Sorry got a head full of questions today...!
Obviously a cheaper option than buying all LR.. our LFS (ha ha) said that it would be pointless to buy base rock as it leaches nitrates back into the water, they said that the only way to make sure it is ok is to place it in a bucket with a heater and power head and do regular water changes on it, testing the water every other day or so until the nitrate levels etc go down to 0. Now they reckon this could take a long time....
This method would cost money of course with all the water changes and over time would probably cost just as much as if we bought 40kg of LR ??
We were thinking of just building up the base of our new display with baserock maybe just 20 to 30 % of the total rock.. but now not so sure this is a good idea??
Any ideas please
