CO2 diffuser not working?

I have a Fluval 88g CO2 kit (this one: http://thereefshop.com.au/index.php?main_page=product_info&products_id=2136) and I just noticed that CO2 is no longer coming out of the diffuser. The bubbles go through the bubble counter but nothing is coming out. I took the tube off and there seemed to be built up pressure in it... so it must be the diffuser.

Does anyone know how i can fix this??

When you say 'No longer' i assume it was working at one stage. Its a pressure problem. Most likely youve run out or too low on co2 to force the co2 through the diffuser.

Squiggles i dont think your ment to be able to blow through a diffuser?

Nope, can't blow through it... I tried that!

And i'm definately not low on CO2 cos the reg says the bottle is still 2/3 full... plus the bubbles are coming through the bubble counter, there is just no bubbles going into the tank.

Lol, I do realise that Robert :stupid: but that would be a cheap Co2 system blowing into the tank, I meant just to test if its blocked & stops the flow of Co2. I don't think there is any way to clean the diffuser safely, anyone? :encouragement:

Take the ceramic disc out or put the whole diffuser in bleach to clean it. then rinse it well and try again.

According to this video:

People are waiting 6hrs for the pressure to break through the ceramic.

That's an awesome idea Robert, can I suggest after cleaning with bleach to soak in a solution of 5 x dose of Prime or another good dechlorinator for a few hours :encouragement:

yeah i had the same problem with an atomizer i was using. the bubbles counter and gauge showed pressure and bubbles but it wasnt coming out and the pressure would slowly decrease as the day wore on. i disconnected it to find the bottle was fine when it wasnt connected to the atomizer. i switched for a sera reactor and havnt looked back since. the great thing is with the reactor there is no 'diffusor' for the co2 to go through so when u set ur bubble counter u know that thats whats going straight into ur tank.. just delayed a couple seconds.

after alot of thinkin when i was havin my problem i figured the diffusers are not that accurate. after u see it goes through the bubble counter so u think u know how much is going into the tank... the thing is tho that by the time it makes it way through the diffusor/atomizer stone there is no way to calculate exactly how much is being pumped into the tank after it has been sitting on the stone for who knows how long. just my thoughts anyway. atomizer/diffuser 0.. reactor 1. :p

good luck, i know how frustrating some of these products are!!

p.s i noticed more pH swing when using the atomizer too as the whole tank would go misty at only 1 bub every 3/5 seconds (yes i was only using light co2 back then) now 1bps with the rector.

      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.
