How to lower KH??

My KH is 11 dkh or 197ppm, Is there a easy way to drop this down? I know if I use RO water with my next change it should but is there any other way?

 

Why do you want to lower that? I keep mine between 12-16 That sounds good to me. Luna

 

My API test kit tells me I want it at 5-7 for "Natural Sea water"

 

IMO soft corals like 7-11KH and Hard corals like 11+KH. Sounds like you are fine no matter what you have.

 

what is your Ca? Mg?

 

I personally wouldnt change a thing, but thats just me. But if you want to lower it anyways, vinegar will lower it and raising your Cal levels will too. Luna

 

My Cal is at 580 Mag I need to get a test kit for still my LFS was out today.

My water is as follows

Fish Tank Parameters
Ammonia0ppm
Nitrites0ppm
Nitrates15ppm
PH8.2
Cal580
KHDkh 11 or 196.9ppm

 

with Ca at 580 you actually need to raise the dKH, 20:1 ratio, you should have 29 dKH. both of which are too high, you max Ca shouldnt go over 500. you could add some dKH to lower the Ca, whats your Mg?

 

I dont have a Mg test, fish store was out today. She told me tuesday they will have one.


Everything seems to be fine animal wise that is, Corals open all the way up and are growing. Fish are all doing fine and eating well, My Hydrometer reads I am a little low on that as well at like 1.21

 

1.21 is high, 1.026 is better.

Mg is the buffer between Ca and dKH, Ca and dKH dont play well together.
