I'm a student in the DC metro area and I'm taking my old tank I was given as a kid out of retirement, this time hopefully as a beginning hobbyist instead of little girl who wanted an "easy" pet! My tank is a 15 hex, and I know the shape is not optimal, but I'm trying to make it the best I can nonetheless. Hopefully the rest of my post isn't too long for the introduction forum!

I've been reading about freshwater startup and maintenance for months, and I'm currently in the midst of cycling, using the fishless method. I'm three weeks in, and my tank is in its nitrite spike, while ammonia is finally steady at 0ppm. If all goes well, only a few more weeks before I can start to add fish!

I want to keep mainly tetras and other fish that would live in the blackwater environment home to tetras in the wild. I'm currently messing with my water chemistry to achieve very soft, acidic water found in that habitat. It's very difficult, however, because DC water is notoriously bad and very, very hard! GH was off the scale of my test strips before I began conditioning, and pH was above 8. I have replaced about 30% of my water with distilled water, which brought pH between 6.8-7.2 after letting it mix for a few days (it's hard to tell exact numbers with the test strips), but GH only down to about 150ppm. I'm hesitant to add more, because my KH is getting low (40ppm) and I really want my water to be stable.

I have ordered some driftwood, and I've been considering peat moss as well. I'm assuming that many of my questions will be in the area of water softening and peat filtration! I'm probably going to introduce my drift wood this week, test parameters, and if things are going well (and the wood is sinking, of course) pick up my first live plants next weekend.

Sorry for the long post; I'm just really excited about starting up my tank (if you hadn't realized that by now!) but everyone I know just laughs when I start talking about the aquarium. I'm excited to have a place where I can ask questions and not be laughed at :)

:hi:Hi, onebyone. :welcome: to AC. You'll find lots of people here eager to help you. I'm relatively new to the hobby myself, but I think many will agree with me that you need to finish your cycle first before you start trying to mess with the pH and water hardness. Also, I think many will advise that it's not advisable to mess with pH and hardness in any event, unless you have a degree in chemistry, and even then you should probably just leave it alone. Lots of fish will adjust to pH, given time to acclimate. As for hardness, well, I have the type of water you're wanting, except mine tends to be way soft. Everytime I try to raise the GH and KH, even just a little, it seems one of my fish doesn't do well. So, I've just come to accept the water as it is and leave it alone. Good luck with your cycling.
 
Thank you! I never knew that it was best to wait until after cycling to change water chemistry. I will just stop messing with it then and see what it looks like in a few weeks. I probably will not change it all that much past what I've already done if it stays steady, but the parameters were just truly awful with tap water. (I am studying chemistry actually, and I've been having some fun with this testing out buffering capacities outside of the lab setting. I definitely am not an expert, though, and I don't want to hurt anything too badly).
 
Welcome to AC! Keep dosing ammonia....
