Hi guys,

Here is a copy of a project I had posted in another forum a few years ago. I thought it may be of interest for some other people. I ended up scrapping the concept. If I were to do it again I would do many things differently but still, I hope that there is something I can share with other like minded people.

I started studying everything I needed to know (and alot that I probably didnt) in order to make a led setup which simulates sunrise/sunset, moonrise/moonset.

So here goes, I will start from the beginning.

The blue leds emit a max of 23 lux

The daylight leds emit a max of 43 lux

They are 1 watt leds which I like because they cost less, they are more efficient and do not produce as much heat.

There are 8 blue and 8 white in total.

I placed the leds into one of those aluminium strips which you run along the edge of carpet. I used some thermal paste between the led's and the strip and used some silicone to hold them in place. The idea is that the stip acts to dissipate the heat produced from the led's.

This setup doesn't use any led drivers. Instead I ran alot more wiring and put in a few resistors.

I used a length of 40mm pvc pipe and a grinder to cut out the openings for the leds. After this picture was taken I cut up some softdrink bottles and zip tied the cutouts over top of the light openings. You will see if you look at the youtube video I will link with this post.

Here is the link to the youtube video:

The video demonstrates the PWM in action. I sped it up so you can see it fading in and out.

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.
