I've been watching the thread about Corydoras performance on sand versus gravel. https://www.fishlore.com/aquariumfishforum/threads/busting-the-sand-cory-barbel-myth.273423/ I got a lot of information from that thread. Busting The Sand Cory Barbel Myth. I've also not sustained consistent plant growth and I am considering removing all the local river gravel sand combination used since I started this tank a year ago and adding soil beneath a layer of sand so our Pepper Corys might have an easier time working the substrate for food.
Also have a new Java Moss coming.
Water tests today. pH 7 hr-pH 7.6 ammonia 0ppm nitrie 0ppm nitrate 20ppm temperature 74F
30% water exchange glass cleaning vacuum general tank maintenance
I also removed most of the inch size gravel leaving local river sand trimmed plants.
What type of soil should I use?
what would be a good quantity of soil to add to a 48 inch by 12 inch footprint tank.
I'm certain there a many things I haven't considered. Please let me know what is important.
