Auto dosers sound good but alot of work. I aint worried about gaining no growth in the time im off... just want everything to stay alive and algae free so that whem im back I can get it all growing again.
With next to zero nutrients in the tank except what the fish waste provides would the plants survive 2 weeks with just co2 and light without any adverse effects?
Is it worth mixing up 2 bottles worth of fertiliser? Combine all my dosage of
kno3 po4
so4
into one bottle and divide it into 4 bottles. Then get someone to pour the bottle in my tank twice a week for the 2 weeks im away?
The EI method is dependant upon the weekly water change to get rid of the excess at the end of the week.
I think you'd be safer off cutting your photoperiod and not dosing. You may have a little cleanup to do once you return, but you're probably better off than overdosing even more than EI already does.
What you can do if you have somebody to dose and do a water change, get the weekly pill dividers and measure out your daily ferts. You can do the same thing with food so the fish dont get overfed. Cheap, easy and foolproof IF you have somebody to do it.
