Cheers Tim, the ranunculus has taken really well in the tank. Spreading like wild fire, there may be some up as a freebie in a few weeks time.
@ Gary, cheers mate, they are kept in ro cut with a little tap water. The gh is about 8, ph is between 6.2-6.8, the tds sits around 100 ish. Lincoln tap water is hard as as well, ph from the tap is 8, gh 26, tds 450! Incidentally I was reading a study at work the other day regarding the link between hard water and aortic valve disease...there's something to look forward to! Lol
