Jellyfish setup

[safi]

Hi all, looking for some help with setup of a jellyfish tank. I am setting one up with my son but would like to know a few more things while we are still in the first stages before we begin cycling.

We bought a second hand biorb halo 60l tank and it has led lights with remote, air pump and airstone, ceramic media, a small heater and 2 small submersible pumps.

So far we have made our own saltwater using distilled and added marine salt following instructions from an online post. We purchased the biorb marine kit and fitted the marine filter into the casing, added the airstone, the ceramic media, some glass pebbles to go over the media and the saltwater and it is ready to start cycling but nothing else has been added or done to it as yet.

Is there anything else, equipment wise, needed in the tank?

It says online that Jellies need constant moving water to stay afloat and that the biorbs filter system creates its own flow. Does anyone know if this will suffice or will i need the submersible pumps? Or something else to keep the water moving? Dont want them on the bottom of the tank but also dont want them to feel like they are inside a washing machine!

Also does anyone know if there is a difference in the biorb filters? E.g the original filter that you can buy and the marine filter in the marine conversion kits. Are they interchangeable? Read on some forums that the marine kits are a waste of money and not needed but i had already purchased it before coming across this! I will need to purchase more filters but now i am unsure what to buy.

If I have missed anything or anyone can share any tips that would be much appreciated.
Thanks

You'll want to stick with just air pumps for water movement if you're keeping jellies. They'll get stuck in water pumps sooner or later and the water pumps may create too much flow.

Hi , Thanks for your reply.

Yeh I thought the water pumps might be too much for them. I’ll stick to the air pump and stone for now.

Is there anything i can use to drop into the water to get an idea of how much flow there is from it and which direction it goes?

Hello Safi
Was it successful setting up jellyfish in the biorb?
we have just purchased a second had one today and have our hearts set on jellyfish!
So would appreciate any advice you could offer.
Thanks
Rosie

Hi Rosie,

Sorry for the late reply, I haven’t been on here for a while.

Sadly it was not for us! Its a-bit of a long story but the jellies we got (fried egg jellies)were stuck in transit for longer than they should have been and did not survive long.

We ended up buying a small jellyfish tank(which cost a small fortune) and we got 3 moon jellies and had them for around 8/9 months in total but to be honest it was a constant battle. They were fine to start with but then they would either flatten out like dinner plates or curl up into a ball. They hardly pulsed, just went round with the flow and if the flow stopped they laid on the bottom! The only way we knew they were alive is they did eat as we fed freshly hatched baby brine (we did this ourselves with a hatchery kit)and they started to look like they needed a bigger tank! But sadly they started to shrink until they just disappeared(it happened overnight too!) We still do not know where we went wrong as we researched before starting out and got everything that was advised but no matter what we did it didn't work for us. We didn't get anymore after this we turned the tank into a nano marine tank instead!

If you want to know anything else just ask and i wish you luck they are fascinating to watch!

thanks
Safi
