Caring for your pond
When autumn arrives, the first thing to do is carry out a partial water change. This helps remove excessive nutrients from the pond and prepares for the long off-season during the winter. Change approx. 30% of the water and top up with tap water. This ensures your fish benefit from good, stable water values; however, don’t forget to treat it with a water conditioner. AquaSafe makes tap water safe for fish by neutralising heavy metals from domestic pipes and reducing aggressive chlorine. What’s more, it provides pond water with sensitive colloids to protect fish’s mucous layer and so strengthen immune defences. Continue to add WaterBalance to your pond on a regular basis; it keeps water values stable until the next partial water change in spring. Now check the pH, carbonate hardness, nitrite and nitrate content and total water hardness using 6 in 1 test strips. Only by doing so can you be sure that water values haven’t been compromised. Clear water is not an indicator of water quality! Also have your phosphate content investigated at your pet shop. Phosphate is a nutrient for plants, but which encourages algae to grow if present in excessive amounts. Food remnants, leaves, overstocking and the presence of phosphate in spring water can all cause an algae attack. If the measurement is higher than 2 mg/l, use PhosphateMinus to reduce it. By doing it now, you’ll take away algae’s springtime food supply.
If you can’t remove mud during the water change, opt for SedimentMinus. This product contains bacteria and enzymes that decompose the organic matter at the bottom of ponds consisting of fish waste and rotting plant material. Before long, you’ll be able to see the bottom of your pond again. SedimentMinus can be applied all year round to break down sediment.
Aerate your pond with the new APK 400 pond aeration set. The processes of decay and the modest degree of plant growth in autumn means that the water holds less oxygen. An alternative to mechanical aeration is to use OxySafe. This product adds oxygen directly to the water. If applied once a week, you can be certain your pond is getting an ample oxygen supply. As well as high amounts of oxygen helping to strengthen fish immune defences, the same can be said of vitamins and minerals. Adding AquaFit creates a natural water regime while the vitamin B complex and active iodine, makes fish less prone to disease.
Leaves from trees and bushes can have a highly negative impact on water quality, which is why it is a good idea to clear them from the surface regularly, ideally before they sink. Choose evergreen trees and, most importantly, avoid poisonous plants when planting up the area around your pond. If the spot is too sunny, algae will multiply come the spring and summer.
