I would like to change the corner filter in the 100 litre tank I'm setting up for our RCS and some plants, but there's a lot of different views out there. The minimum standard seems to be a minimum turnover of 4 times the tanks volume in a community tank, but what about for shrimp? When the tanks ready we'll be putting in our RCS, plants and, depending on how they go, add some other types of shrimp. I've seen some people recommend going for a lower lph so the flow isn't as strong for shrimps, is that a general rule? I'd like to run a HOB with a bio sponge over the uptake and an air driven twin bio sponge filter as well. Should I go for around 400 LPH and can they be ran with standard filter wool and the ceramic bio stars I have in my cannister filter instead of activated carbon? I don't like using activated carbon due to the problems it can cause. And lastly is it worthwhile getting one with a protein skimmer (I'd cover it with some stocking so the shrimplets don't get sucked in)?

I run hob filters with intake sponge covers aswell as single air driven bio sponges on my tanks , the water is always crystal clear

3 of my tanks are 60L and I run the Aqua one Clearview 300 on them ( recommend up to 80L tanks ) I got them for $25 each

I did look at the clear view 500 the other day for an up coming project , recommend for tanks up to 120L and they where $45 , can't remember the turn over per hour but google should tell you that

In the 300 I have ceramic noddles in bag , 2 strips of filter wool and the plastic bacteria plate ( i don't use the cartridge supplied they are pretty useless ) , the 500 is much bigger so you should be able to put heaps more in.

I find the flow ok with my shrimp , they seem to like riding the flow

Cheers Twelly

I'm a big fan of over filtering & 4 times per hour turnover is the absolute minimum I would go. Don't worry about the current cause the shrimp will just hang out where they are comfortable, my tanks run about 8-10 times per hour & they still hang out in the open. Instead of carbon I use Purigen as it is way better. :encouragement:

Forget about a protein skimmer for freshwater as they don't work, purely meant for marine(saltwater) only! :D

Thank you :-)

I was thinking of going for around 300lph due to what I'd read, limited space, cost and I'd like as much hardware out of site and taking up room in the tank as I can. But reckon I'll go a minimum of 400lph now.

I didn't know that about protein skimmer, only read that some peeps have them on their filter. On our 125lt community tank we were running a 1200lph external cannister, but it was poor cheap quality and after having 2 spring big leaks in 6 months, talked the other half into spending a bit more when I found a better quality 800lph canister filter for $20 more at a closing down sale. The shrimp do seem to enjoy 'riding the flow' in there & 2 RCS in particular can often be seen racing laps around the sides of the tank, one way then back the other way, riding or challenging the flow lol.

Hahaha, yeah I love watching the extreme shrimp, the daredevils are too funny! I posted a vid of one of mine hanging on to some Subwassertang while directly in the flow, he does it all the time, till he gets blown off the climbs back up into the flow, absolute nutters & I love it!! :victorious:

I thought I had lost a few tibees even cleared out the tank looking for them...about a week later I decided to change the filter floss in my HOB and saw something darting about. i removed all the media into a jug of tank water and sure enough tibees! They had climbed up the waterfall against the pressure and lived in the HOB for a week+ in that heavy flow! Gets me thinking if they prefer the flow? Had to lower the tank water so there is now a gap from the waterfall of HOB...

Lol. Starting to think it might be a good idea to see if I can find a way to make room for a bigger filter. Not much room in or around the tank and no where to put an external canister filter as the shelves under the tank aren't very high.

Gave in to impulse and brought another 20+RCS for spare change at a fish auction yesterday and watching them when they finally got to be released was a laugh and a half as they fled their bags and investigated and played in their new temporary home and checked our other RCS.

Found a little external canister filter that actually fits on the shelf in the cabinet. It's only 300lph, but it holds a surprising amount of bio media, which I took out of the corner filter in the tank and the external canister on our main tank. I've set it up with the spray bar, which I'll probably stick with, but I can change it to the diffusion nozzle later if I want to. I've also ordered a twin sponge filter suitable for tanks up to 95 litres so I'm hoping this will be enough. If it isn't, I have another sponge filter I can use as well and our air pump is more than powerful enough to run both. Atm I'm only using the sponge from it over the intake in the community tank

      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.
