I've put some of the trimmed stems in the middle right which looks a bit odd but but wondering if it will help fight the staghorn algae here?
Where did you get this idea from? I heard it from a lot of people and I never could see the sense of it considering these people also advocate excess doesn't cause algae.
By admitting to this you've indirectly confirm that some fast uptake of whatever nutrients it is, is required. Is that not the conclusion from adopting this?
I'm not saying it's wrong, but it hides a lot of "complications" behind it as a rule of thumb. Another way is to reduce nutrient dosing, but if you are fertilising AIO then you're a bit restricted in what you can control.
They do like high oxygen levels in the water, and though I do inject low levels of Co2 my plants do grow and pearl. I will also set up my airstone for on a night.
One person who I did respect was telling us how he asked one of the top experts on liverworts about their CO2 requirements. Turns out they need CO2 to grow properly and are rather unique amongst plants that required a very high level of CO2. He also stated this was the highest amongst all aquatic plants.
What was this "high" level?
13 mg/l!!!! NOT 30 mg/l (green on drop checker).
So I ask where did you get the idea that your CO2 is "low" and 30 mg/l is normal?
Try 30 mg/l on these gobies and watch them gasp - some fish don't like this concentration and I don't blame them, I seriously doubt it's even seen much in nature.
One scientist calculated that sun light at full blast only required 40 mg/l CO2 for maximum effectiveness to utilise all that light. Or aquarium lights can't even touch sunlight levels - nowhere close!
You DON'T have "low" CO2. You have sufficiently HIGH CO2 - you just don't know it.
What is "low" CO2 then? It's when you DON'T inject CO2 gas into the tank. There is always some CO2 production in a tank with fish and other biological processes.
This 30 mg/l level is retarded, which idiots like George Farmer following Tom Barr and his promoters want to impose onto the rest of us when there are plenty of "low" CO2 tanks with high light that grow plants successfully.
When you are poisoning your plants (and your fish, snails and shrimp) with high levels of nutrients everything behaves perverse and goes into overdrive. By that I mean some plants would die off because they don't like the nutrient levels and other would increase uptake to cope with the toxicity (a strategy known as hyper accumulation which some plant species are known for). Also, strangely enough, some algae die because the nutrient levels are too damn high, this has been observed. High CO2 levels like 30 mg/l and high light are advocated because they want to increase uptake of the excess they are dumping in. And then to cap it all off they can't continue this because it's not sustainable, hence they tell you to do a weekly water change so the fun can start all over again . . . because if you didn't do that water change your tank would be an algal farm . . .
