So, I've been researching for weeks regarding the best route to go as far as refugium substrates (which is the best) or no substrate at all. To be honest, I haven't got a clue??? Everyone seems to have different opinions and I'm looking to gather the opinions from this thread and formulate a plan for my 75g build. I want to know what sand (fine, course, DSB
, etc), Refugium "product" or if you just have nothing at all. They all seem to have benefits...
Alright, what substrate, if any, do you use in your fuge?
