Raiseing calcium & Alk

How are you adding it? It's best to make a stock solution first, then dose that. If you're adding dry powder, you might be getting a lot of precipitate.

 

I measured 10tsp of part a calcium then added straight to display tank infront of power head, 10 secs later i measured 4 tsp of part b alk and added the same way

Its the liquid form.

 

When I manually dosed the BRS 2part I dose calcium in the morning and ALK an hour or so after lights out on the display. I dont know if that would affect you or not.

 

Why exactly did you do this, was you having the same problem and this cured it?
I will try just calcium in the morning theb test it and add alk later as you did

 

Help stabilize pH at night. Dosing alk can cause the pH to rise.

 

Update-
This morning i tested everything after adding 10tsp calcium and 4 tsp of alk
results are

Magnesium-1425ppm
Calcium-400ppm
Salinity-1.025
Temp-76f
Alkalinity-8
PH-8.0
Ammonia-0
Nitrite-0
Nitrate-0
Phosphate-0.02

I usually tested 12 hours after dosing with same results but testing 15 mins later i have perfect params, so am i actually using 20ppm calcium and 1 alk every 12 hours, i will test them again later

Thanks so far.

 

Stingray im having same probs. I make stock using 1litre bottle and r.o. water with salifert buffers and add quarter litre every morning. I found calcium and alk were fighting each other..get one up and the other came down??
I now dose alk for 4 days (1 litre) then calcium for 4 days round and round and it seems to work although tonights test after w.end water change show drop in alk

 

If you are not monitoring your magnesium that might very well be your problem.

 

Mag is 1360 - 1400 ??
