hi all..

i have started a 1.5ft tank for my tanga fish.. this is what i placed into the tank at the moment..

Coral sand with coral chop hidden under the sand bed..

the filter is a boyu ef-05 with biohome plus, cotton wood filter, active carbon..

is it enough to bring my water to the required?

which is:

Very hard water at PH 8.5 & above
KH & GH at 15 & above.

or do i still have to add stuff like marine salt? or other stuff? and how much do i add for a 1.5ft tank?

thanks..
