Durban tap water

Hi guys

I am new to this and have been reading through all the valuable information on this forum. I want to set up a 3ft planted tank using pfp as a substrate. I however do not know anything about the water in Durban except for what i have read up on this forum. Are there any ins and outs that i should be careful about ? I may add that i did not pick up any hardware as yet, I have been scouting the local lfs for deals but that just confused me even more.

So far from reading

i will need
1x 3ft tank
1x stand (sturdy)
canopy
pump and filter with media
substrate
lighting

any recommendations will be highly appreciated, especially with the type of pump i will need. I am caught between hob and internal canister pump.

regards
