    Larvae In Leaf Nest On Glass!

    Thanks for the clarification. This might be a dumb question, but an adult Caddisfly is a moth-type creature, but it lays it larva in water? While it's in the water it starts as a grub (like I've seen), and that then grows bigger where it makes a shell out of bits of rock? So is it always...

    Larvae In Leaf Nest On Glass!

    It could be the larva of a caddis fly. So the caddis fly made the nest and then deposited the larva inside to grow. I'd have loved to see it making the nest. I guess that means I still have a caddis fly in my tank somewhere. I'll have to keep an eye open for a moving twig! I recently had a...

    Larvae In Leaf Nest On Glass!

    Anyone ever seen anything like this? I'm stumped. To start with I thought it was a piece of leaf that had somehow got attached to the glass, but when I looked closer I saw it's actually a small larvae (looked like a tiny maggot) which was inside the nest of leaves. See the white bit in the...

    Not scanning, quite the opposite in fact, I read "After all that faffing about I ended up putting the Rhinox disc back in." so I thought that meant you'd switched back to a ceramic in-tank diffuser? Anyway, all cleared up now.

    Also, you've not been tempted to try an UP inline atomizer?

    I notice you've got two drop checkers in your tank - do they ever give different readings?

    D'oh, but congrats on the new arrival! :D Dan-CR4: as a result of this thread I've order a UP inline diffuser and an UP atomizer, aka Bazooka. What I'm quite keen on is getting full flow back from my external filter by using an inline diffuser instead of the external reactor. I think the...

    Andy, Ian, I've no problem admitting I was wrong and you were 100% right, and I'm sorry for my previously (rather rude) tone. I honestly had no idea that so many of the plants you purchase for aquariums could grow in this way! I'm glad I've been set right because this basically opens up a...

    Wow, that's a large-scale operation! And, well that kinda throws my whole debate on its head - it's very possible those plants have Stomata if they're growing out of water and therefore absorb CO2 through the leaves. I'd never seen anything like that. Thanks for setting me straight - I'm keen...

    Get out! I am absolutely gob-smacked that those types of plants would be okay out of water. Would you still need some kind of mist, or are they fine provided the roots are in water?

    To be honest, I've no idea what point you're trying to make here? But anyway... Echinodorus Angustifoliu Rotala Macrandra Ludwigia Inclinata Blyxa Japonica Take any of those out of water for a prolonged period and they'll die - they are not grown "out of water"

    Ian, those are amphibious plants, not fully submersed plants. If you take a fully-submersed plant (the ones I've been referring to) out of water for any prolonged time, they'll die. I'm tempted to try two things as a results of the debate: 1) As you say, I think the flow rate from my filter...

    What Co2 Diffuser

    SuperColey, any resource that says aquatic plants have Stomata are referring to aquatic plants that are rooted in water but grow out of the water - the amphibious plants you speak of. Fully submerged aquatic plants (like most of those found in aquaria) do not have Stomata. I've read the latest...

    What Co2 Diffuser

    I glanced at the links you posted but they don't cover the precise topic we're discussing; whether CO2 in gaseous form can be absorbed by aquatic plants, and whether it's beneficial to have teeny bubbles in suspension in the tank that then rest on the leaves of plants which can then be absorbed...

    @SuperColey I don't think soooooo. Tell me, how do they do it then without Stomata? Here's just one of many many pages on the Internet that say exact the same thing: http://www.eoearth.org/article/Aquatic_plants?topic=58075 "Leaves of submerged aquatic vegetation lack stomata, the pores...

    What Co2 Diffuser

    It's a biological fact that aquatic plants don't have stomata - there's no need for them because they aren't surrounded by gas. So if you deposit a gas bubble on an aquatic plant leaf if wont be absorbed by the plant because there's no physical way for it to be absorbed. An aquatic plant...

    What Co2 Diffuser

    I think people use glass diffusers because it looks pretty having the bubbles and it's easier / cheaper to implement than some other solutions. It might rest on the leaves but that doesn't mean it's absorbed - there's a big difference. Aquatic plants don't have stomata for gas exchange - why...

    What Co2 Diffuser

    "Your second paragraph is mostly wrong. Locical when thinking about it simply but wrong still." No, it's completely right. You do realise that CO2 bubbles hitting leaves is not diffusion, and leaves dont absorb CO2 in that way? The aim of difussion is to diffuse the CO2 in the water. CO2 +...

    Sorry, I feel bad about my last post, I overreacted. It's just I do feel rather offended when I try to offer help, based on actual first-hand experience, and I'm then basically told I'm wrong and insulted by someone who doesn't have the same experience. I've said my piece and made my...

    And I'm beginning to think you're a bit dense. I bought it from them, so that's how I know about the video. Big deal. They probably weren't getting 100%, I am, because as I've said twice now - I've added some foam to stop any rogue, un-diffused bubbles getting out. "just because i haven't...

    What Co2 Diffuser

    If you've not used a reactor then, with all due respect, you don't really know what you're talking about because you've not got the experience. It's very simply to monitor how much diffusion you're getting - look how many bubbles are reaching the surface. The example you posted is an example...

    The Up atomizer sounds pretty cool, but for the price I think I'll stick to my reactor diffuser as I already get 100% diffusion - can't really improve on that. This is just a thought; do you think the Up atomizer get clogged up quite quickly? I know that the tubes from my external filter get...

    What Co2 Diffuser

    They recommend that in the video, and I tried that too, but it's still by no means near 100% diffusion. A mixer/reactor is definitely the best type of diffuser because the gas simply can't escape, it has to be diffused in the water - there's no where else for it to go. It all just depends how...

    I recently bought a CO2 system from CO2Supermarket.co.uk (if anyone doesn’t have a CO2 system I can recommend getting one from there because you can use a sodastream bottle as the CO2 source) and they’ve got a couple of videos on their website where they compare the glass nano diffusers...

    New Tank - Lots Of 'bits' Floating Around

    They say a picture is worth a thousand words, so I've taken some snaps of the offending 'brown bits'. Can anyone confirm what I'm dealing with here? As you can see it's settling on the plant leaves and killing them :-(

    New Tank - Lots Of 'bits' Floating Around

    The theory was since it's brown algae it forms where light levels are low, whereas green algae forms through too much light. The stuff, whatever it is, is brown and therefore increasing light levels may rid it.

    New Tank - Lots Of 'bits' Floating Around

    Yeah the light thing is a funny one; some people say if you get Algae to increase lighting duration as this over-exposes the algae and it dies off, and some people say to reduce it. I guess since mine is on for 12 hours I could try reducing it to see if it makes a difference. However, if it...
