Rooting Quality of the Substrate
I have a handful of questions that I have not been able find answers for during my study, I have posted them below. Thank you in advance for helping a fellow aquatic plant enthusiast! I used potting soil topped with black diamond blasting sand in my 75g. My larger plants whose roots grow deep into the soil absolutely love it! The problem I am having, is with my smaller specimen whose root systems expand horizontally (DHG and s. repens). The sand seems to be too dense to allow the roots to grow normally, it also inhibits the emergence of new grasses, (DHG and tall hair-grass). My sand cap over the soil is as much as 2.5 inches thick in some areas. I will be moving across the country in the next year and I am planning to downsize to a 10g and I want to ensure that I perfect my substrate for carpeting plants.
Can/should I use a thinner layer of sand? Maybe 1 inch or less?
What do you use for s. repens?
How do you deal with tannin from the soil? My water turns a dingy yellow as few as two days after a 50% to 100% water change.
Does anubias prefer to be grown in or out of the soil? What light conditions are best for it?
I have submitted a photo below, please let me know if it cannot be viewed or it does meet the forum requirements!
pH 8.5, acceptable levels of nitrates & nitrites
