Besides the drop checker a standard way to measure is the ph drop. So you want to take some tank water and let it degas for a day or so and test the ph. Then test your ph with the co2 running for a few hours into the cycle. Generally your looking for a 1.0 drop. So if your degassed ph is 7.5, your aim should be 6.5. This usually indicates approx. 30 ppm and is a good amount for plants and fish in most setups.
As far as fish, that's really a personal thing. I usually go with what's available locally so I went with Embers. They have been extremely hardy. I haven't lost any since I started the tank, but you have to like orange. I think in most scapes one big school looks better than a variety of fish. I also have some Black Neons, which I really like, but they are actually too big for my tank scale wise.
Hi, right that's what I should double check to help me feel more confident - anyway I ordered a PH test kit.
I decided to order some ADA soft water as well and give that a try, wonder if it works!
Indeed it is, yeah you're right keeping it more simple without tons of different fish is best.
Tank looks great! Definitely following progress. When I recently installed my co2 kit it was recommended different working pressure depending on your diffuser, where the inline was rated the highest (I have that too).
Check your manual, I beleive for co2arts they recommended at least 30 psi for inline diffusion.
Thanks a lot! Thankfully my regulator is a nice double chambered one with adjustable working pressure so I might continue to play around but I understand right at about 2 bar (~30psi) is where I should be with this diffusor. The only thing confusing me is that the bubbles from my bubble counter seem SO much slower now but also a lot bigger I would say.
As for stocking I think I had a break through last night... haha, very big decision
I think I will go for a ~15 group of Green Neons - I think the slightly smaller size and blue/green stripe should look cool with the darkness of the lava rocks and so on.
I still can't decide about the other fish for the bottom side of the tank.
Right now I am thinking about the following options:
-A small group of Dario Dario (ideally 3 females, 2 males?)
-A small group of a Pygmy Sunfish sort (likely elassoma okefenokee? likely the same kind of group size like Dario Dario)
-A pair of Apistogrammas (not so into it because I find they are all probably too big for scale here)
-6 to 8 or so of the Cory Habrosus
Besides that maybe eventually a few Otos... not sure yet, probably those later on.
Also with my stocking plans I can go with shrimps so I will definitely being getting amanos, and possibly a type of Neocaridinas.
I will be ordering this weekend, the online shops start shipping on Monday, no use ordering now as they only ship live fish Monday-Thursday here - so I have a bit of extra time to think it over. Also Dario-Dario and Pygmy Sunfish are sometime able to be found locally from hobby breeders, as well as Apistos - so I can consider that for them at least!
