Ok, silly question but i need to know! Water changes have been very simple in my fish only marine set up so far. However, having added some lovely mushrooms and a leather coral i'm unsure if i need to move them to a lower position in the tank when i drop the water level? Can they be exposed to air for any length of time? (i.e. when doing a water change)
Hi there, Yes you are right, the paramerters change a lot more quickly in a smaller environment than in a larger one. I would recommend a 20% water change once a month, but in the smaller tank, you could for example do "little and often" eg 10% a fortnight. Best to move the corals and mushrooms down a little (as you have already said you would do)but odd moments out of water aren't fatal.
