Best practices for introducing to a CO2 tank
This is for neos going into a high tech tank. How long should this take?

Turn the CO2 off for a day.

Let them acclimate to the tank over night.

Then slowly add CO2 back.

Would the start of a 72 hour blackout coinciding with that first day of no CO2 stress them, do you think? I'd add some algae wafers for them to track down.

sounds like bad idea about to get worse... good luck

Why the blackout?

If something is wonky with your tank, you should probably get things in check before the consideration of adding shrimp.

It's to clean up the aftermath of a CO2 deficiency. There's still brown scum on the glass that I can't clean without disturbing the substrate and affecting the current population of ghosts and amanos. There's also brown dust on the MU (or whatever it's called this month), which is inaccessible without removing the entire hedge.

Got photos?

May help us come up with ideas to help.

I'll post some tonight, thanks.

Doesn't look blackout worthy.

Just need to get your lighting, ferts and CO2 in check.

The first photo looks like cyanobacteria but I can't tell from the image.

Here's another shot.

I think I have it all roughly in balance again. Had to replace old bulbs just after thinning out the floater cover and the CO2 wasn't up to the load. I've since replaced the lily pipe for a spray bar angled to maximize O2 - I now have individual surface boils for each jet. The CO2 level has been increased to just below signs of stress in the inhabitants.

The dust in the second picture makes me worry that there isn't enough flow in that area, so I'm considering a nano koralia, though I detest the idea of adding anything else to the tank. It's only a 29g.

Ferts are EI but with frequent testing to keep NO3 at 10-20 ppm. At the time of the outbreak I discovered the test strips had been wildly inaccurate: NO3 was actually 80-160 and PO4 was 10+. I've had a roller coaster ride getting them to acceptable levels but it seems okay now.
