No algae problems like I used too. Less light, less dosing. Switched to DIY root tabs from eBay and use Algae Fix every few weeks when things start going sliding down hill. Usually due to a need for water change and cleaning.
Since I switched to remineralized RO water and reduced lights its all been much more stable. Trying to go lush and low maintenance.
I added an Eheim 106 with some tubing from Home Depot. I really like the extra flow. I also like that I can slow the flow for feeding preventing food from getting on the bottom.
Its been two days. My water is very clear now. Very noticeable. 4x the filtration media and added carbon does the trick.
I had the valve on the unit completely open and it stirred all kinds of detritus off the bottom. I left it open to see how the fish would react and to suck out all the muck.With the extra water flow... Tetras like it, otos don't mind, dwarf gouramis seem to dislike it. Everything is peachy with the valve slowing the rate about 25 to 50 percent.
I hung the light on the back wall and took the old filter off.
It's all temporary for now. Moving in a month but here's a shot.
