“frequent, trustworthy water changer”…
I wouldn’t have answered you Peter, if that part would have been in the last paragraph you wrote! 😉 But you came clean afterwards, so here I come;
For my 20 litre Paro-tank I change up to half of the aquariums height every two weeks. But I don’t have specific day for doing it, so it’s only aproximately.
I use tab water, please don’t crucify me! In Brunswick it is really low in carbonates by nature, I then add some humic substances by using peat and drop down the pH using oak extract to about 4.5 pH.
-> no carbonate hardness measurable and the eggs stick and evolve good.
Unfortunately I got some problem due to evapotranspiration, because after two weeks the water level has fallen by about one quarter. It happens because I don’t have a 100% fitting, clear cover, so I only close it at night when I have to keep my window open (so I don’t suffocate by lack of oxygen). I’m a little concerned about the rising concentration of Ions, but I hope the many plants take care of it!
Dear Sverting, what are “java snails”?
