pH swing------7.7 to 8.2

[onthefly]

So what's a 5.5 guy supposed to do without a fuge?

 

pH earlier today was 8.2.....after lights off for a 30 min its 7.7.

 

I have a little halimeda for macro...that's it!

 

Parameters:

 

Amm 0

NO2 0

NO3 0

PO4 0

pH 7.7 (now at 9:30pm)

KH 8.0 (a little low)

Alk 2.96

 

Assuming this is a CO2 release from my algae.....what can I do without a fuge? More buffer?

 

Thanks,

Sounds fairly normal to me, I would just leave it alone.

Do you dose B-ionic? if so try it after the lights go out and see what the ph does.

Yup...that's a fairly normal pH swing. The alk/kh could be a but higher. I'd also check my magnesium level. Otherwise everything seems cool.

Bueno!

 

I added some buffer last night...to bring up the Alk

 

I dose with seachem reef complete (has Mg in it).....Ca bounces between 400 and 440

 

Thanks for your help!

 

Damn Physh! are you a farmer.....why the hell you up at 5am!
