Thanks guys, okay I will NOT touch my Aldros then
They are still 2 and 3 inches long, and the bottom ends would die and float off. I have an Utricularia Vulgaris that has branched, but the problem is that it suddenly disappeared, not sure if stolen by a family member or eaten by pests (I saw a rat in the area).
Ken, I am lucky that my Tubs have not had any Algae at all. I am not an expert but what I noticed with the tubs/ponds that I have are:
1. Lots of plants, I of course heeded the advice of the experts and got me some Grasses (monocotes), which is now thriving.
2. Not much fish, only maybe 5 medakas (like guppies) and a few shrimps.
3. No fertilization, except I do inject CO2 from time to time.
I have a bare tub that I am trying to culture some daphnia in, it had clear water like others, but recently I dumped a lot of spoiled fish food, in a matter of 2 days, the water turned green. One word Nutrients. I am almost sure that by dumping fish food in the tub, I polluted the water with nutrients thus Algae thrived.
