(isnt that a good reading for a good discus and ram added with a gold nugget pleco tank!?!?) but now im kinda stuck!! i havent performed any water changes yet so i am thinking about doing a 30% water change every week with that good ammonia free filtered fridge water and just adding a few chlorine eliminating liquid substinces to it..would i be doing a good thing by doing so?? or should i keep putting the harmful 0.50 ammonia tap water in the tank?? and also would that be a good thing to add the fridge filtered water with a new ph of 6.6 to my original tank water when i proceed in future water changes?? becasue im not sure what the ph would be if it was 7.0 and i would be adding new fresh filtered 6.6 water to it!?!? i just dont want to risk loosing out on a few discus due to them being expensive! do i just go ahead and do a 30% water change adding the fresh filtered water to the tank?? please help me out!! thanks!! i really wanna get my tank to par for discus/german blue/gold rams,and a gold pleco! and if anyone is wondering..my starter fish are 2 x-ray tetras and 3 red eye tetras... please help! original post: April 29, 2008, 2:59 pm sg8501321 2008-05-04 http://forum.aqua-fish.net/?topic=discus-tank-ph-and-ammonia-problem-help-me-plz-#2 o sorry i forgot to give you my whole test results... nitrate - 0ppm nitrite - 0ppm ammonia - inbetween 0.25 - 0.50 ph - 7.0 sg8501321 2008-05-04 http://forum.aqua-fish.net/?topic=discus-tank-ph-and-ammonia-problem-help-me-plz-#3 first things,I would not recommend tap water for discus at all.I purchased an HMA filter , which are quite inexpensive and they will remove all of the chlorines in the water.I cannot understand why you are getting ammonia from tap water ?? If you are going to use the fridge water ,check the GH -it must be above 4 or you run the risk of PH crash which will wipe out your stock. My advise would be to drain out your tank and start again with either HMA water or a mix of RO/HMA .Do not add any discus until the tank is well matured-6 months is the norm but depending on water quality you might get away with 4 months mickey 2008-05-04
