When creating an outdoor fish pond you need the right environment, fish and maintenance to keep your water feature looking its best.

Check water chemistry and filtration. Sunny may have developed a bacterial or fungal infection due to the switch in environment. Clean water is crucial to resolving infection. Perform regular partial water changes. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. Maintain water temperature between 75 F and 72 F. Minor infection maybe resolved using plain aquarium salt (NOT table salt). Salt is a great general tonic. It reduces stress, improves gill function and aids in recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup of tank water and gently pour it into the tank. Treat until symptoms resolve. When performing water changes, use just enough salt to treat the water being replaced, not the entire tank volume. If necessary, you can use a broad spectrum medication if symptoms persist. Look in the aquarium section of the local pet or fish store for products such as Kanaplex, Maracyn or Lifeguard by Tetra. Follow label

I'm sorry you are having difficulties with your aquarium. There are several issues that should be dealt with right now. They are water chemistry, aquarium size and choice/number of fish. Any new aquarium should be set up and, ideally, run empty for several weeks (usually 4-6 weeks). This is so beneficial bacteria have an opportunity to populate the substrate and filter. These bacteria are necessary to break down wastes that fish will produce. The technical phrase for this is "establishing the Nitrogen cycle". These bacteria will break down wastes into ammonia then nitrites then nitrates. Nitrates can then dissipate or be absorbed/used by live plants. In high enough concentrations, ammonia and nitrites are toxic and can kill fish. Cycling a tank with fish is possible but it increases the risk of loss. Water chemistry should be checked every few days using a liquid home test kit. A water sample can be submitted for testing , but is not as convenient as testing yourself. Most pet sto

Hi and thanks for your request. To better control Nitrite and ammonia spikes it is best to cycle it for a month at least and measure nitrites, ammonia and nitrate constantly. Please follow the recommendations here below: The nitrogen cycle is the process of various bacteria converting harmful waste. It involves 4 steps: The first step is the decay of waste products of fish, plants, and invertebrates, along with any dead organisms or uneaten food. As these materials decay, ammonia is produced, which at even low levels will burn the gills of fish and choke off their oxygen supply. Bacteria called Nitrosomonas consume this ammonia and, in the process creating another chemical byproduct called nitrite. Although nitrite is toxic (preventing blood from carrying oxygen), fish can withstand roughly twice the amount of nitrite in their water when compared to ammonia. Next, other bacteria called Nitrobacter consume the nitrite and, in turn, release a less toxic chemical called nitrate. Nitrate

The majority of the acclimation guide is intended for introducing animals recently purchased online into a quarantine environment that have been inside a dark box for 24+ hours and the water quality is most likely degraded from waste. Hopefully you followed these steps before introducing your pond animals into their quarantine environment. After the quarantine period the acclimation from this environment should be relatively easy and quick – given the water parameters in the quarantine environment are ideal and similar to your pond. The best way to move the fish would be to put them in a 5 gal. bucket and float the bucket in the pond for at least 30 minutes so the temperature in the bucket can gradually reach the same temperature as the pond. Make sure you do this in a shady spot of the pond or during a time period when the bucket will not be in the sun. In order to keep the bucket from tipping it may take some creativity but it may be as simple as using a wooden pole laid across the

You shouldn't need anti ich medication for your sliders. The water conditioner (anti chlorine) is always a good idea if you use water from a municipal source. My personal preference for water conditioners are AmQuel Plus, NovAqua and StressCoat. You can purchase them online or in the local pet store. Be sure the water is no deeper than twice the length of the shell. You can read more about slider care here: http://www.anapsid.org/reslider.html
