All for Reef Users: How much does your tank use?

[Randy Holmes-Farley Verified Community Expert]

8.2- also use a scrubbber

Then there’s no need for kalk, though it may be a cheaper option than the scrubber.

I spread mine out between 0830 (I think that is when I start) and 1700. I have tried a few other timelines and didn't see anything really different is why I was asking. I have not tried a single dose though.

Thanks again - hope your day is well.

I was single dosing in the morning for several months. I noticed no difference when I switched to a doser spreading it out over 5 doses. The only reason I bothered to add the doser was because I was forgetting to dose occasionally and I already had the pump.

Thank you. Appreciate that information!

I dose 18ml spread out into 4doses from 0900-1300. Alk has maintained at 8.5 and Ca 440. Don't test mg but I do a 3gal water change weekly which I'm assuming is helping things remain stable?...
Redsea 26gal.

290 mL/day in a 250 gallon... start to get costly...

I add also urea (for N) and iron.

 

[goosemans]

62 mL/day in my 48 gallon

How do you know how much urea to add?

How is your stocking? What do you attribute so much use to? Nice work!

90 gallon mixed reef with sps frags roughly 2-3 inches. Some LPS and zoas. Tank born torch that’s a fast grower and a small clam and I’m dosing about 35 mL give or take. Sometimes I need to adjust as it climbs or goes too low. But mag is an issue that I have to dose otherwise it gets too low

 

[Science/G]

8.7 mls daily on my 30 gallon mixed reef. I also dose 2 mls of Balling B daily to keep my alkalinity in line.

Why not just use more AFR to maintain alk?

40ml / day
250l SPS dom
4200ml kalk

How do you control your calc not rising too high?

I have quite a bit of cheap, fast growing corals and a derasa clam. Photo from 2 months ago. There’s definitely a huge relationship with higher pH and consumption rate

 

[Bohemian Waxwing]

35ml per day in my 60g breeder.

 

[Dragen Fiend]

25G IM lagoon- 5ml- dosed at night.

Keeps alk right around 8. I gave up on messing with PH. 7.8 at night to 8.1 lights on. May just add a refugium to boost it during night time.

I do a 1 gallon H2O change daily combined with tank consumption. This keeps my Ca level roughly 450ppm I’ve found.

I'm surprised at the difference in dosing with everyones tank. I have a mixed reef, lots of corals, 120 gallons total volume and I dose 24ml of AFR daily in 2 12ml doses. Alk is stable at 8.6 and cal at 440. I took my kalk offline but i'm planning on putting it back on. That'll likely drop my AFR consumption down by half.

I think sps will suck most, if you have many LPs and softies won't consume that much...
My tank have some colonies that probably drains my wallet with afr

I have alot of sps but no big colonies. I agree with sps having high demand. I would look into also dosing kalk. You’ll save alot.
