Sea shells in a fresh water aquarium

Recommended Posts

Hi Guys,

I've just been down in Tasmania and picked up some cool shells on the beach and was thinking tying some moss on to them would like pretty cool in my shrimp tank. I'm just wondering if I can use beach shells in the tank and there wouldn't be any side effects?

Sea shells are made of calcium carbonate.

The side effect is that it will leach calcium and increase TDS.

You will need constant monitoring to ensure it doesn't cause your water parameters to move outside of the shrimp's ideal requirements.

And it will eventually mean constant water changes to rectify the imbalance in TDS.

 

The smaller your tank, the more impact it will have.

 

It might not be an issue if you have a large tank and only add a few shells.

Also not an issue if you have very soft water, and want to raise it a bit.

I will through a spanner in the works.

 

It all depends on the water you start with, what works for one will not work for another in another area!!!

 

For me up here, my water is like rain water, so I use Coral and shell to lift the TDS and in turn the PH.

 

So Know the water you start with and work from there.

 

In a nut shell, some have water like rain water and for others it is liquid concrete (poor buggars), so knowing your starting  point and what water you have is number 1.

OH forgot to add to, some critters are more forgiving than others to.

Larrymull, for the record if you're in the eastern suburbs you probably have very soft water as Bob describes. Cherry shrimp are among the "more forgiving" critters while Taiwan Bees are not.

Yep Kizshrimp I'm in inner east of melb, still all sounds a bit tricky for a piece of shell

I recommend staying in your comfort zone with this type of thing. The good thing about water conditioning products is the instructions, while the alternatives like shell grit are totally uncontrolled as JayC pointed out. I'll bet Bob has a good feel for how much coral to add but that's not for everyone. Me included :)

LOL, the more coral you add the higher the reading. What works for me may not work for others and what works for you may not work for others either, its hard but worth the effort.

 

Knowing your water that you start with and what you want to keep, will go a long way to being successful with anything,

 

Not a lot to do with the topic, but putting the spanner in there again.

 

The good fish farms up here try lots of species and stay with what works in there water, but there is always exceptions, one farm that breeds many 100s of thousands of Neons also produces lots of Electric Yellow in the same boar water??? total opposites of the water scale, works for them big time. Fishmosy AKA Ben has seen the operation

Love those spanners, wow that's a surprise Bob! Do you know is their bore water hard or soft? Curious which species is out of its comfort zone... 

 

btw If I'm keeping africans or other hard alkaline water stuff I don't mind using white rock, coral sand or those type of substrates. With soft water stuff I much prefer to dose to the right levels manually.

Hi Kriso

 

Not sure and will ask for you, the species list is big for the amount of people working there, 3 and some times 4, They do a lot here is a few.

 

Rams

many Tetras

Angles

Rainbows of many species

Bristle nose

Platys

Sword Tails

many more to

 

So there is a lot of fish out of there comfort zone, but the good thing about most of the common species we keep, the are domestic now and way out of there zone so exact water is a thing of the past.

 

There is photos of the farm in one of mine of Fishmosy AKA Bens threads somewhere, have a look its a big farm.

 

One of the amazing sights is to walk up to a pond about 2.5mts across and 600mm deep roughly and it can have 12,000 Neon's in it, or one that is 1.5mt deep and it can have 3 or 4 hundred LARGE Angles in it, 5 to 7cm+ long Angles, I took photos but they look like 3cm fish nothing to give prospective

      Sorry to hear you have lost a shrimp. How many are there left in the tank? I wouldn't act to hastily and start treating for something that may not be? Maybe it just died and you will never know why if it had no symptoms? Just keep a close eye on the rest for now! Maybe the BKK weren't very healthy to start with if they hadn't grown as expected, though also there may not have been sufficient food, but that is less likely if the others in the tank have grown! I would feed the shrimps as the grazing area is fairly limited (I assume this is your 80L divided into 4) but sparingly, maybe twice a week. Crush up a pellet into almost a powder, then dip a pin or similar a couple of mm in the water, then into the food, then back in to the tank will give them something different to eat to supplement their diet. I would check the temperature of the water as well as when my old setup overheated they started going an orange/pink colour? It is good that you obviously spend time watching them as they are fascinating to watch and very calming!  Simon

      Perfect. I've got a spare heater, can source a tank and filtration, have cycled media, and have a simple light if ambient light isn't enough.  Pretty random question - are sponge filters super noisy? I've never used one with an air pump, and the qt tank would go in my bedroom; but only if I could actually sleep 🙂. Otherwise, is it cool to turn off a filter at night? Cheers
    • jayc
      Usually a week or two should be enough with careful observation to see if any symptoms develop.   No. But it depends on the filtration. If you use a mature filter, then you don't need to cycle a quarantine tank for very long. I just use the water from my water change to fill a quarantine tank. And some old filter media floss from a mature filter in the quarantine tank's canister. The quarantine tank is very basic, no decor, no substrate, nothing. Except maybe some lights to check for diseases after a week or two. You can get away with lights, and use a hand held torch even.  Just a heater.

      Thanks for the advice guys, I really appreciate it! As for the details, the tank is my 110L community, and while none of my fish are especially expensive or special, but I don’t want to lose any or have to rescape. The reason I was hoping to avoid qt is bc I don’t have a spare tank or filter atm. I think I will qt I think. How long should I do it for, and do I need to cycle the tank very long?

      Hello folks, This is in regards to my TB tank that has had shrimp for about 2 months now.  The shrimp came in two batches from different vendors - one was two BKK and the other was a bunch of RWP and BB.  Everything was going well for about 2 months with the shrimps actively grazing around and suddenly I found one of the BKK dead and upright in a corner of the tank.  I usually do a check-up on the shrimp every day and the only time the shrimp are inert is one day before and after a molt.  In the past when I had shrimp die for various reasons they would be inert for a few days prior. The water parameters are the same as usual: Amm/NO2/NO3 = 0, ph = 6.0 or a little lower, GH 5, TDS 110 Using RO + SS GH+ and I did a 15% water change 2 days ago, dripping in the new water. I haven't fed any pellet shrimp food for a while because there are still lots of patches of algae in the tank, plus one IAL, plus they finished off a mulberry leaf 2 days ago. Nothing looks odd on the dead body of this shrimp (no real color loss) except the clear parts like antennae and tip of tail are a little orange.  (I think this is typical of shrimp that have died?  Or a molt shell once you remove it from the water and expose it to air.) The only odd things about this shrimp are that in the 2 months, it molted a few times but never grew much (or at all) over the original 1/2" size.  About a month ago, the white parts of it started turning blue.  The other BKK that came at the same time also either hasn't grown at all or maybe just a tiny bit, and only has little patches of blue.  The other batch of shrimp from a different breeder (RWP and BB) have grown significantly over this time. Anyway, the rest of the shrimp seem to still be doing well and actively grazing.  (Actually, two are acting quiet, but it is still within the pre-molt time frame) I hope it's not bacterial infection, but what can I do to prevent / prepare?  I have available: Dr Tim's Eco balance, Doxycycline (fish med), oregano oil, melafix, H2O2.
