Fish Crazy
Yeah that blackish algae on the 75 gallon seems to be done "spreading" so to say. Which is good. Its a shame the damaged leaves cant repair themselves.Byron said:On the sword plant question. Difficult algae such as black brush (there is more than one type of this algae) is impossible to remove from plant leaves without literally removing most of the leaf in the process. Some types of algae, such as diatoms, can easily be wiped off with your fingers, but not brush. So if it comes off with your fingers (finger itself, not the nail) fine, but if not, forget it.
Individual leaves will not recover from any nutrient deficiency, generally speaking. As with the algae issue, the aim is to have new growth unaffected. Once you seed this, you know you are likely on the right track. So this is why you won't see improvement on leaves you may have cleaned; the algae has already done the damage.
Removing the older leaves that are yellowing/spotting/veining/dying or are covered in brush algae can be done once you have new growth. How much you do this is up to you. Some nutrients are what we term mobile, because the plant can move them from one older leaf to the new leaves. Provided the stem of the plant where is joins the crown is still whole, nutrients can still travel up and down, so leaving the "dying" leaf may have a value. I tend to remove dying leaves once the others are doing well, but the point here is that you needn't be quick to do so. However, if the leaf stem at the crown has browned and become soft, nothing is travelling up or down so that leaf might as well be removed.
Again, we can't move too fast with changes, the plant has to have time to adjust. Root tabs improve plant growth with swords, but I have never seen this "as it happens," only noticed after several weeks that the plants seem stronger. I at this point would not bother with additional liquid fertilizers beyond the Flourish Comprehensive. It has all necessary nutrients (except oxygen, hydrogen and carbon which all come from elsewhere) and getting the balance with the light sorted out is the task.
Hey Byron, I was a looking for a fixture for lighting and came across this... seems to be just fine for LT for lighting nothing needed like co2 injections, which is another thing once I get good at this ( which more or less means keeping upkeep as a habit and all that fun stuff ).... now that I seem to have at least some success at plants.....
