Hey! So I check GH and KH and they are at 5 and 10. Which is normal for water!
There is no 'normal'.
What units are using?
Wood does not raise pH. (drift wood, manzanita or anything else).
Water company may be adding something to keep the pH up.
But a KH of 10 German degrees of hardness (if that is the units you are using) is enough to keep the pH up even if they were not adding anything.
Buy or make your own reverse osmosis filtered water and add just the minerals the fish want. I did this for my Rams, making the GH and KH about 2-3 German degrees of hardness, pH about 6.0, trace of tannic acid from peat moss. They bred regularly.
Here is a test you can try:
Buy 1 gallon of RO or distilled water (they are about the same as far as aquarium keeping goes).
Make a few recipes and see what happens.
25% tap + 75% RO
75% tap + 25% RO
See which has a KH closest to about 3-5 German degrees of hardness, and what the pH is of each of these. Work with the one that makes the pH about 6.5-7.5
Add Seachem Equilibrium to bring the GH back up to equal the KH. (difficult to dissolve- add a bubbler or small pump, or stir frequently for an hour or so)
Add a handful of peat moss and stir. Let it sit overnight, or keep the bubbler/pump running to keep stirring the peat moss.
GH, KH, pH.
If this is not quite the recipe you want, then go back and try a different blend of RO + tap.
When you find a recipe that works:
1) Prepare water for water changes this way all the time.
2) When you are first changing the fish over to this kind of water do small, frequent water changes, such as 10-20% twice a week. Do not drop the GH and KH too fast. Allow the fish a chance to get used to the lower mineral levels.
