Its location can play a big role as intense
                     sunlight exposure and nearby trees can create algae and muck. Its depth and total water volume are also contributors as deeper ponds with more water stay
                     clear longer. Lastly, bioload and filtration are important things to consider for a low-maintenance pond.  Pond Fighter provides pond maintenance services all over Baltimore. For this job in Towson, the homeowner called us because of his tinted pond water. This
                    is caused by the pine needles that accumulate and decompose inside the pond. A remedy for this problem could be to install a pond net to prevent leaves from falling in. 
                    Pond cleaning service for fish pond in Owings Mills. Smaller
                    ponds are more difficult to maintain as smaller bodies of water are more susceptible to develop algae and muck.
                    A pond like this requires constant skimming of debris and water changes for it to stay clean. 
                A fountain provides water circulation that can decrease overall pond maintenance. Dissolved oxygen released by the fountain also help clear the water. For this backyard pond cleaning service we had to use a wheelbarrel to removed thousands of
                    lbs of vegetation and overgrowth. After this pond cleaning service the pond is now ready to be stocked with goldfish, koi, turtles, and other
                    aquatic critters. For a pond this size we recommend a Aquasurge 5000 pump with Biofalls 6000 for filtration. Since this pond was over 4 feet deep it will stay muck free longer as the
                    sunlight cannot penetrate deep enough for algae to blossom. The pond water is heavily tinted due to the pine needles. For ponds built
                    under trees and vegetation we recommend you install a net to protect it from leaves and other debris and decrease your overall maintenance. The big koi fish were reintroduced to the dechlorinated non-tinted water. Koi this size
                    are clearly visible to birds of prey so they will need a hiding place inside the pond. This pond was built with a fish tunnel in the middle that allowed them to get shade and feel safe. Small backyard fish pond with dry stack stones and waterfall. Smaller ponds
                    require more maintenance because there is less water. We recommend you get a fish net and scoop out all the leaves that acumulate inside the pond such as in this picture. Servicing a pond this size takes about 5 hours. When we are done the water is crystal clear. Bare bottom ponds allow for easy removal of muck and debris.
                    However, your liner will be exposed to damage as there are no rocks covering it. 45 mil epdm liner with underlayment should be safe without rocks but if a heron sticks its beak than you are screwed.

We added new gravel and installed a TetraPond UVC-9 GreenFree UV Clarifier. When green algae is exposed to the ultraviolet light
                    the reproductive abilities of the algae are destroyed. Also known as cyanobacteria, green algae is a very common problem found in ponds. They thrive in shallow, warm, water with lots of nutrients and sunlight.
                    Too many water lilies, irises, and cattails inside a goldfish pond. The plants were added
                    because the pond was not built deep enough which caused a lot of algae and muck. However since the plants were not inside pots they quickly grew and took over the pond.
                    If you decide to add plants we recommend you place them inside pots and put them along the edge of the pond (the shallowest areas). Removing all the vegetation from your garden pond allows you to see the fish. This job required us to pull

    Koi pond cleaning Bethesda, MD

    Posted: 9/7/2020

    Check out this nice looking koi pond equipped with a Pondmaster 40W UV clarifier. These lights are designed to be used with the pump to kill algae and clear the water. A shallow pond like this is more susceptible to algae because more sunlight penetrates into shallow water giving them access to nutrients and energy needed to thrive. After the cleaning service a net was added to prevent leaves from falling inside the pond. Left alone, leaves will rot and release excess nutrients that will discolor the water and disrupt the balance of the ecosystem.

    Pond Maintenance Glen Burnie

    When cleaning a koi pond we first check to make sure your water paramaters aren't drastically different. We test for things such as ph, water temperature, and chlorine to ensure fish safety. Based on these results we can determine whether to do a 100% water change or not. In this video, June is cleaning the bottom filters inside the pond. This allows us to drain all the muck out with the remaining pond water. Clean filters will increase water flow which will increase overall filtration.

