ESV B-Ionic Nitrate - 32oz - RECENTLY EXPIRED
RECENTLY EXPIRED ESV B-Ionic Nitrate Size: 32oz B-Ionic Nitrate is a concentrated source of nitrate in the form of a highly purified calcium nitrate solution. Overview of ESV Nitrate Additive Maintaining nitrate concentrations slightly higher than natural reef levels has been observed by many aquarists to be beneficial to coral health and coloration. This may be because higher levels of nitrate compensate for the lack of planktonic food organisms and particulate organic nitrogen available to corals in the wild.Biological assimilation and denitrification converts the nitrate added into carbonate alkalinity, so there is no accumulation of sodium or potassium, which are difficult to test for. Higher nitrate levels may also assist organic breakdown and prevent hydrogen sulfide in anoxic/anaerobic areas of rock and sand.When phosphate levels are already high, increasing food input can be problematic when trying to raise nitrate levels because food also imports phosphate. B-Ionic Nitrate provides a solution by raising nitrate without increasing phosphate. ESV B-Ionic Nitrate Dosing 1ml/20 gals. of aquarium water adds 1 ppm nitrate.

Dennerle Nano Corner Filter 40 - OPEN BOX/DEMO
USED OPEN BOX NO, FILTER ELEMENT PAD Dennerle Nano Corner Filter 40 The Nano corner filter is powerful with a pump capacity of 150 l/hour. At the same time, the pump runs so smoothly and quietly that it is practically inaudible. And the power consumption is also impressive: only 2 watts - that conserves natural resources. The water flow can be continuously adjusted and the water flow can be directed in any desired direction by the filter outlet, which can be rotated by 90 degrees. The filter has a nozzle tube with integrated cleaning slide, as well as a mini-brush for easy cleaning of the nozzle openings. Due to narrow intake openings and a very fine-pored pre-filter sponge, the Nano Corner Filter is also safe for young shrimp. Cleaning the filter element is child's play: simply grasp the filter at the outflow tube and pull it off to the front, then remove the filter element. It is best to wash out the filter element in a clean bucket of aquarium water to avoid damaging the important filter bacteria. Features of the Dennerle Corner Filter 40 Nano Compact Corner filter for freshwater aquaria Smooth and quiet operation Easy to use and easy to clean Water flow infinitely variable Filter outlet rotatable by 90d egrees Filter can be operated in horizontal or vertical position Dennerle Corner Filter 40 Nano Specifications Recommended Aquarium Size: Up to 40 Liters (10 Gallons) Dimensions: 100mm Wide x 195mm High x 60mm Deep (3.93" x 7.68" x 2.36") Power Consumption: 2 Watts Maximum Pump Capacity: 150 Liters per Hour (40 GPH)
