about 3 wks ago i added a tennis ball size pc of LR to the wet/dry sump area with the idea this might help with water quality issues. now i am starting to see green algae. could that small pc be changing the base rock in the DT into LR and how would i know for sure or is this an algae issue i need to get in front of. algae is also showing on inert real coral pcs.
