First, some good news.
I added my first piece of coral yesterday! A happy little GSP frag. As basic as it may be, it’s super exciting. We’ll get around to the nicer stuff once I’ve proved I can keep things alive.
Now for the bad news. It’s time to face my first adversary. Dinos are here, and they’re here in force.
Tuesday afternoon after a day of light!!!
Thursday morning after a short blackout.
This behaviour, combined with the pearling and stringy structure, leads me to believe it's Dinos and it's releasing into the water column at night.
I’m not entirely sure why, but I suspect the cause could be high TDS supermarket RO water and too much light. My LFS is a bit of a drive away, so over the past couple of weeks I’ve resorted to using supermarket RO for top-off. It was cheap and readily available. I took a sample to the LFS yesterday and asked them to test it. Turns out the TDS is around 130–140 ppm. YIKES.
Based on other people’s experiences, it seems a full arsenal works better than any single weapon. Here’s the strategy.
Please chime in if you have any other recommendations. I’m all ears. The one thing I can’t really do right now is UV, as a proper setup is cost-prohibitive.
- I’ve cranked up the flow as much as I can with my single small powerhead.
- I’ve reduced the lighting intensity and shortened the duration by a couple of hours. If that’s not enough, I’ll dial it back further before trying a multi-day blackout.
- I’ve seen a bunch of people recommend stopping water changes, but I don’t really like that idea. Instead, I’ve picked up some Seachem Reef Nitrogen and Aquavitro Seed to keep bacteria growth and nutrients up while doing regular water changes with decent RO water. I’ll siphon out any new dino growth as I go.
My phosphate has been pretty high for a couple of weeks, so the plan is to bring it down with water changes while dosing nitrate to try to get the two in balance.
- I’ve also ordered a live pod culture.
In other news!
The Home Assistant smart reef gets better by the day. I recently picked up a little temperature and humidity sensor and an IR blaster so I can turn my dumb aircon on and off while I’m away. Hopefully that’ll help keep the tank temperature more stable. South Africa is pretty temperate, and central heating and cooling systems aren’t all that common unless you’re a baller, so this is the next best thing.
Next up - a leak sensor for under the cabinet and a smart plug for the skimmer so I can set up water change and feed modes.
