125L - The Re-Scape

[Tankless]

How's the growth been with the Tropica ferts?

Hi all,

So question - I've just checked and my water in the tank is at 496ppm. Does this maybe explain issues of growing some of the plants? Is there a way to remedy this, or do I need to just get RO water?

I've heard 120ppm is the best.

The ppm TDS value is a measure of the salts in solution and if you have hard water most of those ions will be Ca++ & HCO3- ions from dissolved limestone.

A lot of people will have similar water and successful tanks. There isn’t any easy way to remove hardness, which is why some people use RO.

If you don’t use RO (or rain-water) you can look at rise in TDS and just change enough water to keep it within a datum range.

Cheers Darrel

I'll link a few threads in. This Jordi @parotet <"talking about his water">. These are @akwascape's <"low tech hard water tanks"> and this is @Zeus. <"Olympus is calling...">.
