Thanks Purrbox, if we ever meet up I'm going to give you a big kiss! I love your tanks as well, you are a constant source of inspiration for me, your sense of scale and choice of plants always blows me away.
Thanks for the advice Wiz, and no pleco's for me! At least not in my planted tanks! I do have an 8" sailfin plec in my 45 gallon hex, the plants in there are all fake silk. He's happy in there.
The water in this house is exactly the same as my old place, I moved just down the road. Kh is 18, GH is off the charts. That's using the Hagon kit, all I've got at the moment. I'm using a drop checker to keep an eye on my C02 levels, have been using one for some time now, had it in the old place. It's quite acurate, like doing a constant ph test. Judging by the colour of the regent in the drop checker in the 75, I could still use a bit more C02.
