Res change day !
I went with 30% lighter nutes this time, and no more Golden Tree.
Still added tea.
I also pondered hosing off the roots too, as it knocks off some smaller brown roots and clogs the top blue screen.
I opted NOT to, and simply cleaned the lower res, pump etc, and refilled, and still more stuff floating, circulating around just from the draining/refilling.
Well, I took off that top blue screen and added a filtration system down at the return into the lower res.
I didn't get a pic, but I set an extra net pot on top of the drain tube and it keeps good roots from swimming/floating with the flow down the drain, while letting the small loose pieces thru to the filter.
Opened the hole up a little in the lid and attached a piece of a knee high nylon stocking to a spare plastic sink drain piece with a rubber band.
Now I can shut of the pump and remove the filter, backwash it with the hose and be back running in minutes.
Overall, the roots look really good and Plentiful.
(you can also see I added a small Damp Rid (fragrance free) moisture extractor in the back, we have had some hot sticky weather lately.)
