A couple of my aquarium have higher ec than expected and i'm trying to figure out why.
One of them has an ec of around 55 and ph around 6.8; i did an api test this morning and gh was around 3 and kh was below 1; i had presumed that if rock or substrate leached it would be kh and not gh; but what would raise the gh so high. This aquarium does have a different substrate - has been setup for around a year. I'll be taking some of the substrate out putting in a cup with ro water and waiting a week to see if the ec changes (though the plastic on the cup might also leach). This aquarium might have rocks i can't remember - it is a 65 and the fishes in it were said to like caves but it also has a lot of driftwood - mostly Mopani wood and a bit of spider wood.
The 2nd aquarium has the same substrate as a 20 long - it has an ec of around 50 while the 20 long has an ec of 18 (it has been setup for around 4 months while hte 20 long for a year). The only hardscape in this aquarium is mopani wood though it has a lot of leaves and plants - so again i'm not sure why the ec would be so high.
Thoughts/suggestion of what to look into ?
This is a picture of the 2nd aquarium since i have it handy - initially i was using it to test growing plants in blackwater but later added the a. ladisalo pair (female wants to spawn but male seem to snub her)
