dosing help

[makana]

I am using IO salt. When I tested a new batch it was low in mag and clac and I am now dosing it.

Interesting note is that a lot of the coraline has changed colour and some is flaking off the plastic.

What I don't understand is why my dkh was stable at around 7, never dropping, until I raised my levels. They seem to be out of balance but the measurments say they are balanced.

Could raising the levels have caused things like coraline or the tiny clam to start consuming more?
