Hydrogen peroxide fish tank oxygen

Hydrogen peroxide is a rather unstable molecule and in light, will quickly turn into oxygen and water. If you didn't add more than a couple of ml, your plants 'death' is likely to be due to the plants tissue not being healthy and reacted to the peroxide. Sixty ml of a 3% hydrogen peroxide solution are slowly released over the affected area with a syringe (needle detached of course). Three such injections were made in the tank, one of them used exclusively for the heavily covered M.pteropus. Within seconds, bubbles of nascent oxygen are visible on the algae. Bill: I added some hydrogen peroxide to my fish tank to remove some black algae. The problem was I did not know how much to add. I turned the filter and air off to stop the current in the tank. I put in about 60-70cc in a 20 gallon tank with a 20cc syringe injected directly on the black algae. Waited about 5 min and started the air and filter. If you are using 3% hydrogen peroxide, each 1 ml added per 30 Litres (8 US gallons) will increase total peroxide levels by 1 mg/l. 15 mg/l per 48 hours is thought by many to be a fish safe concentration. As an oxygen aid [ edit | edit source ] In the case of green algae: 25 to a maximum of 35 ml of the 3% solution of hydrogen peroxide per 50 liters of water. In order to calculate the dosage you need for your aquarium, divide the gross volume of your tank by 50. Discontinue all aeration before adding Hydrogen Peroxide to the water. Using a syringe or pipette, add 3% Hydrogen Peroxide as per dosing instructions below. Dip the tip below the waterline and spread the H 2 O 2 throughout the water. (Do not allow any air/bubbles to enter the water at this point.)
