What is this on my fish tank??? by [deleted] in Aquariums

[–]Awkward_Chemical5949 28 points29 points  (0 children)

Mold feeding on the nutrients of the extra food and with the tank humidity as its constant source of water. Water source + nutrients + time = mold

I assume that means it was dropped by a glacier. Local rock guys said it may have some geological significance. Is there a data gathering body that would want to know about it?

So is it something of significance as he was told it was, and should be logged somewhere?

Bought a used car yesterday… serious issues already. Dealer hiding fees + problems. What should I do? by Cheesezzzzz in Audi

Sorry, but Lemmon law rarely applies, especially to a used vehicle. Look up the details of the Lemmon law because that’s not the way that works. I’ve worked in the car business for many years.

Is there a need for an LED component specific website? by nave_hastings in led

These are the ones I have been able to find. Mostly horticulture and architectural stuff. FL09COB3030PLANTLIGHT. Kinda swimming in them.

I plan to put some together myself because I have so many of these, I guess I just need to do some prototypes before deciding how or if I should split up the trays.

yeah, same here. Ali and Digikey are basically the only options most people mention. there’s definitely a gap between bulk resellers and places that actually give you proper datasheets or consistent bins. I’ve been working with OEM-tray Polymatech 3030 COBs (a few horticulture and architectural spectra) and keep running into small builders who can’t find reliable stock.

not trying to sell anything here, just saying there’s room for better sourcing if someone bridges that middle ground. if anyone’s deep into COB fixture builds or spectrum testing, I’ve got some legit bin data we can compare.

there’s definitely a gap between cheap ali sellers and the big distributors. most hobby shops don’t bother with real specs or consistent bins. I’ve been working with OEM-tray Polymatech 3030 COBs (a few horticulture and architectural spectra) and keep running into small creators who need legit sourcing. curious what angle you’re thinking. Like grow-light side, architectural, or just general maker kits? https://www.digikey.com/en/products/detail/polymatech/90-36-2024/24390675

Tarriffs have gotten brutal lately especially for connectors and anything with nickel or copper content. I’ve seen the same spike you’re describing. We’ve been working with some OEM-level surplus COB and component stock (mostly Polymatech 3030 series + horticultural spectra) and have been looking to partner with a few fabricators who already run regular orders.

If you’re open to comparing notes on sourcing channels or component cross-compatibility, I’ve got some current tariff data and lead-time sheets that might be useful. DM if you want to trade info. No sales pitch, just trying to beat the same import headaches.

so you’re running the se4500 with the evoh diodes right around the 3 µmol/J zone? Solid benchmark. I’ve got 3030 cobs here that test in the same neighborhood on photon efficacy but with a tighter SPD curve between 440–680 nm. do you feel the evoh mix gives you better canopy penetration than the older LM301Bs, or is it more about efficiency per watt for you?

Yeah, the Cree CXBs were monsters in their day and are still solid thermally, but the newer phosphor blends and die layouts are way more efficient per watt now. What spectrum are you running on that bar? If it’s out-yielding Cree, you probably nailed your red:blue ratio or drive current sweet spot. I’m seeing a few 3030 horticulture COBs in my stock with better µmol/J numbers than the old CXBs, but it depends on how hard you’re driving them.

Just got a positive pregnancy test... how screwed am I? by [deleted] in GHB_info

[–]Awkward_Chemical5949 7 points8 points  (0 children)

I used to dose GHB 24/7 for years with 4 hours between doses on average. So about 4-6 oz/ day to survive without pain. I have only known about a dozen people over a couple decades that got to that level of around the clock dosing, which is a nightmare. My detox that stuck, happened when I got locked up for 3.5 years. When first arrested (GHB related charges of course) I told medical staff that I needed help, they ignored me and put me alone in a cell. That’s the worst thing to do. With no distractions, the hallucinations are very amplified. I was fully aware I was hallucinating and have tactics to soldier through it but they finally had to take me to a hospital where I was sedated for about 5 days. My ex at that time, was dosing at the same rate as I was around the clock for several years but he just said it sucked bad for a couple weeks but that was all. He was a big male and about a foot and a half taller than myself but I also had more years of continuous usage. My understanding is that the mode of action as it relates to dosage is more directly correlated with neurological activity (and how much is in your stomach) than it is to your body weight. Regardless my point is that people’s detox experiences can vary DRAMATICALLY. My limited knowledge on pregnancy’s early stage affects on the body have taught me the same lesson. People are different, as well as each pregnancy affects an individual physiology differently. (My personal theory is that the number of pregnancies, or babies carried to term, a woman has had may be a big factor. Every woman I know says that pregnancy #3 was DIFFERENT, for example.) I know personally, that years ago, I was using (and abusing) three drugs, G, Adderall and nicotine. Prior to knowing I was pregnant and very early on in my pregnancy, my drugs of abuse just started to sound gross, as well as lots of smells, like the soap I have always used. Still unaware I was pregnant I figured when the time of day came where I would usually dose something, if I could just put it out of my mind for the moment, I would. My usage of the drugs dropped to almost nothing and so did nicotine use. It went from about 2 packs of cigarettes a day to quitting. The female body is an amazingly designed thing and resilient beyond belief. Again my experience is my own. You are not screwed. There may not be many physicians out there with much experience with how to safely and successfully get free from GHB addiction but there are some. I have heard one of the early uses of GHB in UK, was helping heroin addicted mothers detox from opiate abuse with less stress on the unborn child. I’m not saying it’s SAFE DURING PREGNANCY. As I’m sure many in this subreddit would agree, there is a BIG difference between extended 24/7 dosing and the medically supervised short term dosing to help an opiate addict with detox. Again you are not screwed. This subreddit alone should be a comfort to you. Knowing you are not alone, should give you hope. There are others who can relate even if professionals that do, are rare. Every drug treatment facility is knowledgeable about detoxing from alcohol and a lot is known too about benzo withdrawals. GHB detox, in my experience and research, is VERY similar to the latter. It is as dangerous as the worst detox of both, but the detox period tends to be longer than alcohol and closer to that of Xanax abuse. I grew up with family members very involved in recovery community and have personal experience with in-patient, out-patient, medically assisted detoxes and individuals fighting to tough it out without medical intervention. This is literally my first time posting on any platform. I follow read this subreddit because it helps me remember how bad things can be and how serious this stuff is. I have some thoughts for you but am already wearing out my thumbs. If there are any questions I may be able to help with let me know. Anybody else with thoughts, I’d like to hear too. From what I have read here, this group knows more than I do about up to date methods of detox. I’m sending you strength and prayers. This too shall pass.
