thanks. oh and btw, my stargrass came (big thanks to dewalltheway). i gave it a good spot under the lighting temporarily to get it growing and help give it a little head start.

my kh is falling. i dont know what is doing it. it was 3, now its 2. and it is bringing my ph down with it (5.8). it was happening like this in my old tank too, and i have no clue what is doing it.
it cant be bacteria, or decay, not this fast. the colonies cant build up from a washed filter and new unused substrate in under 24 hours.
its not my tap, because i left my ph controller in a cup overnight, and its ph and kh did not fall.
i will use baking soda, but i really want to get my tank to stabilize rather then keeping it up on life support.
