How much ALKALINITY in DKH does your tank consume per day?

[dentdominator]

1. How much dkh does your tank consume per day in 24 hours?

2. Total water volume? Just water, not aquarium in gallons.

3. What device do you use to add alkalinity? Calcium reactor, dosing pump, syringe, kalkwasser drip etc.

4. If using a solution how many milliliters per day?

4.. Coral load? Low, medium or high.

5. How often do you check your alkalinity and what level do you desire?

My tank seems to consumes 2 dkh in 24 hours. Total water 300 gallons. Dosing pump and trying to get levels dialed in right now using brs recipe #1 (214mls per day). Low coral load (small sps frags). Checking every 24 hours and would like 8 - 9 dkh.

That sounds like a fairly normal drop. I had tanks that'd drop that much per day just in coralline algae growth.

i have about 150 gal in total,id say that my coral load would be low to medium,but i do have a couple of hugh monti caps ,one is like the size of a 45 record and the other is getting there,my tank seems to drop 1dkh per day in 24 hrs,when i test in the morning its 7dkh,when i test after its done its like 8dkh.i use 250ml per day.of recipe #1.

[110galreef]

1. How much dkh does your tank consume per day in 24 hours?Not sure, just know what I dose

2. Total water volume? Just water, not aquarium in gallons.
Net volume is about 275g

3. What device do you use to add alkalinity? Calcium reactor, dosing pump, syringe, kalkwasser drip etc. bubble magus triple doser...BRS 2 part recepie 1

4. If using a solution how many milliliters per day?
36ml/day of ALK & Cal

4.. Coral load? Low, medium or high.
Med..~12 SPS med colonies, 75 frag, 2 clams & 12-15 softies & LPS

5. How often do you check your alkalinity and what level do you desire?
weekly, 8.5 dkh salifert

start w/ low dosing, if you start to high like me you will just precipitate & have off levels.

Not exactly sure why my dosing amount is so low, but hey it works......Cal has been steady at like 420-440 too?

 

[timi hendrix]

maybe its ur salt and waterchange husbandry.enjoy it if its low like that.i had to change from recipe #2 to recipe #1 because of ph and dosing amounts,but i like recipe#1 much better anyway.cheers and happy reefing.

That is a very low consumption. I'm using twice as much of something that has a higher concentration with half the tank size and half the coral.

110 reef... just curious... what SALT do you use??? whats your WC schedule?

110 reef... just curious... what SALT do you use??? whats your WC schedule?

I am using IO, and do just a basic 15% WC every 2 weeks. My dosing has been bumped up to 75ml of ALK & 70ml of CAL a day now.

params are holding steady in general, they may fall off a tad in a week, hence why I am now at 70ml's not the old 36ml's

Still is relatively low?! I have been above 50ml's /day for a good month or so now, seems I have been needing to bump up the daily dose about 5ml/day each week. But I do have tons of frag that are still growing, as do I have more & more coraline starting to take off

 

[evoi19]

Mine is VERY low for some odd reason.

1. How much dkh does your tank consume per day in 24 hours?
16ml/day

2. Total water volume? Just water, not aquarium in gallons.
just over 90gallons

3. What device do you use to add alkalinity? Calcium reactor, dosing pump, syringe, kalkwasser drip etc.
Bubble Magus dosing pump set to 16ml total broken out to 4 times a day (4ml every 6hrs)

4. If using a solution how many milliliters per day?
see above

4.. Coral load? Low, medium or high.
80% SPS 20% LPS/mushrooms

5. How often do you check your alkalinity and what level do you desire?
Check every 3 days. Alk is steady between 7.8 to 8.1 with a Hanna Checker

For some reason my tank doesn't consume much and I always wondered why because i have mostly SPS. All my SPS are growing fine and half of them are colonies and half are frags. I also do weekly 17 gallon water changes using red sea coral pro. I'm wondering if that may be the reason, but whatever the case may be, corals look good!

110galreef and evoi19,

That's in line with what my consumption is as well. The one thing we all have in common is the Bubble Magus (which I love by the way). I was rock steady around 10.1dkh on the Hanna with 40ml of two part set to dose 24 times a day. My tank size is a 240 gal. I'm starting to wonder if b/c the Bubble Magus can be set up to dose multiple times a day it keeps the parameters a lot more steady and therefore we need a lot less two part?

 

[cjcmcheek]

Without dosing I will get a drop of 2.5 meq/l in 24 hours

180 gallons

Calcium reactor, and minor adjustments bi weekly

I will dose 14-28 grams of sodium carbonate, calcium hydroxide, and magnesium sulfate as needed

Extremely high, I need a bigger tank

I test alk daily, ca daily, mg once a week

It may definitly help a little,

My tanks has seemed to steady for now as I just tested params and cal was 430 & alk was 8.6 so my 70ml cal & 75ml alk is holding everything right where it was at 10 days ago, if not just a tad higher!

You could be right there. It's interesting since i use more calcium than alk and I always thought it'd be the opposite. haha

 

[Reefer33]

I'm actually trying out the biopellets currently and trying to get my alk to fall to within normal seawater range between 8 to 9 dkh. I was noticing some STN on the tips of my sps frags so from what I've read the ALK is too high and burning the tips. My alk is falling SO slowly! I switched off my bubble magus just to get it to fall and on the hanna it's only dropped 10ppm over the course of 48hours. Of course all I've got currently are frags so they might not be taking up a lot of alk. Seems like it should be falling more quickly but maybe not?

 

[Randy Holmes-Farley]

The uptake of nitrate by bacteria can produce alkalinity, so if you start with a lot of nitrate, that might boost or at least slow the drop of alkalinity a bit until it is depleted. That said, your demand may also just be low

 

[dixiedog]

1. How much dkh does your tank consume per day in 24 hours?

This is the hardest question. I haven't thought about it in a while since my alk is steady. About .5 dKH/day I guess.

2. Total water volume? Just water, not aquarium in gallons.

30 gallons total

3. What device do you use to add alkalinity? Calcium reactor, dosing pump, syringe, kalkwasser drip etc.

Drew's dosing pump

4. If using a solution how many milliliters per day?

10.5 ml/day BRS recipe 1

4.. Coral load? Low, medium or high.

I'd say medium

5. How often do you check your alkalinity and what level do you desire?

Weekly; 9-ish

Ah, well that probably explains it then! Never would have considered that. It's probably a little bit of both I would suspect
