My grandma gave me one of her freshwater tanks, fish and all. I've never had one before and am in need of some good advice.
Here is some history and specs/parameters...
1 angel fish
5 redeye tetras
Some plants, not sure what they are, so I uploaded video footage of it all on YouTube...
My grandma ran it without any pumps, letting the plants handle all the conversions. She fed the fish quite often and vacuumed the gravel once a week. Not sure how often she did 1/3rd water changes.
The guy delivering the tank ran and got me some pumps/filter to add.
He installed the MarineLand Pro Series Bio-Wheel Power Filter Emperor 280 GPH, "for up to 50 gallon aquariums" (not sure how they come up with that number), which seems like major overkill, if you ask me, especially when you consider that it's cycling my entire tank's volume (about 38 gallons), over 7.3 times per hour, but I'm running it as such for now.
There's an APp4 AirPod pump and an airstone...
Hexagon shaped, 11.5" side pane width X 24" bottom to top of water, with 2.5" of gravel displacement, I figured around 37 or 38 gallons.
Temp appears to be 80 - 82 F.
pH appears to be between 8.2 - 8.4.
Nitrite is at the bottom of the scale.
Nitrate is between 20 - 40 ppm.
Ammonia is .25 ppm.
2.5 gallons of spring bottled water were added around 36 hours before I took the waterchem tests.
My main concern at this point is the pH. I should try to bring it down, right? How much how fast?
