Ok retested some water I had left sitting. PH remains the same. Tested Nitrate again and this one seems to be around 0-5ppm. Think the fact I checked results last night in artificial light made it look darker. Checked today in daylight and it looks yellow rather than orange.
Im going to do a few more nitrate tests over the next few days, see if it makes a difference whether it is tap water or out of the hose etc.
bought the eheim 200 pump,it's great. v quiet, power controls and does 2 stones. got good deal. £18 from zooplus. you get a discount coupon with 1st order would recommend the pump.
Was dead set on a red cap oranda, but like the look of the calico red head oranda. And second fish will be a ranchu, red and black or red and white.. decisions, decisions.
