I wanted to ask a couple of question about the proper way to trim stem plants and also about the Algae I am seeing on my slow growers. And since a picture is worth a thousand words......I thought photos would help
First off is my question about stem plant trimming.
I thought if I cut a stem between two leaf nodes that it would "split" at the point of the cut and make two new stems....and that was how folks got bushy stems plants. Is that not the case for the particular plant in the photo below? I do believe this is Rotala Indica.
It seems that where I make a cut, the plant just sprouts one new stem and continues to grow up to the light. You can see in the photo below that the new stem is growing great and the little piece left is just dying and turning brown. Am I cutting too high from the leaf node?
In the next photo below you can see that my Glosso is growing straight up and not making a carpet. I do not have this problem with my HC lawn and it stays low and grows out instead of up. Am I not trimming the Glosso in the right place or not low enough?
By the way...I am not sure if I should grow Glosso and HC together like this as I am sure one will eventually win out over the other....but I am new to this and have never grown either plant......so I wanted to see how each grew and what it looked like.
And now for the Algae questions.....
In this photo below you can see algae growing on my Starougyne Repens and in the photo above you can see it growing on the leaves of the Anubis in the background. And on a related note....my Starougyne repens is not spreading either and tends to just grow straight up like the Glosso.
Here you can see the same algae growing on a rock. This same algae also is starting to grow on my glass.
So what can I do differently as far as trimming and also what can I do to keep this algae at bay???
I have a 33 gallon tank with 2x24watt HO lighting suspended about 14~16" above the tank. I am using pressurized CO2 through a DIY reactor and my drop checker is always green (and yes I am using 4dKH solution). Also I have a (rated) 250 gph Eheim Pro3 and a Korilla Nano for circulation. I am also doing EI dosing (1/4 tsp KNo3 + 1/16tsp KH2PO4 + 1/16 tsp K2SO4 = 3 times a week and CSM+B 1/16tsp 3x week) and I add a cap-full or Seachem Iron after my weekly 50% water change.
I have 2 ottos and about 12 cherry shrimp and about 5 Nerite Snails....but I never see any of them eat any algae!!
Any help on these two points (trimming and algae) would be greatly appreciated by this planted tank noobie.
If it helps....here are some other shots of the entire setup.
I bought some window tint (darkest they had) that I will eventually get around to putting on the back glass.....just been too busy lately.
Thanks everybody !
And sorry about the long post (aka mini journal).
