Right, so think I will go measure the ph and see exactly what it is

I assume a good % water change each week will help with the ph as well? and lots of surface agitation?
I would so love not to have to remove the substrate for two reasons, one Princesscoral loves the colour (its pinkish) and two the mess

but if I MUST do it for the sake of the fish she wants to keep then I will. Going to wait to Tuesday (when lfs will not be so busy to go get some silver sand) and decide then as well as testing what the water is running out, PH wise, can i use my marine salifert ph test kit?
Thanks for all your help folks - it's amazing just how quickly you forget about things, it's been a long time since I had a freshwater tank! Been Brackish for many a year and marine for over a year now
anyways thanks a lot
