Dropping PH (GH results)
Ray,
thanks for your reply. What level of GH and KH should I have in the tank to avoid sudden PH drops? The current PH=6.6 is fine for my fish, but I’d like to add enough buffering capacity to keep the PH at the current or slightly higher level. My plan would be to add enough crushed coral to get to the right GH and KH. Also, do I need to replace the crushed coral over time with new one because it will get depleted or the same coral will work as long as it’s in the filter and does not need to be replaced?
Thanks and have a great 2009, Giuseppe
P.S. In the meantime my Kribensis gave birth to 20 beautiful frys
