How much Alkalinity and Calcium 2 Part are you dosing?

How many gallons of water are you treating?

How many corals do you have and what types?

 

[revhtree Verified Admin]

For me it's the following:

1. 375ml of each

2. 425g

3. Mixed.

12 LPS (small to medium colonies)
23 LPS Frags
5 Soft (small to medium colonies)
11 Shroom Frags (26 Heads)
22 SPS Frags
1 Medium Cap
27 Zoa Frags

 

[BrettMallette]

1. .23dkh/day of reef carbonate by seachem
1ppm ca/day
15ppm mg/day (raising magnesium currently)

2. 55g no sump

3.mixture of everything fairly stocked tank of corals. More lps than sps but also have a massive teardrop maxima

 

[Mirkus]

Brs 2 part

125ml for ~100g sps tank.

Brs 2 part

125ml for ~100g sps tank.

How stocked?

 

[Maacc]

For me it's the following:

1. 400ml of each

2. 425g

3. Mixed mostly LPS. About 20 smaller LPS corals. 5 small soft. 20 frags. 10 sps frags. Medium monti cap.

That seems a little high for maintenance new and lightly stocked. Are you sure you aren't precipitating somewhere? But if not, sounds like a a calcium reactor is in your immediate future.

 

[nemo1017]

1. 22 ml of calcium and alkalinity via BRS 2 part
2. 50 gallons
3. Sps/lps and a few soft corals.

 

[reef80]

BIonic 95ml. Heavy stock 100 gallon sps only...

 

[kashman100]

1).75 ml per day
2). 100 gallons
3). Medium sized Lps colonies and a lot of various frags

 

[pa1ntbru5h]

1. Currently at 18 mL per day, but slowly rising due to SPS finally taking off (ESV B-Ionic 2 Part)
2. 80 gallons total
3. Mixed reef with lots of frags

 

[donnievaz]

7.5 ml ESV B-Ionic 2 Part a day except when I miss a day
29 Gal
Mixed reef approximately 20% Soft, 20% LPS, 40% SPS

 

[AdamNC]

1. Alk 35ml/day, Ca 26ml/day

2. 29 gallon tank, 20 gallons volume

3. 90% SPS, 3 Zoa colonies, A Duncan and an Acan.

How stocked?

Here's my tank.
I think 400ml sounds a bit high too. Sounds like it is precipitating. I had that happen to me before. I was putting 200ml into a 55 gallon tank. Turned my sandbed into a brick.

 

[redfishbluefish]

I'm using Dr. Randy's DIY recipe, which is the same as BRS.

1. Between 55 - 60 mls / day....targeting 7.5 dKH.
2. 90 gallon DT with a 40B sump....guesstimate water volume at 110 g's.
3. Old established mix reef with 75-80 percent SPS/LPS colonies.

My tank was getting hard in the beginning but has been fine for a while.

 

[alten78]

BRS 2 part - 75ml day alk targeting 8.0-8.5

75g w/30g sump

SPS dominated, few med size colonies, 20 1-3" frags, few zoas, few lps.

 

[Holy_makerel]

Reef fusion 2 part

10ml alk

8ml cal

kalkwasser 240ml

Hand dose mag every few days

32 gal lots of SPS and LPS. several acros, 5 montis, stylo, birdnest, acans, fungia, lepto, frogspawn, 3 chalice, cyphastrea, zoas, and shrooms....probably missing a few.

Still adjusting my dosing to suit my tanks needs.
Perameters as of 3-26-17
Alk 7.5
Cal 360
Mag 1250

 

[Ocelaris]

I know I'm probably precipitating, but I'm up to 220ml alk (sodium carbonate) and 200 calcium for a 110 gallon with 30 gallon sump. It's mostly sps frags and I few colonies (probably like 40). I've tried resetting a few times and measured what it takes to keep alk and calcium up, and if I lower the dose it just keeps dropping, so at some point I have to reset again and find the stable levels. Growth is great though. I'm using brs two part and brs dosers on an apex. I try to keep alk around 10 and calcium around 440, magnesium at 1400.

 

[Frop]

My little 10 gallon? It have like 7 Frags, 1 is a monti. Alk never changes. I don't bother to check cal/mag but I don't think that really moves either...

So to answer your question, nothing just water changes for now.

Thanks for starting this discussion. I had been doing some digging looking around for a centralized place to discuss this and I think this is the place!

How much Alkalinity and Calcium 2 Part are you dosing?

• Alkalinity - 0.294 dKh / 31.5 ml of Soda Ash Daily
• Calcium - 2.05 ppm / 31.5 ml of Calcium Chloride Daily

How many gallons of water are you treating?

• 120 display + 55 sump = 150 gallons water volume

How many corals do you have and what types?

• 19 Total - Smaller frags
• 2 Softies (palys, zoas)
• 6 LPS (euphyllia, fungia, caulastrea, duncan, cyphastrea, etc)
• 11 SPS (acros, montis, pavonas, birdsnests, psammocora, etc)

I'm adding 8 new sps frags and 4 chalice frags today. I'll check back in the coming weeks to update how much of an increase in dosing I'll have to implement.
