Is there a natural, stable way of increasing KH
In my 50gal, I have a pleasant KH
of 4, but in the 28gal it's <1. At least, the solution turns yellow on the first drop. I don't understand why they are different, I do everything the same in both, they both have plants and driftwood and gravel... bleh. It makes measuring CO2
levels in the 28gal very difficult.
50gal planted - yoyo loaches, BNs, odessa barbs, giant danios
33gal planted - praecox rainbows, gold ram, bolivian rams, sparkling gouramis, licorice gouramis, lots of shrimp
2 x 5gal planted - bettas
