I'm not the best at aquascaping (I'm horrible actually) so I know the design will be critized by some. Anyway here are the pics. I will have some readings from the testing later today. I just added the fish yesterday, and the plants a couple days ago after waiting for my plant order to come in. I used Bio Spira with it and I am hoping I didn't get a bunk batch because then I'd have to probably take the fish out and do a fishless cycle or try another batch.

Some tests today since adding plants 2 days ago and fish a day ago (one Otto died I was hoping to avoid this happening since I've heard it happens to Otto's commonly...and one I can't find, but he's probably just chilling behind a wrong somewhere).

Ammonia-0
Nitrite-0
Nitrate-0?? I'm guessing nothing has even happened with the water yet and the nitrate from the tap water has been filtered out by my plants
Hardness-75 ppm
Alklaniity-80 ppm
PH-6.8 It was at 7.5 a day ago and my CO2 hadn't started up completely, so I'm going to be watching this to make sure it doesn't drop even more. What can I do to bring my PH up if it goes down more?

ottos actually die frequently out of a group anly a few may live. So I've heard and experienced.
