Seeding a New Filter

Recommended Posts

ricksza

I currently have a 10 gallon divided tank for my Sakura and Blue Dreams. I'm starting to get all the equipment to upgrade to larger individual tanks. My question is, I'm currently seeding new dual sponge filters in my divided tank, how long until they are considered ready? When I set up the new tanks with the seeded filters, do I add ammonia 4 ppm daily as if I were cycling until I move the shrimp over? How long can the bacteria stay alive without feeding? Should I move some fish from my community tank temporally to keep the bio load up? Any other tips, ideas?

You can add bacteria in dried form or liquid form, and put a few flakes every two to three days, if your parameter are correct, you can have the shrimps in 2 week, but I will give it more time, my 16 l tank took about 2 months.

Even if it's ready, you will still get dead shrimps.

@ricksza is doing it the right way. Bacteria seeded from an existing, healthy tank filter is better than any bottled product. Often bottled "bacteria" isn't the right bacteria.

I'm hoping to use some water from the original tank so the water parameters will be similar, to lessen the shock issue.

What kind of filter are you using at the moment? and what kind of filter for your 2 new individual tanks? i assume you're you'll be using a sponge filter since you're keeping shrimp?

My apologies i've reread your original post and it says you're seeding new sponges. So all you really need to do is cut your old sponge filter in half once you get all the necessary equipment ready for your 2 new tanks and attach 1 half to each new sponge filter with a ziptie, thread or rubber band and It should be enough beneficial bacteria to seed both tanks instantly assuming of course both your sakura and blue dreams and more or less equal in number. if not 1 tank can get 3/10 of the old sponge and the other can get 7/10 of the sponge.

I currently have a single sponge filter in each half of my divided 37 Liter tank. I'm putting 1 double sponge filter in each 75 Liter new tank. That's why I currently have the new double sponge filters in with the current single filters.

That is what I have done in the past as I have 2 filters per tank (different type than above) so use the sponge from one in a new tank taken from an older tank, and leave the new sponge for the 2nd in an old running tank for a few weeks to colonise!

I would guess a couple of weeks would be enough before transferring some shrimp doing this method and using plants and water also from the old tank, though do the usual nitrite/ammonia/nitrate tests first and as long as the substrate is ready/stable by then? I haven't used ammonia but just feed the tank a very small amount of shrimp food every couple of days, and usually add some assassin snails from day 1 as I have those in all my tanks anyway and they don't seem to be affected or die off? You could do the fish method you ask about, I have done this before without the fish dying, but there is always the risk it may die, or at the very least some consider it cruel???

Hope some of this may be helpful but the 'cycle' is a mythical beast to me (that is why I have stayed quiet so far....) as I have never actually seen it happen as it is supposed too.............. ammonia up/down, then nitrite up/down then nitrate up/down??? It could be because I use the same method as you are suggesting here with pre-seeded filters/water/plants etc I guess???

That's the way to do it. Put the new filter into the old tank, and leave it for a couple of weeks. Then instead of using the new filter in the the new tank, you use the old filter. Hope that makes sense. It's a swap basically.

I wasn't going to add fish until the tank was cycled. Add them to keep the cycle going.

Problem is, the old filter is too small for the new tank. I figure if I keep the new filter in the old tank, after a couple of weeks or months, it would be well seasoned to work.

Ahh I see. Well yes, keep the new filter in the old tank for at least a couple of weeks before moving it.

Also, you can squeeze the gunk from the old filter into the new tank to seed it. And you get cleaned filters for the old tank at the same time.

      Here are a coupe of pictures so you can see what I mean, it just isn't going as nicely as before? I can only assume it is the different substrate, still it will get there I am sure and the shrimps seem happy enough and the plants are very slowly growing and going a bit greener than they were. As can be seen in the pictures the shrimp are totally uninterested in the shrimp lolly (or spinach) at this point so I guess there is enough biofilm? It all looks a bit drab, uninspiring and unhealthy? I may remove the Java fern in the middle at some point as I do have another greener (quite small though) bit floating around in an old tank? Simon

      Those parameters are perfect! I think I experienced the same with the algae on plants when I restarted the caridina shrimp tank, but mine seems to have almost cleared up as well - taken months though. One of my failed attempts with tap water many years ago I had PRL and PBL and it did look much more interesting than just the one colour. They didn't live long enough (maybe 6 months) to really know what the offspring would look like though they will still be red crystal or black crystal  so they should be fine together. If one colour does become more dominant then you can always get some more of the lesser coloured ones anyway in the future.. I did get red babies but no babies lived very long as it was tap water! I would try transferring just some shrimps (may be a third) over to the new tank if you are sure it is cycled and see how they go in a week before transferring the rest over? You won't want too many in the tank anyway if you will be messing about with plants/layout still and you won't loose the whole lot if something does go wrong? Maybe also put the Amanos in the new tank for now so the ones in the old tank won't be fitting with them any more for food? Simon

      Update. I filled the tank, unfortunately, there was some melting of plants and some light hair algae( algae is only on the leaves of some plants, nowhere else?). Adjusted my light schedule and intensity. Things are looking better. Did a 70% water change, remineralized with GH+ powder, and clean tonight. Levels are as follows:   PH: 6.4 Temp: 75 GH: 6-7 KH: 0-1 TDS: 140   Wondering  when I should transfer the shrimps... I want to order 10-20 more CRS, and I’m considering mixing in some CBS. I’m not concerned with selling these, so it would be neat to have two different colors. I know the Black coloration is dominant, but, from what I’ve read, I’ll still get reds from offspring in two-ish generations. Someone said expect 25-30% reds. What do you guys think? My  additional plants haven’t been delivered today, so thats a bummer.

      Thanks, the ol' iPhone 6 rarely makes me happy, but if you take enough sometimes you'll get one good one!

      Nice shrimps, I like that blue bolt in the 7th photo, I want one, I also just purchased today another 8 Red Wine to join my other 3 in the tank, along with one amano shrimps and 23 thai micro crabs.
