Lights ✅.

Two AI Prime 16s.

Install involved borrowing hammer drill from the neighbors to bore into concrete ceiling, fun stuff. Then when I was testing the lights I set one down on the velvet couch not realizing it was on and burnt a series of small holes 😭. Not exactly a smooth process but everything is up and working.

I’m nervous about algae so I’ll be running the lights at low output for 8h a day, scaling things up in the coming weeks. The rock has been in salt water since 26th of December and with fish for over 2 months so I’m confident the initial cycle is complete. Last test 1ppm Nitrate. Cheto in the sump is growing like crazy so levels should stay down. But still, algae will come. Hope the foxface eats most of it.

Been enjoying C++ lately working on few Arduino projects. Now want to try and make a simple text based rouge like with raylib. https://www.raylib.com

Months ago I built a simple roll a ball in unity game. With help of tutorial made free because of pandemic, good move unity. Had this concept for a series of games “5min of fun”. Small games to help learn game programming and challenge myself outside web app I’m always programming at work. Looking to add to that series.

The reef will soon have light! Ordered two AI Prime 16s with ceiling mounting kits. 💶💶 My bank account hurts but looking forward to first coral soon after.

Hiked all around Kofel Sunday looking for the start of a multi-pitch. https://www.bergsteigen.com/touren/klettern/linke-achsel-kofelturm-kofel/. Finally found it on our way back down. Looking forward to trying it next time weather is decent.

Don’t really need comments on my personal site but if I did this federated solution looks cool. https://cactus.chat/

Major progress on my life clock project. Managed to load 17 years worth of adjectives onto the micro controller.

More on the project after I finished. Documenting progress in a dev log I’ll turn into a blog post then.

After more pondering I’ve decided it was the crappy Sera brand heater. It was not heating very well so I cranked it up to max to try and hold near 27-28. I think in the night it managed to hear all the way up to 32 🥵. Already replaced it.

Not sure if I’ll go for another Scopas tang at this point.

#reeftank

Unfortunately the Scopas has died. Still figuring out the exact cause. I raised the temperature slowly to 27.5 in order to speed up the ick cycle but other then that no changes, good salinity, no ammonia, little nitrates, decent dkh and ph, enough food.. 🙁

Not sure if I'll try again with another tang right away. Either way I'm going to run the QT tank for a 1.5 weeks at 28 deg with just the cleaner shrimp and snails to git rid of the ick.

Fun to come back to python's functional programming docs, https://docs.python.org/3/howto/functional.html I had forgot about list comprehension.

@tomdeb I have not. Looks nice. Its architecture page it’s pretty impressive. I think the difference is my setup spins up a real chrome instance for the scraping where I think I this makes the web request directly with python.

If I have a use case that’s does not need JS in the browser to fully render stuff I think I’ll reach for scrapey thanks for the tip.

Excited to try out new micro controller, Adafruit M0 Express Feather.

Hmm flashing is not working...

30min later wtf..

USB cable I was using was charge only and does not support data transfer. 🤯

Been web scraping for one of my personal projects. Years ago I used python + beautifulsoup which basically curls the page. This time I’m using python + webdriver. Wow is it nice. Can even scrape client side js rendered pages!

Scopas tang has ich. 😔. This is why we have quarantine routine. No other fish affected. I’ll start treatment this week with Cupramine if I can find here in DE.

Not sure what to do with the skunk cleaner shrimp and 4 snails 🐌🦐 that are currently in the quarantine tank. Apparently raising temp to 28-29 for a week in tank with no fish will take care of ich traces. So I guess I’ll treat the scopas in a bucket 🪣... not sure yet.

My new scopas tang(brown tang) and scarlet skunk cleaner shrimp interacting minutes after entering QT tank.

This was my first time receiving a live fish shipment. So far so good. The poor guy is pretty skinny (common wholesaler practice to minimize ammonia in shipping process). I hope he will eat in the coming days and put on weight. Got the nori and frozen food ready.

Why scopas? At my current display tank size many tangs will outgrow it quickly. Options were yellow tang(250€+ here in DE), bristletooth tangs like yellow eyed kohl tang which are beautiful and fairly priced. Or since I already have yellow fox face but still wanted Zebrasoma, Scopas! So what if he is brown. Still looks cool and will keep algae at bay.

#reeftank

My three blue green chromis finished quarantine yesterday and joined the display tank. Fish 3-5. They are very active swimmers staying in upper 1/4th of the tank.

Finally hit zero nitrite! The tank seems to be cycled. That or the cheato in the sump is effecting it. Probably should have waited for cycle to complete before setting up refugium.

Nitrate is 1ppm or under and 0 phosphate. On track to buy and turn on lights next month.

Some cool zsh tricks.

I never knew of the take command or parking commands. The article also inspired me to write a small utility to search duckduckgo from the command line.

Starting to get some algae growing on the rocks next to the refugium chamber in my sump. I think I need to add some sort of hood / dividers.

I’ll blog about the cheto and the refugium when it starts working. Right now half of it died off, which I removed, and nitrite levels are still high. Basic setup is: Kessel H80 LED and some cheto I bought online from reef shop here in Germany.
