Could I slow down the plant growing by stop suppling CO2?

[arash53]

My thank's foreground is already covered with HC ,and all other plant grow fast and I have to keep trimming , if I stop suppling CO2 my HC will die or just stop growing ?

Rather than stop completely, maybe slow down the amount of CO2 injected?

what you can do is raise the lighting, or if its a twister bulb, less wattage. Once the plants are given time to adjust (couple weeks with crypts, few days with stems), you can turn down the co2 a bit. I wouldn't recommend going off of it until you have your plant growth slowed significantly with the lower lighting, it keeps the algae at bay.

So instead fo daily dose , I could dose 2 days a week right?

Light is LED and its in the canopy , I cant really do anything with light.

How do you trim your Pennywort? Mine grows quite fast so I've been wrapping it around a ordament I have in the tank. But after a few wraps, it gets out of control and then starts crawling along the surface.

I keep trim from the top and twist them every week.

Can always block some off with a tin foil or something? It should be save with LED which does not too much heat.

3 Things that make plants grow successfully. LIGHT > CO2 > FERTZ

If you limit 1 of those then the plants will have deficiencies... which limit growth, but also health.

I think light is above all the biggest thing you want to affect, if you limit the light it limits the photosynthesis.. even if you have an abundance of co2 / fertz .

Most people overdo the light anyways.. so ideally to slow the plants down, try to limit all 3 aspects.. a bit and see.

Of course, you could keep trimming and just sell off the trimmings for a nice bit of cash...
