Hello everyone,

I'm currently setting up a 3x18x18 tank for my cherries. I will have a couple of dividers in there so that I can separate my chocolates, rilli and blues. In each section I'm looking to have a twin sponge mounted to the back but instead of using an air pump I'm wanting to attach it to the intake of my Fluval G6 which will be running the tank. I will have 3x twin sponges all connected to the intake and thats where I'm getting stuck as I have never done this before with more than 1. I have attached two very dodgy sketches of a couple of ideas.

Having the sponges running inline, Im a bit worried that the closest sponge will have more suction and the furthest away will have minimal.

Having all 3 sponges connected to the same length and then connected into 1 that runs to the G6. Seems this will work well and give the same suction at each sponge filter. Issue is that I may have to use a smaller diameter tube and then increase it after they join up and it will be messy. Im hoping to have it all nice and neat.

If you have any other ideas on how to do this please let me know?

I'm also making a custom spraybar that will be 850mm long. It will be made from 15mm high pressure pipe with a T piece in the centre so that flow should be the same across the tank. I will have 15mm end caps so that the water doesn't run out the ends(duh), I will also be drilling HEAPS of holes along the front of the pipe and a few along the back so there are no dead spots of flow (no BBA behind the spray bar hopefully).

I also have a pretty cool idea to make some dividers (well I think so at least) and once I have them made up I will do a little DIY on them.

Any ideas on the how I would complete the above would be great as I don't want to commit to one and find it wrong and won't work right.

So get your brains pumping :)

Cheers

Trav

honestly...?!

sounds like a huge mess you total flow will be diminished big time...

lets get to the nitty gritty .. a longer spray bar will slow water flowing out big time unless its tiny. which will have more chance of it being blocked..

the 3 intake thing i can see being a prob too as the filter will be sucking in a little from each tank.. unless you shrunk all the hoses down to a 3rd of the original size.(Factory made size)

you would also need taps on each intake to keep all of the sucking the same..you will also never be able to tell if one blocks up..plus you would have to put each one in a bucket first to check they area all sucking the same..

ok, ok... now

this could all work better if you just used a sump..

or you put the intake on one end,and the outlet on the other.. then just make surewater can flow throuh your dividers and add a sponge filter toeach section to to help filtration..

thats what id do anyways..

Hi honcho,

Thanks for the comments. A sump is not really possible in this case. The dividers will allow plenty of water to flow through but i did not want water entering one side and exiting from the other.

I don't think the spray bar will cause any issues as there will more holes than standard so the current produced is no where near as great. I believe 1000 litres p/h will be far to much out of a normal spraybar.

To add to what I'm doing above. I will be using 12mm I/D tubing to go from the sponges and then using an adapter to 18mm(which I believe is the I/D of the G6 tubing), then joining into one and running down to the G6 itself.

It should go OK, but just keep an eye on the sponge of concern, when it starts to block it will suck in or shrink a be, the solution is, clean the affected sponge.

I have seen similar set ups and that was the only draw back, OH and they ran you first design.

Thanks Bob,

With the inline sponges I thought the suction would always be greater at the closest sponge as the water will always find the easiest route. This will be the easiest do I might give it a try this weekend. Finding a 3 into 1 adapter is not so easy for the second diagram. :(

It'd be far easier to just run an oxygen pump with 4 outlets for the sponge filters.

It would also give better filtration having the G6 and sponges running separately.

Agreed It would be easier to run them by air. Most of the time I use a couple of bigger foam filter in my shrimp tanks, the ones that have filters that is. Most are 60cm x 40cm x40cm with nothing, no filter no air.

Are you just trying to shrimplet proof the intake?

Yes, trying to shrimplet proof the intake but also for the shrimplets to feed off of. There will be a couple oxydators running in there for oxygen.

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      Thats a great photo, beautiful blue bolt, I hope it survived the molt without dropping the eggs! I think I can just about see some black dots (eyes) on the central egg but can't be 100% sure. I used to (and plan to again) do weekly water change of 10-15% but if you do too large or quick (not drip in new water) that would likely trigger a molt. What KH are they in, my new setup is sitting at (and refusing to budge) KH 3 and PH 7.5 so I may have to settle for neocaridina shrimp this time as opposed to the caridina I want, though not looking/deciding just yet, give the tank a bit more of a run in! Tap water here starts at kH 14, tds 320, when filtered goes to KH 0 and PH 6 but when put in the tank keeps going to KH3 and PH 7.5 despite 3 x 50% water changes???? You may be at 'maximum capacity' with only 20L tank especially if the tank is a cube type rather than shallow type?

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Right now this tank only has blue bolts and golden bee (red bolts?).  The eggs start off all brown, but at the end, I notice that some are kind of a clear pink-ish color.  So I don't know if that is the egg color of dud or golden bee.  Picture of shrimp only about half hour before molting. The water is always RO + remineralizer, so it should be ok. The tank seems to still be on a "good streak" ever since I started the regimen of weekly water change, monthly gravel vac and plant trim.  The point being to keep the amount of waste low and removing moss / floating plants so that the nitrates go towards growing algae.  At one point, I had three berried females, but only netted about half dozen babies by the end, due to this early molting problem.  There might be about 30-40 shrimp total in 5 gallons, but still very few full-sized adults.

      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?
