I've been adding Alkaline8.3 to the tank to bring my PH level up to 8.3. The tank been stuck between 7.8 and 8.05 and won't go up any more. I have gradually been adding the alkaline8.3 as recommended, waiting it's 24 hours before adding more.

I currently have a 120Gal tank with a 35gal sump. I only added Tim's one and only bacteria and also added a small cleaning crew.

But I am getting a shipment today and while noticing the glass being covered with a white lining, I tested the parameters of the tank and the Calcium is 430, but the alkalinity is 300. I think this is what's causing the white layer on the glass. Is this going to be harm to the shipment that I'm adding in, it's mostly invertebrates, now can I lower the alkalinity and how can I get rid of the white lining on the glass, I can't even take it out with a blade.

Attached is a pic of the white layer on the screen..IMAG0327.jpg

how old is your tank? Has it fully cycled?

stop adding that alk stuff,

Why are you adding chemical buffers to raise the pH? I would stop using the chemicals and use more natural buffers if you really need the pH to go up.

I just saw a post that you got the tank last month 10-08-12. You do not need to add any chemicals at this time let it cycle.

doesn't sound like you should be adding ANYTHING to this tank. just leave it alone for a while. (that means AT LEAST another few weeks.)
