Hi all
Just wanted to pass on a bit of a warning re open top tanks, glass outlets and evaporation. Having rescaped my 4ft over the Easter bank hols, I had to go away from Wednesday until Sunday. During this time the water level in the tank dropped by around 2cm (dont ask, I'm sure I filled it up before I left) to the point at which the glass outlet was poking out above the waters surface. That created masses of surface movement (as you can imagine) which resulted in a very blue DC. For how many days I dont know, but the tank is now covered in brown thread algae and the plants look crap due to having been forced to work by the high light but without the CO2 to cope with it.
Don't make the same mistake I have.
