I have 2 aquaclear 20s in the tank for filtration
I do a water change every week, about 50%, or whenever i see the nitrates creeping up.
I have the API master kit and have been testing the water every few days, the readings are typically 0 ammonia, 0 nitrite and the nitrate creeps up slowly over the course of the week.
The tank is fairly well planted, a few amazon swords and other leafy plants and i have a little cave in there as well.
I also have an bubble wall in the back of the tank for agitation.
I have done a water change and am changing the water whenever the nitrates get up to 10 ppm
The five guppies still in the tank seem to be doing fine, they play around all day and are eating regularly.
From what im seeing, I figure the deaths were most likely due to the bigger guppies picking on the little ones and just stressing them out. the ones left are all about the same size and seem to be getting along.
I am thinking about getting a few other fish for the tank in about a week, assuming the guppies are all still doing fine.
