Hello All

I have attached my local water report, Swakopmund Namibia, Some of it is still greek to me but the Tds looks very high as well as chloride, calcium, CaCo3. Which should i be concerned about and what can i do about it.

Advice very welcome.

I am building a diy filter to connect to my tap line,

pvc tube with tap fittings filled with layers of
floss, peat moss, fine sand, carbon and sponge. (any other suggestions)
This will save me a lot of work transporting 100liters every week.

Sorry , copy and paste it will be then

for your fish I would be most concerned about the chloride and nitrite.

Treating your water with a de-chlorination product when water changing will take care of the chloride

the Nitrites will be taken care of with a properly cycled aquarium.

The nitrites for the most part will be more problematic regarding algae in the tank, unless you plan on planting your tank......
 
TDS is very high.
Na (sodium) at 215mg per liter is very high. That is almost saltwater.

The Nitrite is very low, and OK in an exstablished tank.
 
Puffers would love that hardness...so would a lot of cichlids (but not in the same tank!).

No it won't. Chlorine and Chloride are quite different chemically and do not undergo the same reactions. It's only an electron difference, but it completely changes the chemical properties of the atom. For starters, chlorine is highly toxic whereas the chloride ion is not.
 
It's odd to me that things are marked either good or excellent, there is no other designation. I don't think any contaminant, no matter how small, should ever be considered excellent in tap water. Is this lab legitimate, or run by your water company?
 
Thanks i figured the water here was a bit out of wack, this test is done by the water company, the excelent and good is just the rating given to the water as drinking water. A - excelent, B - good etc. However, the water tasts crap.

I use filtered water which helps with most of the tds. I cant attach the print out as it was sent to me in pdf.

Filtration doesn't reduce TDS - it's total dissolved solids; filtration can only remove suspended solids.
