Three newbie plant questions: Photosynthesis, Lights on all night, Pruning
I have kids napping in my aquarium room for 2-3 hours mid-day every day. Which means my tank gets 5ish hours of light in the morning, a 2-3 hour break, and then 5ish hours of light in the evening.
Does this break time in the middle interrupt the photosynthesis process? It was brought up on Angel079's algae crisis thread that algae takes about 4 hours to start photosynthesizing once it is getting light. Is this also true with plants? Is it better to have a good solid 8-10 hours of light rather than breaking it up like this?
LIGHTS ON ALL NIGHT:
I took out my light timer (don't remember why) and one night I forgot to turn the lights off. The next morning, my stem plant had grown visibly taller and had lots of new growth at the base. The other plants were noticeably more dense as well (a bulb and a grassy one).
The question is: how does this impact the "whole" tank? CO2 and O2 levels? Fish health? Would it hurt to leave it on all night once a week to promote new growth?
PRUNING: How do you prune your aquarium plants? I have a bulb (Aponogeton Ulvaceous), a stem plant (some sort of Hygrophylia I think), and one or maybe two varieties of Vallisneria, and one Java fern which as yet needs no pruning. (Here's my tank: New Freshwater Tank - 29 gallon Freshwater fish tank)
Do you take plants out to prune? Use scissors in the tank? Pinch off leaves with fingers?
And when you take them out to prune, how do you replant them? I find that pushing the roots into the gravel sustrate as they try to float up while I bury them feels forceful and harmful on the root system.
Thanks in advance, y'all.
On stem plants, pull them up to trim them, then replant the top parts. Stem plants have no root systems comparable to rooted plants to worry about, although some (like Wisteria) do develop quite extensive systems in the substrate.
On rooted plants attached to objects I would just pull the leaf off at the base.
I can back up B. idea by first hand experience that siesta does indeed harm the algae (some types) but not the plant!
I'd also not go for the 24hrs light thing...Simply cause its not natural. The siesta method one could argue imitates a rain day in which its so cloudy there is no sun...but no mater where your fish originate from, there's no place they'll have sunlight for 24hrs (and same for the plants). I'd actually go as far as saying over the long run this approach would hurt your plants (needless to say the fish too)
I don't take non my plants out unless I'm rearranging a tank. The Swords and alike get pinched by fingernails near the gravel and anything like Vallis or Ludweiga I also use the nails and then replant if I want or toss them or add to different tank :-) Specially something like the Vallis that has a wel developed root system and runners pretty quickly I'd not wanna put up with the mess to pull all this out, cut 1 leaf and plant everything again...
Thou I recently considered scissors for the "forest" in my 45g to keep it at a even below surface level if I go do this, I will let you know how it works :-D
[hugs] [kisses] these replies have been very helpful. thx x 1,000,000!
sometimes i just don't realize how much i don't know.
