Also, I'd switch your Alk supplement to sodium bicarbonate right away and see if that makes the difference for you. I suspect it will.

I've retested after the lights have been on for an 1.5 hours & it reads 8.1-8.2 based on color. If I do switch to the recipe 2 Alk supp how will that help with the ca levels? Is it through the slightly lower ph that ca is able to elevate because of the decreased alkalinity?

Last winter it seemed the ph was lower. Which is why I had chosen the recipe 1 for the slight raising effect. & it worked until august from march all paras were spot on. How does the system just change Like that?

I will likely do this Thx.

Did you actually measure the new SW batch before adding?

Again as others said, dosing is to maintain what your tank consumes. After a WC supplement back up to your target levels and once you have matched your dosing to coral uptake, leave the dose settings alone.

just retested PH @ end of main lights out & it's at 8.4 so not much of a swing... maybe like .2-.3

So not so high, but on the higher end nonetheless.

Out of curiosity, do you have precipitate forming anywhere in your tank? Or was it just that the dosing solutions would precipitate when added to the tank?

[shrimpchips]

Try dosing less frequently, but more at each time to get around this double dosing that's going on.

BTW, I'm dosing over 2 ml/gallon of Ca and Alk. I think 3 ml of Mg/gal too

Micheal here are the pics of it. Incase they didn't come through on the email. FYI for anyone who has this it was super easy to take apart. The longest part was putting the pics to email/ canreef.

This does not show what we asked sorry, we need to see photos as posted here by us showing the underside of the ribbon cable connection and the front panel removed.

I can not offer support here, please contact me directly.

Here are pics of the front board removed & of the underside of the ribbon cable. I do not have tools small enough to remove the ribbon cable from the front, & therefor cannot take a pic. of the inside of the pinhole. However at this point i would say it is crystal clear there has never been a drop of moisture inside of this unit. Sorry I'm having now luck attaching photos to the email.
