do share photos of how you positioned your spray bar so that others can learn.i fixed it, the spray bar was at 2.5cm but i think the flow was too high and the surface agitation was insane, so i placed the bar 3.5-5cm from the top so less surface agitation, the levels are now perfect, no more BBA, tons of bubbles, insane new growth, no stunted plant anymore, even the cabomba furcata make new pink leaves. No more algae on the glass =)
expert on this forum were right, CO2 is the key
