Yeah, that album especially always gives me the right mindset during this time. Candle in the window is another personal fav 🙂 .

A I think it'll work, will be slightly easier with a 10G tank. I don't know how much flow you specifically need as opposed to air stones, decent circulation, and having the rock pile. I always kept mine with just good conditions, but didn't have the rocks setup for them. Looking at your current setup I might try to add some slightly smaller rocks to fill some of those voids or give them something slightly smaller in diameter. Rachel O'Leary's tank is a great one to look at it you haven't seen it before.

This is from the last time I had to swap substrates. It's a lot easier than most people think and it sounds daunting, but no biggie. Take all the decor out. Plants stay wet. Keep the filter media wet as well. Get a tub, considering the size of the tank as opposed to a single bucket. If you have to use multiple buckets that works too. Try to have a towel or lid and then divide the fish out. Put them into a quiet place where shadows and the buckets won't get knocked on. Adding an air stone is helpful as well. Clean what need be, then rinse the substrate and add that in. Fill the tank back up, turn the filter on, let it run and then add everything back. Essentially can be done during a water change!

Not sure why.... Saw this and I can't help but think MTPK has a little Santa hat for this puffer. 😂 Awesome Gif

Anyone here have both lifehouse and blue October on a playlist?

They are really awesome. Very nice pattern.

😂 Sharks are the best. Always around even when you don't see them!

I have 2 Albums I play for myself every year. This one is one we had on CD, 2-5 times over. Had it on tape and played it in the old Jeep before life got a bit too hectic. It'll always remind me of those times and moments with my mom. Needless to say it's a special song and one I don't think many people have heard so I wanted to share it. From the same album, there is a part of one of the songs that is uniquely special this time of year. I'll post the lyrics below: Please feel free to post some of your own favorites. If you happen to feel like posting why, by all means, but I totally understand some memories are your own and very personal 🙂 .

what app or measurement method do you have? I am guessing that's your thermostat or electric company?

MAN I hate that I have literally zero local shops. Beautiful shop. I spy a shark!

I honestly think you'd probably be better with pathos for this application.

I have two of them I think a lot of people might not happen to click on, but they are phenomenal movies. First, for the person with a bit more patience, wanting to see a very well made classic. I believe I saw this on the HBO app, but can't be sure. https://www.imdb.com/title/tt7686464/?ref_=fn_al_tt_4 Secondly, for literally anyone.... Really good one we watched today. (available on Netflix) The ending and message of the movie was really special. https://www.imdb.com/title/tt10187208/?ref_=nv_sr_srsg_0

I would have to see the rhizome to really see what's going on. A few questions would be what are your water parameters, lighting parameters, dosing schedule, etc.? The anubias is basically unhappy, there's a few things to do to correct this (part of that being to remove dead parts). If you can, please try to attach more photos and let's take a look at what's going on. Any leaves that are not fully formed, please try to delicately remove as they are not helping the plant at all.

If you're not seeing results, just try a different one. Very useful for some plants to have those!

Prefilter goes into the sponges, course to fine, then your filter floss or polyfil, then your ceramic media or other biological filtration, then your chemical media. After 3-5 days you'd expect to see it dirty, but you can basically run it for 7-14 days without much fuss. Keep an eye on bypass and the filter not flowing when you're first learning how to use it.

Mentioned in this video with an example. It might be fish TB?

Merry Christmas @Johannes Merry Christmas everyone!

I hate when that happens. So many bugs on mobile for no reason. Weird stuff is always happening. No worries at all, I think it was a hectic time for a lot of us! Hopefully it's a good weekend and holiday for everyone at least!

Add an airstone or two just for the sake of it at this time. Hopefully things level out for you soon!

Let me grab one of Cory's older videos. What is the footprint you're working with? Old design: Lighting the tote, not the room, basically. The lights would be similar to how the wood is used here, two across should work for something like this because your LED beam angle is 120 degrees. New design: Lighting the room, not the tote, basically. Exactly. Single atom thick nano electronics exist as well as using layers of graphene to cool a car engine. Not public yet, but it's technologically possible.

Finally found the terminology I was looking for. LOL. (Falloff) Basically you're talking about a short throw (I think you mentioned sumps) but you need a slightly decent angle to reach the edge of the tank. You want a focused design so you get enough depth because it's a big tank. The question is ultimately whether you move the plants up, floating even, whether you have a large spread or a focused beam. I don't fully understand your layout / tank requirements, but just in terms of lighting and some of the posts in the thread I thought you were setting up a bigger tank for an aquaculture setup? wavelength does matter in terms of refraction, but not as much as other things. Air gaps, layers, lens / directionality of the light matter more than purely what wavelength. The angle in and the angle out is basically the challenge here. This is a really good resource if you want to learn the technical side. https://www.rp-photonics.com/refraction.html

I think for your use case space is actually a challenge / design parameter.

