That's one of those algae-preventer discs right?
This one is Shrimp model ,to prevent diseases, but i think it is the same thing.
Not sure how well they tolerate co2, but let me know how they fare. Know the estimated co2 ppm? Though I imagine it's pretty low because all that surface agitation from the sponge filters.
I have removed CO2 before... pH was 7.5, now without it is 8.3
That LCD thermometer is nice. Have you tested to see how accurate it is?
Yes, i have tested it - quite accurate. Good thing is that you can see the temp. from distance.
Does it use a wired probe that sits in the tank while the reading is stuck on the outside of the glass, or does it just detect through the glass?
It detect through the glass.
Gonna be keeping all the Sulawesi in the same tank? Don't recall which ones, but some Sulawesi prefer different params. Harlequins are smaller, but I don't think competition is worrysome as long as there is plenty of food.
Yes, 3 species in this tank. I think they will be ok with this parameters.
Looking at pics of Red Orchids vs White Orchids, I prefer the "more colorful" Red Orchids. Have you seen both in person? I haven't, so maybe the white orchids do look better (more "starry").
Never seen them in person. I can get Red orchids as well, but i decide to get white ones... For variation in colors (don't want all reds) :p
I have added some Marimo slices... Have to mention that this shrimps are not interested for food i am giving to them. Most of the time they are still hiding under the rocks.
