Hi @Jscholtz014 if you can, reduce lighting period and stay away from reds and oranges if you running led. You want to also drop nutrient levels nitrate/phosphate and scrub rock in a bucket of tank water. Also I normally don't rush an algae eradication as the tank should be allowed to gro through with it's natural cycle to some extent because as the saying goes in this hobby it' only bad things that happen fast :). Cheers.
 
Hi there:001_cool: @jclaas.
I will reduce lighting schedsch to 6hrs per day..

I recently replaced all my sand.. So I have a sneaks suspicion that it could be the bacteria removed that has now caused a mini cycle.. Could i be correct in saying this? Regards
 
That's plausible and it makes sense. Everything shold stabilise again :).
