Shrimpie Posted December 13, 2014 Report Share Posted December 13, 2014 Tank is 3 months old. Shrimp (crs, goldens & red rili) have been in the tank 3 weeks. Time for the first water change. Tank parameters are: RO water GH 6 (would like to get it down to 5 eventually) KH 1 PH 7.1 Temp 74 Ammonia, Nitrite, Nitrate all 0 TDS 183 (would like to get it down to 150 eventually and very gradually) I remineralized my RO for the WC to 150 TDS and 5 GH But my RO is at 5.8 PH in the replacement water - I don't want to shock the critters - will a 5% or 10% water change be okay at that ph? I will drip the water change in behind the Hamburg Mattenfilter. Thanks for your help everyone. Quote Link to comment Share on other sites More sharing options...
