African cichlid newbie tank stocking questions

[Linz244]

I'm no monster keeper yet... I'm young don't have a lot of money but I wish to be one!!Hey there, I'm new to the forum so I really dont know how this works. But I do have some questions about cichlids. I have a established tank that used to have community fish but now I want to change it to dwarf cichlids.I was looking at the juli and the Lamprologus Calvus, but mainly the juli. So here are my question, there is a lot!

1)How many juli can I put in this tank?( not intended to be breeding)
(Golden Julie, ornate Julie, yellow Julie, Daffodil brichardi, and masked and plaid Julie)
2)I still have gravel from the community fish tank, should I change it to sand?
3)Also can other types of small cichlids be put with the juli, if so what kind?(keyhole,Lamprologus Calvus, maybe Altolamprologus Compressiceps)
4)And the last one how do I raise my ph?( I have herd of crushed coral, limestone, buffers, proper ph) my ph is from the tap is 7.5

Thank you so much for your help and cant wait to see some replys,
Lindsey

What size is your tank?? I would suggest coral sand as means to raise and buffer your pH, but there are also many different chemicals you can use to raise your pH.

The amount of fish depends on the size of the tank. I used crushed coral substrate to buffer the ph.
