My fuge was full of this stuff but after about a year it slowly "dissolved" away and I could not find more at any LFS. So I went without for awhile. About 4 months ago A form of calupra started to grow it the display. It took over in no time....it was everywhere
. I tried pulling it out but it would just grow back. Finally about 2 months ago it went asexual twice in two weeks, luckily it did not harm anything in the tank, but most of the calupra died off. I was finally able to find a golf ball sized ball of cheato and put it back into the fuge.
My nitrate and phosphate readings has always been zero but I know that this may be a false reading.
I am happy that it is growing quickly but I will be happier when it slows a bit
