Hey guys im freakin' out. I have a 150 gallon tank and a 40 gallon sump setup. ASM G4 Skimmer and Eshoppes AVD 300 Sump/Refuge Setup. I am running into a ridiculously high KH
level. All other areas check out and I have performed many water changes to lower it. The reading of my tap water for changing is sitting at 120mg/L. I test every 5 days and the readings I receive have not altered much over the last 30 days.
Calcium - 440-500mg/L
Nitrate - 20-50mg/L
Nitrite - .1-.4mg/L
Ammonia - .1-.5mg/L
Phosphate - .25-.5mg/L
PH - 8.1-8.4
Is there a problem with such high levels of KH
. My test kit says that it should be kept between 105-120 and to contact LFS
if above 130. I did and they said change water. I have done so with no change. I dose Purple Up 2 capfuls a day. I do not add anything else but do have chaeto refuge mud and also 100 lbs liverock. Please any help. I dont want to lose any coral bc a level is off and I can not seem to find an answer. Thanks.
