads, pumps, uv units, tubing etc. were thoroughly flushed cleaned in the fall by us so that all you have to do is plug it in. or if you do it, fine. Clean as best you can and start up the system. Perform a water change. See article on water changes, and add the Dechlorinator/Ammonia remover to the pond. We need to add cold water enzymes at this point to breakdown the organic load that may have accumulated over the winter. Use your skimmer net to remove as much as possible, stirring up the water may cause the water to “murk” up but the filtration will remove that in a day or so Use Accuclear to speed up the clarity. The remaining load that’s in the tough to reach spots can be worked on by the Cold water Bacteria, Microbe-Lift Spring Summer formula or Clear Pond Fall Winter Formula. Both are Cold Water Bacteria that eats away at the remaining sludge accumulation. Now let’s address the Algae. I favor the GreenClean… Great stuff. Use this if string algae are growing excessively. If you catch it midstream you can use this or we use Algae
Fix & Barley to control it from there. As the ecosystem comes into swing, here comes the green water algae blooms. If the water is not gin clear, get your UV sterilizer/Clarifier up and going. The Sterilizer will combat the Green Water Algae and kills Parasites that could be proliferating right now. If in the past the green water has not been a big deal but your pond from time to time gets murky or blooms occur, then use Accuclear to remove the suspended particles. I would opt to have a UV Sterilizer due to the fact that it kills parasites! NOTE! Make sure you turn off your UV Sterilizer/Clarifier for 3 days when adding Beneficial Bacteria! Once water temperatures remain stable in the 50-55 degree mark, you are now feeding your fish, adding nitrifying beneficial bacteria to the pond to seed the biofilter. Aeromonas and Pseudomonas are on the attack right now. They are pathenogenic bacteria, a “bad” bacterium that is afflicting disease on your fish. Don’t think your pond does not have them… They are in every pond! See our article on Aeromonas alert. Get KoiZyme to control the population and keep disease from affecting your fish.
Add Bacta-Pur Pro 100 a probiotic that prevents development of various other diseases in your pond. And boosts the fishes eco-immunity.
Start fertilizing the plants with Pondtabbs and adding as needed due to possible loss over the winter. The pond is now stabilizing out and the ecosystem is coming into balance. Read articles: What we use during our visits, The Cycle and How to Speed up the Cycle for our recommendations on products. A quick run down… For immediate seeding of the pond that eliminates the break-in period, get TurboStart or Bioseed Gold. Give an extra boost of Nitrifying bacteria such as KC Nitrifier. If you don’t mind waiting, just stick with the Microbe lift or Bacta-Pur system. Add Activated Carbon to the pond. Carbon offers a ga-zillion “hotel rooms” for the Nitrifiers to proliferate. Add Fritzguard to coat the bio-media for superb adherence of the Nitrifiers to the various surfaces in the bio-media as well as on the surfaces within the pond.
Keep a Test Kit available to check for Ammonia, Nitrites, Ph swings, as this is the time of year that they fluctuate drastically. Add as needed pH down, pH up, pH buffer, Ammo-lock 2, Dechlorinator/Ammonia Remover. Add or recharge your Zeolite to continue its role in absorption of trace Ammonia that can occur.
Your ecosystem is now balanced and ready for a beautiful season of enjoyment!