    Small Backyard pond with waterfall construction

    using aquascape premium products to construct a backyard pond.

    After excavation we are ready to add underlayment, liner and rocks. For this pond we used an Aquascape skimmer, Aquasurge 5000 pump and Biofalls 1000. An Aquascape skimmer houses and protects the pump from debris. Without it the pump will be laying at the bottom of the pond making it more prone to clogging and damage as there is nothing preventing muck from entering the intake. A skimmer also gives you easy access to the pump as it is installed along the egde of the pond. The Biofalls 1000 plays the role of both waterfall and filter. The sponges and bioballs inside provide mechanical and biological filtration while the waterfall create circulation and aeration for your fish.

    Our client wanted his neighbor's koi so we got out our jumbo fish net and waders and went to work. Catching koi without draining the pond is a major headache but at the end we were able to safely transport 5 healthy 16 inch butterfly koi to our client's backyard pond.

    Using a wheel barrel and trailer to clean huge backyard water feature in Woodbine

    When a pond is left to sit for over a decade plants you initially put in for decoration and filtration quickly outgrow their pots and take over the pond. Soil and nutrients from rain runoff is the cherry on top and your pond has successfully transformed into a wetland marsh. You can kiss your fish goodbye as they will never be visible again. The only way to prevent this is to have your pond maintained on a yearly or bi-yearly basis.

    Tub pond renovation

    Small tub pond in owings mills with dead bird inside

    Thanks to the landscaper who decided to trim a tree into this tub pond we were able to come and rescue it. We even found a dead decomposing song bird inside that smelled terrible. In this video we added Pennsylvania mountain stone along the edge of the pond which made it look more natural by hiding the plastic tub. When renovating a pond we can add rocks, increase the pond size, build a waterfall, add a skimmer, add lighting, etc.

    Over time the ground supporting your pond can lose its strength and crumble. This occurs when their is nothing supporting the walls. We recommend a pond renovation where we dry stack rocks alongside the walls to give it proper support. It is also very pleasing aesthetically.

    Pond plants

    water lilies inside your pond can provied shade and cover

    Water lilies provide cover from the sunlight which reduces algae growth and water discoloration. If your pond is exposed to the sun we recommend you add plants that provide shade. Water hyacinths and lilies are our go to plants. When servicing a pond we can save your aquatic plants and replant them at the end of the job.

    Pond Cleaning Baltimore

    Pond built under heavy vegetation

    A small pond is limited in the number of fish it can house but can have the same soothing effect as larger water features. This pond was built near a lot of vegetation which was removed and hauled away from the property.

    Mechanical filtration

    cleaning filter mats do not kill beneficial bacteria

    Filter mats clean your water by physically trapping waste particles and debris. They are also the breeding ground for beneficial bacteria which convert harmful ammonia (released from fish waste and organic matter) into nitrates.

    Testing water before cleaning a koi pond

    Drastic changes in water paramaters can be harmful to your koi. We take preventative measures to ensure your koi experience the least amount of stress while servicing your pond.

    In addition to cleaning ponds we also do pump replacements, submersible lights, and repairs/renovation. In this video June is installing a new Aquascape AquaSurge 3000 GPH Pump in Columbia, MD. The pump wire is buried underground and inserted into your outdoor-rated GFCI outlet.

    Removing 500 lbs of water lilies in Bowie, MD

    Excessive aquatic plants are a common problem among ponds. Lilies, irises and cattails are known to take over ponds as they multiply very rapidly. Although plants provide filtration and oxygen for the fish, too many can hurt the aesthetics and the ecosystem of the pond. In this video, we had too remove the lilies because they took up too much real estate and clogged up the pond. Overall water volume is very important in keeping your pond clean so removing these plants made room for more water.

    Relocating Koi into aerated holding tanks

    We are masters at handling koi and guarantee their health for the entirety of the job. In the following video June safely catches the fish with a large net and relocates them to an aerated holding tank near by. We slowly acclimate the koi during the cleaning to reduce their stress when reintroduced back into the pond.
