Well, I discovered something new this week. Maybe it shouldn't be new because it's probably a principal of biology. I think many times we forget (at least I do) that our living organism inside our glass boxes breathe. As part of respiration, I assume, this is a source of CO2 that brings down PH. However, I never assumed that my living organisms would have much of an impact, if at all.
My PH is hitting 8.1 a number I've not seen since 3 years ago. Back then I was hitting close to 8.4 daily. Pre-vodka dosing, pre- denitrification systems in place, and pre-large fish.
In the last 2-3 years my ph tanked to 7.5. I stopped vodka dosing and it came up to 7.7 at night and around 7.8 during the day. I moved my Skimmer intake hose to near outside my house to pull in fresher air, and it ph went from 7.7 at night to 7.88 and during the day around 8.00 if I got lucky.
This past week I removed 2 Creole Anthia Fish from my display. The male just got too agressive for my community tank and I found a taker for a predator tank. So, I gave the male and female away. The male when caught was 12-13" in length, the female is around 7-8 inches in length.
I noticed my ph climbing to over 8.1 since removing the two fish.
I don't know if fish resperation would that greatly impact PH. I've got other larger tangs too, am wondering if I need to go all small fish now. heh.
