hey ady, great to see you around again fella, cant wait to see what your up to mate.Looks great Iain, love the Congo tetras too, they look stunning under the lighting
Have you any extra nutrients under the sand where the plants are at the rear? Also ive heard of others using c02 24/7, and im setting up another planted tank and am considering this for stability, is this new for you or have you done this on other tanks? Also do you add any extra surface agitation during lights out or is all well without, and do you do any c02 adjustments at water change or does the c02 level rise again naturally at what im guessing is a reduced injection rate?......sorry for the barrage of questions but 24/7 c02 is an interesting topic 🙂
Cheers,
Ady.
There is about an inch of John Innes No3 along with some root tabs around the bulbs, as heavy root feeders they would struggle without.
The idea of 24/7 co2 is new to me also. I heard Stu was doing it and after seeing the images of that tank i signed up to try it pretty quick. It has been set at a pretty slow rate, about a bubble a second through the AM1000, considering the high tech rate was uncountable its a slow and steady amount. For surface agitation, its pretty heavy all the time, i figured i need to off gas as much as i inject to stop co2 climbing to dangerous levels. I would guess that a drop checker would be dark green if i had one in there, which the inhabitants seem pretty happy with. Havent adjust the co2 much after turning it on, i started really low and tweaked it up a little in the first few days but i have no interest in pushing it. I still treat the tank like a low tech with a waterchange every couple of weeks, sometimes longer, surface film lets me know when its over due. Ive also got SAE and ottos to help algae management and the synodontis and barbs help stir up the bottom levels for the filters to do their thing.
Always happy to help if i can fella, be sure to start a journal for your new one pal.
Lights are the normal running level, exposure makes them look brighter, they run at around 20% with the greens and reds a bit heavier. I not sure but my guess is PAR around 20-30 at substrate.That's a nice one Iain. I'm guessing the lights are on full blast when you take photos? Because that doesn't look like low light at all!
