Hi

Thanks for your replies. I have a few questions-

My tank is heavily planted (without fish), dosing schedule listed below. I believe I have a C02 bubble rate at about 1 bubble per s going though my external filter intake valve. I have found although my java fern, moss, hygro and various cryps all seem to pearl at a greater or lesser degree, my ricca and Eleocharis parvula seem to produce little or no pearling throughout the day, would you suggest more C02 is needed? Also what duration do you suggest reducing my lighting by?

I have also found some of my cryps have melting leaves and some of my hygos have turned slightly clear at the leaf edges, is this common when they have been recently planted due to the stress of planting? Would you suggest pruning back these leaves?

I have tested my water again today at roughly the same time, early afternoon, before dosing, the light having been on 3h aprox, with the results listed below. Due to the decrease in PH and KH and at Tom’s suggestion I will change 50% of the water this evening and add activated carbon. However what would you suggest I dose today as I am only 1 day into my dosing regime, trace, or more KN03 & KH2P04 removed by the water change? Does the use of activated carbon mean I need to add larger amounts of ferts; does the activated carbon absorb some of them out of the water?

Thanks for your time.
Regards.
