Alk help

[davidsalata]

I have a 120G I use BRS part 2. I dose alk and calk at 90ML per day. My alk drops daily. How much should I raise my ML per day? I have a lot of sps work strong growth.

It seems to of dropped from 7.8 to 6.8 in 3 days. Maybe the first test was wrong?

I just recalibrated my doser. The alk was at 9 now is back to 10ml calibrated

I’m going on a vacation for 11 days in 2 days. I finally fixed my doser been trying to get it right I wish I had more time.

Should I raise my alk to at least 100ml per day with the calk?

For what it's worth I've always had to dose more alk than calcium with my 2 part BRS solution. I'd start slow like you mentioned and see what happens...

There is a calculator for BRS product here:

Not sure what calk is (calcium? alkalinity? Kalkwasser?)

The small increase in dosing sounds right. It will be fine if alkalinity gradually goes up or down while you are away. In any case, don't try to raise up alkalinity in one big dose. That would be inviting a disaster right before vacation.

What is for you a lot of sps ?

Please post a full tank picture.

I am asking because a drop of 1 Alk unit in 3 days is a LOT. Or your tank really explode of SPS or you have a precipitation issue or your pumps stop for 3 days or something else.

A picture will be very valuable to understand what could "probably be your consumption " by people that use BRS 2 parts.

I use B-ionic 2 parts. But that is different. In my tank, that is pretty full, to have a 1 dkh decay in 3 days I probably have to almost stop the dosing pumps. BTW I never did that

This is my tank for you to have an idea.

On my two sps systems, one consumes 3 dkh per day, another one 3.5 dkh per day.
Both calcium reactors are “dripping “ like fire hoses.

As Dong said if you have that much of a swing you may be ready for a ca reactor.

I would slowly hand dose back up (in addition to the auto dosers) and then fine tune from there to accommodate the corals uptake. Also test at the same time of day. Otherwise you could measure at the lowest point one day and the highest point the next and over compensate.
