Here’s a photo of the tank. All fake plants now.
If you want to lower nitrates you're going to need lots of fast growing plants. Anubias and java fern are very easy but won't do much for nitrates.
Water changes are the best way to lower nitrates. If you have high nitrates in your tap water (like me) then using Seachem Matrix in your filter is more reliable and effective than live plants imo.
