Hey everyone I brought a fluval evo setup from my friend it’s been running for almost a year and I haven’t touched a thing since just weekly maintenance the problem I have is I’m still getting diatoms and I’ve recently found out that the sand is silica sand and ocean rock that came with the aquarium could be causing the issue from them releasing silicates still. I was wondering if it would cause a big problem if I do a total rescape on the aquarium if it would affect the livestock if I keep them in the aquarium while I change out the rock and sand
