So I am starting my 28 gallon bow front build. When I took it out of storage I new it had a leak so i stripped off all the old silicone and I will reseal it tomorrow, I am using GE 1* clear silicone for windows and doors. I am going to put african cichlids (yellow labs) in it. Also the live plants I will use are going to be java moss, java fern and anacharis. I am going to use play sand as my substrate. I am also going to make a diy stand/canopy for it. I have a few questions.
1. Should I put organic potting soil under my play sand?
2. I have heard that the soil makes the water acidic and that some fish don't like acidic water, do yellow labs like it?
3. Should I put in limestone because it raises ph, I hear that african cichlids like high ph.
4. To help jump start my cycling should I ask for some water/gravel from my petstore or do you think it has diseases (pj's pets)
Thanks
Here are some pictures
