I've got a sprayer bar on my canister filter's outlet, but it sits about three inches below the surface and even though I have the output angled upwards, it isn't agitating the water as much as I'd like. It used to, but I increased the water level since starting this tank. It is a planted tank with the usual culprits like anubias, anakaris, jade, jade moss and a large sword plant. The fish are a variety of neons, a variety of plecos, and three dwarf gouramis. It is a 70-75 gallon tank. I currently have an airstone going, but I really don't consider that ideal and I consider it a temp fix. So finally my question is should I consider a wavemaker for surface agitation? It seems the jury is out on having one in a planted tank and also what hours it should be run if used. Would love some good advice 🙂
