Posted	r/o water
13-07-2007 20:17 by tucker	hi all,i have just bought a r/o unit,i want it for help in breeding my angelfish,wot i need to no is do you use 100% r/o water or 50% tap and 50% r/o water.thanks every one
13-07-2007 20:19 by netty d	My Angels breed without RO water, my tap water PH is 6.5. What's yours ?
13-07-2007 20:25 by tucker	hi my ph is 7 the water in stoke on trent is very hard and you can see the lime in it some times,the eggs always turn white with in 24 hours in tap water,its not the angels that are the problem as i can get them to hatch in rain water,but the problem is draging water in from outside to the living room isnt doing me any favers
13-07-2007 20:28 by sonia	what do you mean by very "hard" what are the readings? If the eggs are turning white it could be an infertile male or a male not "playing ball" so to speak and nothing to do with the water
13-07-2007 20:37 by tucker	i have 8 pairs,and can get them to hatch in tap rain water so its not a problem with the male,i carnt remember wot the hardness is but i use a meter the rain water is 24ppm and the tap water was over 1200ppm

Remineralising with some of your tapwater will give you more stable water conditions, better still tap off some water from the point before it enters the RO membrane and you will reduce the Nitrate that you are returning to the tank. It is my guess that eggs will hatch in 50% hard tapwater, if not try reducing it to 25% I have found that wild Mesonauta eggs hatch in a conductivity of 300ms (about 10 GH
