Ha! I had well over 1500 ppm at one point in both my tanks...only discovered this when I got a TDS meter ... 1500+ that's almost considered brackish water territory... Surprisingly, fish and plants did well, but I don't think the situation would have been sustainable. The short story is that I only did 20% WC weekly at that time with occasional lapses and I had the remineralization dosing wrong for my pure RO water I did at that time (was paying too much attention to KH and pH in particular). I was essentially piling on to my TDS every week...@Geoffrey Rea is that 500TDS reading 'Total Dissolved Steroids'! WOW!
Cheers,
