Some rocks (could be the culprit).
4 HO T5 (2 10k, 1 colormax, 1 6,700).
Running a sterilizer too.
12 gold tetras
It's been up and running since Sunday mid-day... 3 days. Added fish on Monday night. They seem to be doing great... eating and looking very happy in a big tank.
However, pH is high... specifically how much? I don't know... test kit is blue. I added some buffer to it last night and it brought it down nicely... but it was back up this morning.
I know fish can survive in a wide pH range, but do I need to be concerned? What will a having a high pH do?
I don't want to remove the rock as I like the layout a lot. But.... should I? Or, can I live with it?
Thank you in advance for any guidance....
Take the rocks and pour a bit of distilled vinegar on them, if it fizzes ditch the rocks, if not keep them.
Trying to adjust the pH alone by chemical means with buffers, water softening pillows and such is a futile effort, a constant fight. Let the tank cycle and settle, this could take a while yours has only been up a few days, your tank is in a state of flux that hasn't even really started. It was 3 months before my pH started changing on its' own. So long as fish don't start dieing or showing signs of distress, things like swimming at only the surface of the water and looking like they are gasping for air, I wouldn't worry.
It can take several months for the tank to start lining out, I myself have had another member here remind me of this fact just a few days ago. To much to fast can and most likely will kill fish and keep you chasing your tail as it were trying to fix every thing that starts to go wrong, slow but steady, let the tank find its' groove naturally then tweak it here nudge it there to get it where it needs to be
Mean while read around, especially
the new tank threads that way when things do start happening (what's called new tank syndrom) that EVERY new tank goes through your ready, prepared, and can take it with a grain of salt and not freak out.
