Got chucked out of the house this evening as other half is having a girly night in - so I’m relegated to the pond sheds; real hardship.

Been neglecting the water tests just a little over the last couple of weeks, but had time on my hands..

PH in growing on tank 6.6, humm - KH nil. Ammonia is OK - so just caught things in time.

Now I have no excuse, things are nice, warm and dry in the shed, straight complacency. Message from this is that for those of you in soft water areas worth a little check on you KH and pH through the "winter" months.

Hiya Dave, don't you just hate it when that happens?

I assume from those readings that you were on the verge of a PH crash, yes?

Cheers...Freddy.

Hi Dave
Well Dave why has it got to that level? is it Straight RO and not mixing? How do you measure a nil KH would it that the water go's straight to yellow?

Yes Freddy it was the wrong side of the line.

But caught in time just a question of a minor adjustment.

There is a lean mix going in there, just slightly too lean

When the KH gets low you double the sample size to see if you get blue with a drop, if you don't then double it again..

The ratio of KH and GH in my supply is such that mixing isn't really the ideal solution - One of the tasks for 2012 is to change tack and use a pH controller and bicarb dosing to achieve the parameters I want - but that's another story.

Hi Dave
Yes I have seen a PH Controller set up and not to expensive and looks like it works well. with Mine Now the PH 7.1 and the Kh is 2 . Kh it's 5mil and it turns on the second drop this is where I am going to try and hold it if possible.

Hi Dave,

The main thing is you see it in time and although low and not ideal i am sure the fish where fine and still eating i bet

Ive had my tank to have a PH as low as 6 before now and the fish where fine still eating and where fine all i did was ad a bit of bi carb and things where all cool.

I suspect my small incursion into acidity was tweaking up the feed rates a couple of weeks back without a corresponding adjustment in the mix.

When you put your trust in a controller it needs to be reliable, so an investment in quality is worthwhile in my book.
