Ponds & LakesImportant Information-Please Read Before Treating Your Pond or LakeWater Changes When To Make Them?After Winter In the Spring it is always wise to do a gradual partial water change of 20-40%, this is because during the winter months with cold weather a lot of the ponds natural bacteria will die, also as the water cools their rate of reproduction also slows. Therefore the water will have a heavier carbon loading than normal which is not good for aquatic life. Before Using a Pond Treatment If you have used a different pond treatment in the last 6 months it is always wise to do a partial water change (10-20%) before using a new treatment. This is because different manufactures treatments have: Doing the Water Change Remember, do not change more than 20% every other day, this is to give fish time to acclimatise to the different water conditions. IMPORTANT INFORMATION - Oxygen Requirements For FishAssess your pond before using any water treatment - check levels of oxygen, ammonia, nitrite, nitrate, pH, general hardness etc. Many fish fatalities are due to lack of oxygen in the water, for example koi need 6 ppm dissolved oxygen at rest and higher levels when active, most ponds require 8-10 ppm dissolved oxygen. In all ponds, the biological filter and plants demand dissolved oxygen first and the fish survive on the residue, in most ponds supplementary aeration is vital to fish welfare. WARM WEATHER CAUTION!!- The higher the water temperature is the lower the level of dissolved oxygen present therefore in warm summer months adequate aeration is essential. The factors below all affect pond water oxygen levels. Do not shut pond pumps and aeration devices off at night. 1. Oxygen levels, derived from photosynthesis rise during the day when sunlight shines on plants and green algae in the water. Which Order to Use Hydra Products?When treating your pond with multiple Hydra Aquatic products do not mix products but use the products in the following order: 1) Quartz. 2) Crystal. 3) Water Dyes. 4) Bio Aquatic Bacteria Boost. 5). Phos-Gone. 6). Silt-Less. As with all pond treatments only use when you can observe fish - in the unlikely event of an adverse reaction. Always leave at least 5 days between adding different treatments to ensure the previous treatment has been completely exhausted. If using the Quartz and Crystal in the same pond do a 10-20% water change after using the Hydra Quartz. No need to do a water change when adding other products listed above. In lakes because the volume buffering capacity is much greater there is no need to do water changes. Hydra Crystal- Blue Measuring Spoon - 1 level spoon = 20g, 1 heaped spoon = 40g Hydra Pond Clear Plus - Blue Measuring Spoon - 1 level spoon = 30g, 1 heaped spoon = 45g Activated by water the product immediately starts to electrically charge individual algae cells so that they clump together. They either sink to the bottom of the pond where the filter system will clear them or float to the top. Best time to apply is late morning to early afternoon. Do Glass Test Before Applying To Pond Take a sample of water from your pond into a clear glass. Add a pinch of Hydra Product (as in pinch of salt) to glass and stir with spoon. The water will initially go cloudy then you will start to see clumps' forming as it pulls the green algae out of the water (within 30 minutes). Leave overnight and depending on product used you should be left either with fine sediment at the bottom of the glass or algae floating on the surface with the remainder of the water crystal clear. N.B.-If for any reason the above does not happen or the water remains brown, please speak to our Technical Helpline on 01908-265889 before using the product. During Treatment Ensure adequate aeration by water pump and or air pump. Remember an alga is adding oxygen to your water, therefore removing it will lower your oxygen levels. Allow plenty of time to observe fish - in the unlikely advent of an adverse reaction. Clean mechanical filters before starting treatment and keep these filters clean during treatment. Either dose Hydra Product at pump outlet, broadcast over pond surface, or dilute with tap water (do not use pond water) and add as a slurry. If powder floats on surface use hose with spray jet to mix into water body. In extreme cases if no improvement is seen - repeat application (after 48 hrs). Before retreating always take a sample of your pond water into a clear glass to check that it is in fact green and not simply suffering from suspended solids. Badly Fouled System - Dilution Rate 1:10,000 (100g treats 1,000 litres water). Second Application (if necessary) - Dilution Rate 1:10,000 Do a 10-20% water change before re-applying at above dilution rates. When To Use at Maintenance Dosage Use every 1-2 month at maintenance rate to keep pond clear of pollutants and toxins. Hydra Quartz / Hydra Lake Clear - Blue Measuring Spoon - 1 level spoon = 30g, 1 heaped spoon = 45g Treat ½ of pond / lake only, 48 hours later treat other ½. Remove blanket weed when it comes to surface. During treatment Ensure adequate aeration by water pump or air pump. Remember algae is adding oxygen to your water, therefore removing it will lower your oxygen levels. Allow plenty of time to observe fish - in the unlikely advent of an adverse reaction. Clean mechanical Initial Treatment Dilution Rate 1:10,000. (100g treats 1,000 litres water). Second Application (if necessary) - Dilution Rate 1:10,000. Do a 10-20% water change before re-applying at above rates (not lakes). When To Use at Maintenance Dosage Use every 1-2 month at maintenance rate to keep pond clear of blanket weed. N.B.-Do not use if the pond is clear of blanket weed (wait until it starts to appear). If you have to repeat any Quartz treatment leave at least 48 hours between consecutive treatments and change 10% of pond volume before subsequent treatment. ALL PRODUCTS - Heavy Scum Layer on Water SurfaceShould you have a heavy scum layer on the surface and the fish are showing any signs of distress, remove this scum and agitate the surface as much as possible. Either run all pumps including air pumps, raise air stones (if available) closer to the surface, play hose from height onto water surface to break surface tension of water |
