How much KH do you dose throughout the day?

[SouL_Shaker]

I have 200 gallon set up. I dose around 60-85 ml everyday. Is it normal ?

How much do you dose per day ?

Ok what's KH

 

[twilliard]

KH is alkalinity in most tests DKH
I dose 2.5 Ml hr of a 2:1 mix of triton elementz #1

First off, KH is Karbonathärte, and it's German....meaning carbonate hardness.....a measurement of alkalinity. It might be listed as dKH....degrees or carbonate hardness.....and you'll want it between 7 and 11 or so....some like it higher.

As far as the OP's question, it sounds a touch low, but that's all determined by the amount of hard corals you have, the frequency of water changes and the volume of these changes. Just go by what you consume and pick a number you wish to maintain and keep it at that. I believe what's important is consistance.

How many liters in your tank ?

Calcium doesn't decrease very much. But KH and MG decrease very much. I change 200 liters every 20 days with red sea coral pro salt. I was dosing 65 ml per day. I bought a plate coral today. KH was around 7.7 . When I tested it decreased to 6.6 after adding plate coral. I increased dosing amount by 20 ml immediately. Am I right?

And this is my plate coral's photo

 

[twilliard]

My tank is a little over 300 liters

 

[Greenstreet.1]

75g display 30g sump/fug. 73ml a day.

 

[redfishbluefish]

So you're just starting with hard corals, so the numbers you originally posted are very reasonable. Continue testing and increase dosing accordingly.

 

[twilliard]

That's not bleaching in the center of your plate is it?

Bought the plate 2 days ago. The guy said it was damaged physically.

 

[Noremac]

90gallon display/55gallon sump, mixed corals. I only have to dose 30-40ml/day of 2part. the tank uses roughly .3-.4dKH per day.. Usually i dose it every other day due to my work schedule.

 

[oh207]

65g mix reef. 15ml/day

 

[SaltyBiker]

I have an SPS dominate 65g tank, with a 20g sump, and 20 gallon frag tank (105 total gallons) all plumbed together. I do a 15g water change every two weeks with reef crystals. I still only have to dose 15ml of KH per day. I'm a little suprised to hear some of the other folks having to dose so much and my tank is stocked packed full of stony coral.

I have 200 gallon. They drink KH like a water.

Heck I guess maybe it's the reef crystals keeping it elevated?

My salt is red sea coral pro. I change 200 liters water every 15 days. It doesn't help me out though. It just replaces the other elements like potassium.

 

[DaveJ]

450 total gallons, eats up over 400ML of alkalinity a day and just a touch more calcium.

 

[spsaddict]

260 total volume all sps. Currently dosing 275 ml of alk and a little less of calcium.
