Dosing Two Part

[onux20]

When I first heard about and started dosing two part, I was told not to dose together. Which I took as, don

I don't think what you're doing is a problem. For 2 years I'd dump in the dosages (approx 30-60ml) back to back for my Alk and Calc, all at once, and I didn't see any adverse effects in the tank. Once I upgraded to pumps, they'd drip into the tank at different times during the day, but I doubt if they dripped at the same time, in different areas of the sump, there would be any adverse effects. Droplets will disperse in that volume of water pretty fast I'd assume?

The potential negative is the solution "snowing" in the tank. As long as you don't see any precipitate I think you are fine. I seperate my dosing like 30 min from one to the next b/t alk and calc.

 

The main thing is to dose in an area of high flow (return chamber).

^or even into the DT itself (on a drip) in a high flow area... This minimizes wear and plating on the pumps and other equipment (e.g., heater).

I onyl see a small cloud when alk hits the water. Dissipates immediately, whci I undertsand as normal.

 

I asked because I was reading on another site that dosing one after the other cancels out their effectiness, something I had never heard before.

 

Thanks for the input.

Not sure about that. I dilute the b-ionic into 1/3rd strength and dose 3x as much. On my small tank this lets me make smaller additions throughout the day, and I find my levels are more constant.

 

I add like 40/ml a day (but that is my diluted version). I know some people have to add 100's of ml a day undiluted...

[onux20]

Not sure about that.

 

Not sure of the cancelling or clouding?

Cancelling... I do not know if it cancels or not. I can't see how it would?

If the two are dosed in a way that prevents them from reacting- such as in two seperate high flow areas you should be fine. if it is snowing(precipitating) though it is forming calcium carbonate which is just going to settle to the bottom of your tank and not add to the free calcium or carbonite in solution.

If you are dosing substantial amounts then I would personally either sperate the dose location or find a way to offset the dosing by 30min or so. you could dose one to the sump and one to the display. on the other hand if its only a few mils then I wouldnt worry about it.

Question guys. If dosing two part from BRS how many ML in 24 hours with dosing pump?

Let say Cal is 420 and Alk 9. Thanks

It depends on where you want your levels and your tank volume.

 

BRS has a handy calculator here:

The BRS pumps are 1.1 mL/minute.

 

At the bottom of this link, they have recommended starting amounts for daily dosing:

So for a 200g volume system, for example, you might want to start daily dosing around 200*0.6=120mL/day, which is running the pumps for 109 minutes per day.

...and what your demand is for each supplement.(which will change as the coral grow) You would need to calculate the change in values over a set timeframe, say 24-48 hrs. That will identify your tank's demand for each supplement. From there, you can determine how much you need to dose in order to meet that demand and then raise to the values you want to maintain.

 

So if after 24 hrs your Alk dropped from 9.0 to 8.0. You can then determine how much alk to dose to raise your alk 1dkh based on your volume. Spread out over 24hrs, will give you your dose rate. Same for Ca.

 

Love the BRS calculator.

Let say 180g volume and the cal at 420 and Alk at 9 how many ml needed to dose in 24 hrs.

I have a bubble magus doser when I set it 500ml in 24 hrs and it's dose 31 seconds every one hour. But 500 ml a day look like alot.

Don't forget your sump and other systems too, they count towards the total volume. What size is your sump? Do you have any other tanks connected to your 180g?

Just the sump. But alot of rocks so I'll say total 180g.

500 ml of cal and 500 ml of Alk seem like alot for a day. Just curious

According to BRS, 1mL/gallon = "Numerous full sized SPS colonies and clams" - so that would be 180mL/day. 500mL/day seems extremely high unless your 180g is jam packed with demanding SPS colonies and clams?

[Alieu07]

I only have two clams and some SPS frags. I need to reset it.

[Alieu07]

No wonder 1g jug only last for one week

Yes, I think so! I would recommend dropping to 100mL/day and see what your levels are after a week.
