Who cares if the gH also rises? Not the zebras! Tufa, ocean rock, shells, or coral will all increase the buffering capacity of your water. Coral works best though. You can buy large pieces of crushed coral and keep it in a filter sock in your filtration to keep it out of sight. It really won't raise your hardness that much and will definitely keep your fish safe. These fish are not breeding discus. They won't mind gradually increased hardness in the slightest. I promise!

Somewhere with good water flow over and through the bag is important if your pH is really that unstable. If you add it and your pH is still dropping that's a good sign you need more flow through the bag

NO3: 10-25
NO2: 0
GH: 6
KH: 0 - 3
PH: 6.3 - 6.6
This could have been my readings, from the tap. It's dangerous to say, but none the less true, that spring and autimn is the time when my fish spawn. Why? Because it rains a lot there then, which lower the PH in the tap...
When that's said - - after I get babies I need to harden that water, or they blow up like balloons. See subject: "What's happening to my baby"
