comments on external filters
#1
I am considering buying an Eheim external filter.
Either the Proffesional II or the Wet/Dry. Both of these could be bought with a thermometer and heater.
To add the heater to each unit ups the price by £90.
Has any one got any comments on comparing the Proff II against the Wet/Dry?
Is it really worth £90 to have a heater in the filter and not a cheaper one in the tank?
Any comments would be appreciated.
