It grows well but i have no way to compare it to others;most of it has been trimmed a few times long the way.
I think steady alk, sg, ph and lighting play a role. Food too via fish feedings and bacterial growth feeding other fuana and of course low PO4 and NO3 and good skimingand gac to help manage organic levels.. No issues (stn, etc) for over 3 years cetainly helps .
I don't dose any trace elemets, amminos or minor elements like potassium ,iodine stontium but routine water changes add some of these as does the feeding.
