BRS 2 Part: whats your schedule?

[Capt_Cully]

I'm going to be running a Ca reactor and dosing some kalk which is how I used to roll.

Until my reef takes off, I'm going to be dosing BRS 2 part. I may even stick with it depending on how it goes.

I've read the recommended schedule on their site.

BUT, I want to see what consumption rate people are experiencing in the real world.

Tank size?
Reef type? Softie, LPS, SPS dominated, or mixed
Where are you keeping Ca, Alk, Mg?
How much and how are you dosing all 3 components?

Thanks

90 gallon mixed reef
I use a Bubble Magus dosing pump and dose 60 cc Ca, 67 cc Alk, and 15 cc Mg daily. I also change 15 gallons/week with RC so that nothing swings too far out of balance.

Thanks for starting this thread. I'm also interested to see what people are dosing as I've little external referent.

about 200 gallons, SPS heavy, about 300ml kh&CA (should always be equal amounts). Mg has been holding steady so I haven't dosed

~90G total water volume mixed reef, very few SPS. During the winter when evaporation is very minimal I dose ~30ml kh and CA daily. Mg is only added when a water test indicates that it needs it. During the summer when I have more evaporation I just use kalk for makeup and make small adjustments if indicated by testing.

Great timing for this question, I'm tagging along. As I move everything to the ~250G system over the next couple weeks I'll need to figure it out all over again. I expect the evaporation will be more consistent year round with this system so I'm hoping I can do mostly kalk top off instead of 2 part.

Reviving this.

When do you dose?

 

[diablo30xp]

I dose cal alk daily at 9 pm everyday.....

 

[pascal32]

Dosing pump, dose is spread into 24 equal parts dosed every hour. Ca is 5 minutes after kh. Dose into return sections of sump which has a lot of turbulence for going through the over under trap

 

[Capt_Cully]

Would that create undue stress on the pumps over time versus dosing over an hour at night? One start, one stop. I'm not savy when it comes to electric motors an the stresses the sustain during starting and stopping. May be negligible for all I know.

I wouldn't worry about it with a dosing pump. The issue is that I dose quite a bit, putting close to 300ml into a 200 gallon system would swing the water parameters. That and the bubble magus pump makes it easy to break up into doses. I have found inconsistency from the BM pump when the doses get low, say < 5 ml.

When I had issues earlier in the year my dosing dropped to 80ml which I had at 4 or 8 times per day.
