Algae problems, Cyano or Diatoms?

[GoFish]

Does anyone else think that really coarse substrate like that could cause issues by trapping detritus and pockets of stagnant water? I would think the water quality at the bottom of the tank could contribute to algae.
Just a thought

yes absolutely , while ditrius its self is near the end of the line , trapped foods def will break down into nitrogen and phosphorus which can fuel cyano for sure

i personally wouldn't have such a large grain sand bed either
