I'll be going away for a month and was wondering how to handle the fert levels in my 200l tank while I'm away.
Do I dose a lot before leaving?
Someone will be coming around but as they know nothing about tanks all I'll be asking them to do is to top up with water. I was actually thinking of mixing ferts in the top up water (will be in a barrel next to the aquarium) at a high enough concentration that when they top up with lets say 10 or 20l it would refertilize the tank.
Currently I fertilize K2SO4, KNO3, KH2PO4 and CSM+B at the weekly 50% water change and again mid week except for the PO4.
Too bad I haven't had the time to set up an auto doser! :? But even then I couldn't mix all the above together, especially the Fe and PO4...
How do you people do this? Or do you never go on vacations? :shock:
