I kept several tropical tanks in the 70s & 80s. Things have changed a lot since then so I'm swotting up on current info etc.
With retirement this year I've been bitten by the bug for fishkeeping again.
Northumbria Water have a list showing the various parameters for their water:
Nothing for the Calcium content, Nitrates seem low.
Again my area in Gateshead is listed as "Slightly Hard"
Has anyone removed the filter & fitted it back on the left side of the tank?
I'm thinking of getting the Rio 125 & the left side of the tank will be against a wall so having the filter on this side would be better.
The filter box will need to be turned 90deg so the blank side are still...
