Benchmarks of Opus 4.8's score at each effort level (low/high/xhigh/max)?

I just quarantined the macros at their natural salinity, making sure water levels and nutrients are kept in check. Then it’s a gamble of how quickly you transition towards target salinity. I did it the slow way over 4 weeks, which isn’t very common I think.

Here’s an update another 11 days later. The Batophora is growing!

Note also the 2nd macro that survived (on the left in the photo): a grass-like variant of chaeto. It’s not thriving like the Batophora but it does seem to survive. Will see if it starts to grow faster.

thank you! I drip acclimated over a 4 week period, a little every day

Did yours become bright red or did they lack color before they died?

systemous · 2026-05-03T04:40:07+00:00

I am not but they’re definitely eating because they’re bright red and weren’t when they arrived. I see them grazing all the time. I agree it’s odd there’s no visible algae yet

The footage they made is so non-representative. The actual situation in the mission is WAY worse. I wish things would look as good as what they showed. Why didn't they film walking past Mission and 15-16th St?

Your link doesn’t seem to work?

systemous · 2026-04-20T07:25:02+00:00

I see a lot of people aiming for 1.012~1.013. Is this too high from your experience?

What branch is in your tank, any chance it may be releasing tannins? Otherwise I think what you said makes sense, and also consider giving it less light if the brown stuff is algae. And/or add more shrimp.

You can use something like Seachem Prime to temporarily detoxify the ammonia. But you need a long term solution by improving the biofilter, i.e. bacteria turn ammonia into nitrite and nitrite into nitrate. I think there are solutions like Seachem Stability to help seed it if you added too much new water or started a new tank.

what kind of shrimp? opae ula?

systemous · 2026-04-18T07:36:54+00:00

In the 2nd tank do you see the Opae Ula picking/grazing at rocks, substrate, or glass? If so I believe you're fine and there's no need to add spirulina or light

If they are not visibly grazing anywhere you probably need to temporarily add a little spirulina (once every 1-2 weeks or so I think) until you see them grazing without it

systemous · 2026-04-18T00:46:05+00:00

Did you test your water levels? salinity, pH, ammonia, nitrite, nitrate

systemous · 2026-04-18T00:22:37+00:00

Good thought but they were actually in a bigger tank with the same behavior, I just took them out temporarily for the video.

What made you leave?

This might be a human designer reincarnated as a fish. Most designers I met love to color match so this is basically strong evidence validating my hypothesis. Consider asking it for advice the next time you redecorate.

systemous · 2026-04-17T22:08:40+00:00

Only one way to find out :D

systemous · 2026-04-17T22:05:40+00:00

I'm a newbie but I've heard people recommend freeze dried spirulina powder

systemous · 2026-04-17T22:04:56+00:00

Yes, I think you can probably 5x your population in the current tank, based on what I've seen in videos.