Kessil is 90 Watts, the AI is 55W, the fluval is ~32 watts (at this specific footprint) I think kessil has a lot of custom sauce going on. They have a patent or something on their little array and they tweak / copy paste it on various industries. A more traditional COB design would be like this: (again, very similar to the kessil in design, but it is one type of LED)

I was looking at some other things, but the equivalence here is not really connection (I am curious why you ask!), but also design package and the lens itself. I don't think the Fluvals really have a lens, while the others have reflectors and lenses. Kessil looks to be COBs (I believe) while the fluval / AI looks to be SMD designs. Both of them are basically equivalent, it's more about efficiency and size as opposed to anything else. https://www.digikey.com/en/articles/the-basics-of-chip-on-board-cob-leds https://www.solarlightsmanufacturer.com/cob-led-smd-led/ Edit: Here is what I found as far as the engineering design of the AI lights, I'm going to assume it's similar in scope to this product: https://media.osram.info/media/img/osram-dam-7411798//LED_Engin_productliterature_custom_LuxiGen_emitters_rev2.pdf The Kessil definitely looks like a custom COB design they are using, but it also is a variety of LEDs. Having the adjustability means it cannot be a COB design, as mentioned above. They have a wide range of products for various industries that all use this same design. Goliad Farms would agree heavily.

Well, it's non-technical and a ton of PR as opposed to engineering, but here's the rundown. Something like fluval uses a beam design, while AI/Kessil use what I would call an LED array design. This isn't some mind breaking breakthrough in technology, very old stuff, but it has it's own flaws and issues. Let me compile a few things for your review and then feel free to ask if there's anything I potentially can help with. From the Kessil PR dept: https://kessil.com/about/technologies.php From Pecktec showing his lights: You can tell by the age of the video about the technology and difference between current and past products (they changed a connector and some of the board design). Here is the breakdown from Aqua Illumination: Spectrum Charts: Fluval Aqua Illumination Note: you can see how this is MUCH MORE even spread. Kessil Design Comparison / LED Layout: Preface: https://www.ledsupply.com/blog/led-optics-explained/ Aqua Illumination: This is similar in design to the Kessil, it's a very tight array of LEDs, but I would call this a mix between the fluval and the Kessil design layouts. You see the grid pattern and a spread of the LEDs in a specific pattern. What is key here is that each led has it's own lens as opposed to one lens for the entire light array. In terms of refraction, this is a more direct focus of each LED and in particular allows for each color spectrum to have different focal points on the lens. Kessil: There is a lot of time here designing the LED array lens. This is something that is due the sheer size of the LEDs. It's difficult to specify which is the "best approach" because you have 1 point of failure here as opposed to the above design where each LED is it's own point of failure (alignment tolerance, air gaps, etc.) What I can say is that because this is a smaller package, the LEDs are smaller, they are guaranteed to be less powerful as a result. Probably a lot more efficient, but the overall output would be more limited in range because it's trying to do so much in such a smaller footprint. However, it is clear the Kessil has a lot more LEDs in it's array design compared to the AI. More on this at the end. Fluval: Beam design here. This is a lot cheaper (more forgiving) design because you do not have to have an array with ridiculous tolerances. This is still an array of LEDs, but it's simply a much bigger array and with much bigger (cheaper) LEDs. While you might have a precision instrument for the purpose of brain surgery, sometimes you don't need to use a scalpel to open up something when a pair of scissors works well enough. So when I say "cheaper" I am specifically talking about the design in terms of engineering cost. In terms of design, Tanks are rectangular (usually) and this design opts for a much easier spread as opposed to a very focused hotspot. There is a hotspot, but it's going to be a rectangular shape across the length of a tank as opposed to a single, circular spot. What this means is that as you play with the channels, as you adjust things, you can't control the light as well because that channel might be spread. One nice way to improve this design is to use something like dimming arrays as used in the TV industry. This would mean instead of just intensity, you could control the intensity of each channel across a grid. (imagine the lightbar split into 4-8 section and each channel as has even array in each of those section. Currently you're adjusting "red" but in a future iteration you might be adjusting "leftmost grid, red channel" of light. Secondly, LEDs are spread apart, so passive cooling only here. the others will have a heatsink and fan on the board to cool the hotspot of the LED array, this one might have a heatsink, but there isn't a fan and there isn't going to be any noise from these lights.
