Is this normal?

yes exactly osmosis water has a sediment filter carbon and at the end resin to get zero tds when it's the weekend and I see that the tds reaches 180 160 approximately I do the change without adding anything

Hmm. RO water with TDS of 0 is essentially free of minerals like calcium, magnesium, and bicarbonate. It's not great for fish or bacteria.

yes but by changing the water I try to get to 100 120 tds maybe that's where I'm wrong? I don't put salts. sorry but now I have a huge doubt I have an oase 600 ok, sure I have the wool on top then the original blue sponge 😅😅😅how many matrix do I have under the bottom, damn I'm going stupid

The TDS is okay.....I would cut the RO 75% water with 25% tapwater and use a dechlorinator.
My TDS is 250ppm

ok forgive me nelson if I change 40 liters how much must it be of osmosis?😅

 

[max73]

I use Tetra Aquasafe but I remember that using it raised the TDS a lot, I don't know why

 

[max73]

so you say going back to the oase 600?

ok forgive me nelson if I change 40 liters how much must it be of osmosis?😅

30 Litres RO/10 litres Tapwater.

Fertilizers will also raise TDS!

Ok

 

[G H Nelson]

This is your best option to remove the cloudiness....if it bothers you?

ok I have to buy
