you might keep an eye on your nitrate concentration if you haven't tested it. Reduced pressure can occur as the CO2 is depleted. I DIY CO2 and notice this.

How did you calculate 17:7? Is that 17 hours on and 7 hours off? Just asking because I'm a bit confused and trying to figure out my photoperiod as well. I counted 11 hours on and 13 hours off. I thought that was okay.

I'm assuming his home isn't pitch dark between 10 am and 4:30 pm, so his fish are subject to light for 17 hours and dark for 7 hours.

If it is pitch dark between 10 am and 4:30 pm, then he is subjecting his fish to a 5:6.5:5.5:7 photoperiod, which is probably more stressful than 17:7.

Ah, ok! Thanks. I didn't think of that. I run my light when I get home so I'm on the same boat. I have to cut back or light it up earlier!
