How to upgrade tank for prawn?

Post by BM »

I finally got a 40 gallon breeder tank for my 17" prawn (m. rosenbergii). Currently he is in a ten gallon tank with an aquaclear filter. I don't plan on re-using the aquaclear filter for the new tank, but i do plan on reusing the gravel. How would I go about transferring him into the 40g tank safely?

Hi BM

This is what I have done before, to set up a new tank and had no problems.

Clean your new gravel ,Very well, to get rid of all the fine particles.
Using of coarse :!: Dechlorinated Water :!: and put it in the new tank and add Dechlorinated water.

Put your new heater in to bring it up to proper temp.

Put your new filter in the tank.
Is it going to be a hang on filter, or, sponge filter ?
If it is going to be a hang on the back filter like the old one,
Squeeze the foam into the new filter for Bacteria.
If it is a air driven foam filter , just squeeze it into the water

Vaccum out the Gravel from the 10 gal.
Put a small amount of what you take out and put it in the new tank Then refill the tank.

Over the next couple of day. take some of the old gravel from the 10 gallon and put in the new tank.

I do a 10% water change each day in the old tank. Putting that water in the new tank.

When you take your prawn and put it in the new tank, I would use the old filter for aleast a week in the new tank.
To help with the Bacteria transfer.

Take it for what it is worth.
This, I have done in the past and have had no problem.

Have a Great Day

17" with arms or just the body?

I've moved my 5" ones to a new tank with old gravel and a 90% water change using tap water and Amquel+. No real issues. When I first got my post-larvals they went into 100% tap water with new gravel and just Amquel+, so I don't think you need to worry. Just be sure there is no chlorine or soap residue.

ok, i just did my first water change in the new tank (25%) about 6 hours ago, now the tank is cloudy. I did another 5 gallon water change and added the old filter back on. Does anyone know why that happened?

Probably a bacterial bloom.
