Bottom Sludge

Soil sludge products accelerate the biological removal of slowly degradable organic soil sludge that can become toxic to fish and plants.

Velda Bio-Oxidator - 5,000 ml
Velda Bio-Oxidator - 5,000 ml
Leaf litter, plant remains and fish droppings can seriously contaminate the pond floor. Especially under low-oxygen conditions, the bottom layer will acidify and bacterial conversion of organic bottom sludge is no longer possible. This seriously affects the pond environment. The aquatic plants stop growing and algae take over. Bio-Oxydator removes pond bottom sludge and prevents new sludge formation. Available in packs of 1000, 2500 and 5000 ml. With the help of three active ingredients, Bio-Oxydator tackles the bottom sludge: The pH-regulating granules ensure that the soil layer does not acidify. The slowly dissolving natural lime ensures the correct water hardness in the bottom zone. The added micro-organisms (in freeze-dried form) immediately start the bacterial conversion of the soil waste. With Bio-Oxydator, the bottom sludge will disappear in a short time. Apply mainly in early spring and autumn.

Microbe-Lift Sludge Away - 4 Liter
Microbe-Lift Sludge Away - 4 Liter
Ensures rapid & natural decomposition of bottom sludge 80% faster than comparable products Binds phosphates Helps to clear the pond water 100% active ingredients Distributes quickly in the water Biodegradable Microbe-Lift® Sludge Away accelerates the biological removal of slowly degradable organic bottom sludge that can become toxic to fish and plants. When organic particles build up on the pond floor, they begin to rot, releasing toxic gases. These gaseous by-products endanger pond life. Microbe-Lift® Sludge Away removes organic bottom sludge - reducing or completely eliminating the potentially dangerous gas formation - and it also helps to clear the pond water. Sludge Away is particularly suitable for ponds with a substrate bottom and where bottom suckers are difficult to use. Works faster in warm water temperatures but can be used all year round. Dosage: Basic dose = 100ml per 1250 liters of pond water. First month 100ml per 1250 liters of pond water per week, then 1 x per month (if necessary) 100ml per 1250 liters of pond water. TIP! Sludge Away is ideal for fully automatic dosing with the AquaForte DosaTech dosing pump.

AquaActiv SediFree 500 ml
AquaActiv SediFree 500 ml
Especially in areas with little circulation, sludge and sludge layers are formed in the garden pond from dead algae, leaves and plant remains. These can cause putrefaction and other unpleasant odors. In addition to regular cleaning with a sludge vacuum, you can gently remove and prevent deposits with SediFree. The granulate with active oxygen sinks deep into the sludge layer and oxidizes it. In this way, specialized micro-organisms take care of the decomposition of organic material. For a quick effect, we recommend application at a water temperature of 10 degrees or more.

Sera pond filter biostart
Sera pond filter biostart
Concentrate of highly active micro-organisms and enzymes that prepare for nitrification and reduce mud through the decomposition of organic matter. The mud on the bottom is caused by, among other things, dead plant remains, leaves that have fallen into the water. excrement from the fish and food remains to maintain the biological balance in the pond it is important to remove the sludge on the bottom because the mud causes an oxygen deficiency at the bottom of the pond. Subsequently, the smallest living creatures that break down organic matter die off and through putrefaction processes hydrogen sulphide is created, which not only creates an unpleasant odor, but also affects the gills of the fish. Dosage: 250 ml per 10000 liters of pond water
