Apt Sky with high Tds

[babator]

Hello ...When I adjust 2.5gh water with apt sky..the recommended rate for me is 5 gr. Tds rate is 50 ppm.. the thing I wonder is why Apt sky keeps TDS high..

If you keep sensitive fish then a truly inert substrate and careful water parameters are important. I would not thought such fish would be suitable for a tank devoted to plant growth.

I originally bought them for my main tank, but after familiarising myself with them (there is hardly any info on them out there) in the quarantine tank (low tech), decided to dedicate this tank to them. Kept in 3 dGH, 0.3 dKH and 70 TDS they are doing fine and I have had them for well over a year now, the substrate is at least 4 years old.

I used to work with a guy that was slightly colour blind, he was a genius at getting the right shade of grey at the end point.

Yeah, it's a bit weird, mines not too bad, but those titration colour charts put it to the test.

Sorry @babator for the hijack, back on topic.

Active substrates last much longer in soft water, 4 years is impressive

Active substrates

Always fought shy of Active Substrates, probably lazy, could not face a strip down.

Very nice tank and happy healthy fish. I had to look them up on the internet.
