Is my cycle truly finished, and is my KH a problem?
Been about a month on a fishless cycle, heavily planted. last week it was taking 48 hours after adding half a cap of ammonia to get to 0/0/40, now it is only taking 24 hours. Am I truly cycled or are the 40 nitrates a problem (it doesn't seem to move, but I do have Flourish Comp & Excel in the water, and Seachem root tabs in Eco-Complete). Some plants look great, others no s omuch (melting - transparent leaves. Not the Crypts either, Amazon swords of all things. Stems seem happy)
Are the nitrates OK? How about my other parameters?
Nitrate - 40
Nitrite - 0
GH - 75 (soft)
Chlorine - 0
KH - appears to be near 0
pH - 6.8 or slightly lower (which is a bit lower than my tap water)
Is the KH a problem? Any way to deal with that?
