Fergy666 Posted October 1, 2013 Report Share Posted October 1, 2013 (edited) Hey guys, Just tested my water with an API Master Test kit 2 days after doing a water change and my parameters are as follows Ammonia - 0 Nitrite - 0 PH - pushing 8.0-8.2 it seems Nitrates - pushing 40ppm Previously the tank was running at around PH - 7.4 Nitrates - were around 5.0ppm after introducing Purigen. My concern is the rise in the PH as well as the higher than usual nitrates 2 days after changing 25% of the water Tank is 25Litres with Red Cherry Shrimp and a Mystery Snail running Aquaclear HOB with Seachem matrix (and original bio) and purigen Water temp is up from about 25-27 with the current hot weather here. Should I be concerned at these levels? I recently started feeding the shrimp daily, rather than every 2nd day, could this be the issue and should I go back to this? Any ideas are appreciated. EDIT: Water is straight from a Water Tank also Edited October 1, 2013 by Fergy666 Link to comment Share on other sites More sharing options...
