My eba have laid eggs again they are doing this every 14 days now , I donāt have two tanks , my current tank is 500l so daily water changes to control hormone spikes is not a reasonable option , leaving them in my tank is not an option as it is home to 6 eba an Oscar and a pleco , iv saw and heard storyās of makeshift pop bottle breeding tanks with an air stone in the bottle , does anybody do it this way ? I have a 20l water cooler jug I use for small water changes and gravel vac , I do have a spare heater and air pump but I have no spare cycled filter , is beneficial bacteria really required if I change the water daily ?
