Doing water changes adds CO2 back to a CO2 limited tank. Plants and algae both can and do adapt to low CO2 environments and induce genes to make enzymes that concentrate CO2 around Rubisco, the CO2 fixing enzyme. When we add the CO2 at higher levels back, this causes the plants and algae to...

I would say stop making water changes now that you don't have CO2 injection and just do top ups. Do a water change once every two months or so. Try to point your filter outlet towards the water surface to provide good water surface agitation so as to increase gas exchange. This will increase...

I sometimes have the same problem but I think once it starts growing runners in the soil then it stays there....I cut the runners that grow outside the soil and replant them...

Hi, I have Hygrophila Pinnatifida from Tropica on a piece of wood and it grows well. Can I replant it in the substrate or will it not like that? Is it like Anubias or like Crypts? Thanks

Ok sorry, you said Flourish Excel in this post and I thought I should let you know...

Vallis definitely don't like Flourish Excel!

Hello, I would like to know which plants can be grown without a carbon source (CO2 or Liquid Carbon). I know of these: 1. Anubias 2. Crypts 3. Ferns Whats else in your experience can be added to that list? Thanks

Hello there. Nice tank! Do you have a journel or some specs about the tank please? Thanks

Hi, Does overdosing Seachem Excel cause the hemianthus micranthemoides to melt? If not then what is it causing it to melt? No changes in CO2 or lighting or nutrients the past months....so NO its NOT CO2 deficiency! :) Thanks

So basically it's high light the "secret"?

Ok I will do that then! Good point!

The bubbles per second are countless and they go through a reactor...my filter is 1000 l per h and the tank is 40L....it doesnt make sense...I agree but it doesnt make sense...

Anyone?

Hello, This is a link to my journal where my last post explains a few of my concerns. If possible could you please offer some advice? http://www.ukaps.org/forum/index.php?threads/33795/ Thanks

Hi Clive, how will someone know that the pH shift is adequate according to the kH? I mean if I have a kH of 2 and my pH shifts by 1 unit and someone else has a kH of 13 and the pH shift is by 0.6 units....how will the two compare?

So there is no chance of the ophiopogon japonicus surviving?

Hello, does anyone have any advice for these plants: Parrots Feather , Dwarf Sagittaria, Ophiopogon Japonicus? Especially this Ophiopogon Japonicus I have read it is not an aquatic plant but it doesn't look like it would be able to survive out of the tank! Thanks

I can't see why not...if it doesn't work then no harm no foul...I would read through such a thread if it was about a plant I was interested in...

Hello, what is the plant with the round leaves in this photo? Thanks

Which of these are considered to be hardy?

Suggestions?

Hello, I will start a new 20L nano tank, 7w light, Excel for carbon source and probably lean EI or PPS. I have a list of a few plants to chose from: Hemianthus callitrichoides Hemianthus micranthemoides Limnophila aromatica Microsorum pteropus Pogostemon helferi Pogostemon erectus Rotala...

The tank is equiped with a 7W light. Will it be sufficient?

Did you use the stated dose of liquid carbon or did you overdose to keep algae at bay? What was your fertilisation regime?

Hello, I have this 20L aquarium and I would like to grow Pogostemon Helferi in it. I wanted to know if CO2 is required for this plant or if it will be ok to use Excell. I will be using EI as a dosing regime. Tropica says that CO2 is not required to grow this plant and that it would just grow...

Hello, does anyone know if there are seeds available to grow aquatic plants? Thanks
