Gday fellas, tested for potassium to get a baseline. Found mine to be spot on 400.... (If that's baby blue enough).However did see the solution in the vial was a bit chunky like off milk during the process. Is this normal?
Ps thanks @slin1977 for getting me onto this and all the advice

We are aquatic gardeners right?
Gardeners know the importance of the big three and how they affect the growth of roots to the yield of thier flowers or fruit. The NPK ratio is on all fertilisers.
So keeping potassium levels right is important as you loose potassium with Zeo stones , skimming etc etc.

Testing every three to four weeks will give you an idea of potassium consumption.

Yes the milky residue on your test kit is normal.

Normal mate, as @slin1977 said keep an eye on it from time to time, It more important for SPS corals to maintain colors.
in time the test tube will be hard to clean however a little vinegar bath will clean it up.

Just confirming that I get the same and a vinegar wash after each test keeps the tube nice and clean.

Yep, same as above. Have fun cleaning the vial :)

Yer, sometimes I leave the vinegar in for a week and it makes no dint in that white scale left on the vial.
