Water Parameters

[chappyeben]

Just did a water test with below parameters. Any advice/recommendations please?

NO3 = 25
PO4 = 0.03
KH = 11.5
CA = 450
MG = 1110
Salinity 1025

I'd do a water change. dKH is high and Mg is quite low. I think try do a water change and then test again.

First check what the dkh is of the new water. No point in doing a waterchange if your new water also has a dkh of 11.
I will just keep the parameters as is and maybe lift mg to about 1350ppm. Kh will come down on its own eventually.

Any "household chemicals" I would be able to abtain at pnp now to raise the mg?

Have a read here.

Can I use Epsom salt alone to raise the mg?

If you are going to do alot of WC's, run your parameters so close as possible to your SALT's lableled parameter.. That way you do not get small swings when doing a 10-20% water change every time

in theory you can but its not the right way of doing it.

I understand, I just need the best way to raise it now. What are the other preferred option, water change?

Personally i use Red Sea Reef Foundation C

Thank you. Not sure if that is available now with the lockdown.

Thank you. Not sure if that is available now with the lockdown.

As some of these items are vital to keeping livestock alive, some LFS have got permission to sell locally. I spoke with a LFS in Durban and he is allowed to operate and sell necessities under his lockdown permit, but may not do deliveries out of the metro. Maybe phone around locally and see who can supply you with what you need.
