I do believe at some point you have to drop some chicken bones on the floor and dance around them.
With the ALR2, is it just a case, maybe, that your tank is already running efficiently regarding the removal of nutrients, meaning that there just isn't enough to go round and make the Runner Beans grow?
I think your exactly right.
My nitrates have been around 18-20ppm as an approximation (mid range test result) for ever, and I mean ages. I only test nitrate every 2-3 weeks as it’s always the same, never moves. I have massive amounts of both mechanical and biological filtration but it neither goes up or down.
So I’ve been thinking about it as you do for ages, and I’ve come to the conclusion that because of the fish load, and I have a few, there will always be a certain amount of nutrients in the water column whenever I test.
The tank glows with life, so I’ve stopped worrying about it. Nopox is dosed at just above the maximum level because higher doses didn’t make any difference other than haze the glass quicker.
I haven’t done a water change since May but I’m seriously considering hooking it up to the new auto water change system with DOS. I don’t think I could bare to get rid of the tank as I’ve spent so much time with it and with a few equipment changes it would be much easier to maintain.
And at night with the new tank it just looks, well, beautiful.........
