Hi,
When I first set up this tank two years ago I had to regularly trim the frogbit roots that would be about a foot long and pull out handfuls of plants every water change. Now, the roots have not grown for months, staying at a few inches long. I initially thought this was a good thing as they must be getting what they need from a short root, after all why expend energy on growing more root than you need?
Now I’m not sure having read that roots should grow luxuriantly to their full potential and short roots suggest a light or nutrition problem. It is true that the volume of frogbit does not increase like it used to.
So should I be looking to increase light and/or ferts to stimulate the frogbit?
Leaf health looks OK to me - but what do I know?!
Tank is low tech 200 litre with 5ml daily of TNC complete, 8 hours of LED light a day (65% brightness though), Water v.soft, no nitrate, ammonia or nitrite.
I suppose I’m more interested than concerned, the other plants do OK but maybe the frogbit is indicating things could be optimised?
Pics to follow
Cheers
