New Tank - LOW ph!
I filled up my new 29 gal tank yesterday. I laid down 2.5 bags of eco-complete as substrate. The Wisper 30 power filter has been running full speed for the last 24 hrs. Just now after coming home from work, I did a ph test and it showed 6.5! My tap water is coming out with 7.0 ph. I know there is some amount of CO2 dissolved in the tap water that may lower ph. However, this would only raise ph after the filter churns the water for some time and some CO2 dissipates into the air.
What's happenning here? The difference is way too much between this tank and my old 10 gal with 7-7.1 ph
The only thing I can think of is something in the substrate. The first 2 bags were fine. The third one had the milky liquid instead of clear. I rinsed and drained as much of it as possible before adding it to the tank. There was still some cloudiness remaining which was taken care of by the filter overnight. Could this somehow alter the ph? What is that stuff anyway? I read a few threads regarding milky eco-complete, but didn't come to a conclusion yet.
I still have the other half of the bag left, so I'll test the liquid from it.
In the meantime, perhaps someone can explain this to me? Eco-complete wasn't supposed to alter ph, was it?
