All of my established tanks have a large established HOB nitrate filter hanging off the back. This is the first time I am hanging one off a sump facing the window of course. Amazing how sunlight out performs artificial lighting when it comes to plant growth. Below is a photo of my newly starting DIY nitrate filter hanging off the sump beneath my 210 tank. The photo is of the front and back with window light providing the glare. Note that I no longer use cartridge inserts but rather custom cut plastic craft canvas which give the roots something to attach to the plant takes hold, which also means no cleaning required, the plant roots do all the cleaning..
Below this today's photo of 1 of 6 established HOB nitrate filters that gets larger by the week with no help from me. Golden Pothos pulls the nitrates out so well that I cant see not having one on a fresh water tank anymore. Ill be doing additional water changes on my 210 tank until the plant gets established and large enough to start impact nitrate levels. About 1 to 2 months of growth.
