I have 2 pieces of driftwood in the tank, and the rocks are varried. I have 4 large pieces of rose quartz (looks really cool with my black substrate) one piece of granite and a few smaller black rocks that I don't know what they are.
My plants are mostly low to mid light varieties, a couple anubias, some crypts, a sword, some Java ferns, moneywart, and water wisteria. ooh, and I have one of those moss balls in there too (My son wanted it)
The reason I want to lower the pH is that it seems to be the thing that is most off in my tank. I have killed 4 otto's, 3 bristlenose plecos, a dozen neons and even a bunch of platys/mollies... None of them lasted longer than 2 weeks. I can't for the life of me figure out why. I acclimate them the way you are supposed to, I float them for ~20 minutes, add some of my tank water to theirs, wait another 20 minutes, add more of my water, wait another 20 minutes then net them out and into my tank. I don't want to kill any more fish, but I need a clean up crew to stay alive long enough to do their job.
The only fish I have that live happily are my 6 albino corys, 5 (out of 10) Serpae Tetras, one (lonely) Dalmation Molly and my male veiltail betta. They have all been in there for about 7 or 8 months, except the Serpae Tetras, they have been in for about a month.
If you know of any other reason I'm killing fish, please let me know.
