I sense that DSM may be a case to case basis, from what I understand at least.
Substrate is Fe rich soil mixed with river sand. I'm avoiding the term 'laterite' because I'm pretty sure it's not just laterite.
I know Glosso works well with DSM , but can you grow hygrophilia polysperma emersed as well?
I read somewhere that once you flood it, you should lower the intensity of the lights? I'm running mine low to medium level, should i bump it up when DSM'ing?
Here's a link to the tank, just in case. =b
