Interesting on the CO2 and trace dosing. What trace are you using?
yeah, it's been a bit weird.
initially the HC went mental in terms of growth,then slowed down. over the last few weeks its looked OK, but not amazing.(not like I've had it in the past) but being the avid follower of CEG, i go by his rule of thumb, if plants are not doing well usually its a CO2 problem. so, i pushed the co2. i only presume kno3 and po4 are ok, but trace, I'm always unsure if plants are getting enough especially low growing HC in a tall tank :?
i've also angled the power head downwards so ferts and co2 can be more evenly distributed. with the algae on the stones a couple of weeks ago also gave me an inclination that something was wrong. (i panic at any sign of algae) so from that point i added more trace and co2....1 week on those stones are almost clean again.
anyway, i gave instruction to double dose trace and the HC has brightened up, a trim helped too i think.
the one other thing that contributed to the whole thing must be the mass of stems that were soaking up the nutrients, then i take those out and there's more ferts to go around.
The HC still needs time to really shine again after a trim but it still looks ok
one of the downsides of having just 1 day to make all of these decisions, then leave it for a week.
the trace's are from AE
