Any idea if can just use coral chips and baking soda? Or need to add salt. |
baking soda is to bring up the pH to about 8-9. which is good enough.some dont even bother about pH.
as for stabilising the pH, some use epsom, some use marine salt, some use coral chips, some dont use anything..
read up more on the water chemistry and come up with a mixture and routine that suits your fishkeeping style the best.
different people keep different fish, different tank setups and different water supply.
filtration wise if i would suggest, then just load the IOS with biomedia and use the OHF for mechanical filtration, should be enough. more layers and you can add biomedia on the OHF too.
