hi bros and sis. i just got a bag of used sand. the thing is im intending to use it for a low tech tank. However, the sand was previously mixed with base fert.. im using only moss for the scape. will the base fert affect my tank water in terms of its nutrient? i dont want my tank to get algae bloom..

you can go ahead and use it, just have a 1cm layer on top of it. You should be fine.
Cheers, Christophe
