Where is all the alkalinity going in a fish only?

[cracker]

so, I have a 180 fish only with 5 fish & 2 Soft corals ,a toad stool & Kenya tree.
Dispite the ato with full concentration of Kalkwasser & 25 to 30 mls of parts 1 & 2 I can barely keep alk in the very low 7o,'s If I miss a day it drops to mid 6's every time.
I can keep dosing this but trying to figure out where it all goes. Or am I over reacting .
There is very little hardening of the sand bed. Nothing to consume it. I dose the alk every day equal amount if Ca every other day can answer just about any question You have.
Any ideas? Thanks !

Any coralline algae?

Not much at all,hold on let me take a look, No just some on the rock.

Anybody else?

Follow up question, what test kit are you determining your levels with?

If you have snails, they could be growing their shells and consuming ALK.

I have redsea kits for No3, Ca & mag, hanna's for ULRr Po4 & ALK.

I have a lot of snails in there.

I have a lot of snails in there.

Off track, but about how many snails?
Are you still in an ugly stage with this tank?

We have a 75 gallon tank.
I can't keep alive more than 4 turbos, 5 trochus, a money snail, and maybe 5-6 smaller remaining hemit crabs.

Always wondered how people kept more than that.

If nitrate is rising, alk will deplete.

There are also many organisms the use it. Snails, coralline, certain worms, urchins etc.

@norfolkgarden , I need to quantify the snail numbers there are around 30 snails . When I see a little more algae I ad more snails . I guess I meant a lot for the amount of algae in this tank. Iv'e not really seen a big ugly stage. Some diatoms & cyano that has since disipated. The tank,180 gl has been going for almost 2 years

No precipitation? How’s your mg level?
I have about the same amount of snails plus probably 20 hermits, and a golf ball sized pincushion urchin with just a bit more water volume then you I’m now dosing 36 ml of each 2 part and 1500 ml of kalk a day. I only have 3 small SPS frags the rest are leathers and euphyllia and I had to bump up my doser after today’s testing. Oddly I’m also losing 10 ppm of mg a week as well. And up till September I hadn’t had a change in mg lvl since last April my book shows.

I test just to night aks 6.3 ! Didn't dose today. 35 is about what I need to keep it at low 7's
