10g nano... Kalk, 2 part, 3 part or awc?

[fr3n0z]

Hi guys, i am a bit unsure on how to proceed. I would like to keep dosing my nano (still lightly stocked, 10g tank with frags: 8 soft, 1 lps, 4 gorgonia, 5 snail, 1 shrimp, 2 fish, 1 anemonek, chaeto reactor) in order to reduce at max the WC (montly or 3weekly would by ideal).

I have ATO and 4 head doser.

I have dosed for the last 3 weeks tropic marin 3 part + the 3 oligo element, no water change for 3 weeks. BUT Instead of tropic marin ALK part i have dosed randy's recipe with soda ash to keep up the PH.

Params were good (was dosing very lightly...like 0.25dkh, 2ppm Ca and equivalent in part C) but MG got quite high (1500) while KH and CA we're going down.
Started at 9dkh 480CA and 1320MG 8.4ph and after 3 weeks we're 6dkh 300Ca and 1500MG 8.4ph.

I think in 3 part tropic marin MG is already inside one part C, i should up the dosing to keep up with CA and alk but i'm scared MG will go even higher.

4 solution i see:
- start dosing kalk with doser and montly WC will replenish the rest.
- keep dosing 3 part tropic marin and reduce part C
- 1% daily AWC and no dosing
- move on a 2 part and monthly EC will replenish the rest

Or any combination of those ways. What do you guys would do?

Thats a lot of thinking, testing, dosing, and daily hands on just to avoid a 5 minutes water change on a 10 gallon softie tank.

I agree with @LordofCinder

I am all for overkill, but I'd just dose All for Reef if I dosed anything at all.
