Biofilm alternative


fishmosy

Recommended Posts

Decided to try out an alternative biofilm recipe. Really simple, just egg white and spirulina (although in this case I used a powder form of some marine microalgae). Mix it up and coat onto rocks. Leave to dry in the sun and thats it.

Heres an example.

My snail seemed to like it.

Yet to try it on the shrimp but will let you know how it goes.

Interesting.

Very creative dude.

Going to follow this with interest.

You could potentially use all sorts of nutritious foods instead of spirulina or algae.

Very cool idea. I wonder how this would go with Otocinclus cats and whiptail fry.

I'd love to advance my testing of Astaxanthin and Chlorella using this method.

 

What micro algae powder are you using and where did you buy it?

I think that is where this was originally developed from. Feeding finicky plecos and whips. Should work well for pretty much anything which eats from a surface - snails, shrimp, plecs, loaches ect ect

I'm using a dried mix for feeding rotifers. Its a mix of dried nannochloropsis, isochrysis galbana, yeast and a few other nutrients and bits and pieces. The bulk is nanno though, which is a green microalgae used for greenwater in marine aquaculture.

I wanted to see if the technique would work. If I had to buy new ingredients, I'd go with Spirulina as my base - simply because its readily available as well as being a nutritious microalgae.

How long does it take the algea to grow before you drop it in the tank?

Its an alternative to the algae/biofilm that naturally grows on surfaces submerged in water. So you dont grow the algae. You use a dried algae product like spirulina, mix with the egg white, paint the resulting algae paste onto the rock, let it set, and then its ready to feed.

Fantastic ideas Ben, definitely be watching your progress on this. I'd have to agree with jayc on this, Chlorella might be better as it's got a higher protein content than Spirulina. :thumbsu:

I haven't investigated the nutritional profile of chlorella so you are probably right.

I had some food left over which hardened in the glass that I mixed it in. I broke it out and fed it to my CRS. They didnt climb all over it in masses like they do Boss Crack or Snow, but they did eat it.

Yeah, it's got 65% protein, found that out while investigating the nutritional values of the ingredients of my foods, Spirulina has less than 10%. :thumbsu:

Yeah, you can get a 500g tub on fleaBay for about $50-$60. :thumbsu:

I get kilos wholesale, give me a yo if you want me to pick one up for you. :D

Thanks mate. May give you a yell at some point. Got plenty of the rotifer mix for the moment.

Gotta agree with Squigs.

Chlorella is way more nutritious pound for pound (for shrimp that is).

 

The ultimate mix would be 50:50 mix of Chlorella and Astaxanthin.

 

I'm in for some Chlorella if we are doing a group buy.  :mail:

Please let me know.

I realize this thread is rather old, but has anyone tested this further?

 

Is this a viable alternative to the cubes I make with agar-agar? I am bio-film challenged and looking for supplements.

 

Also.... Would the shrimp care if it was "broken cell" Chlorella vs whole cell?

Im geting a product hopefully soon from glasgarten called bacter ae. I watched a YouTube review on it and he talks about how it rapidly created a biofilm

I ordered it from a shop in the states, along with glasgartens shrimplet food and some knettle stix :D

Yeah, hopefully the place that sent it declared it properly! Im sure its labels are all German too haha

The Bacter AE will be the main problem, bacterial content in any products are a no no & technically you can't ship foods in either. I looked at getting the Glasgarten range in a while ago & hit red lights at every turn. :sad:

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!

      Hi SKF!   So I bought some PRL (or at least they were sold as such. These claims are dubious in Australia as people don't know much about the genetics, nor do they care as long as they can make a quick buck). After 8 generations of breeding true, I'm having around 1 in 200 throw a much darker red. They almost look like Red Shadows, but I don't know too much about those types of hybrid. Can anyone help with ID'ing the gene?   TIA (First 2 pics are the weird throws, second photo is their siblings and the last photo is the parents)

      Thanks for taking the time to do the update and photo. Very pleased to hear it is now going so well. Different plants have different requirements so you need to check they will thrive/survive with the setup, light requirement/co2 etc or just get more of what you have, there are various Anubias if you want some variety. The number of shrimp shouldn't affect what plants do well! Maybe just get one plant at 6 month intervals and have another go, things change in time and you don't need many in a small tank, and the ones you already have will grow over time as well. Good to hear you got rid of the scuds, I did the same, manual removal when I had them, but I caught it quite quickly and only had substrate in the tank!

      Maybe it’s time to give some feedback. I forgot the time I could see only 2 shrimps, since then the population has grown so much that I gave 30 of them a couple of months ago. Then again now I think the population went over 120 and I am giving again about 70 of them. Not sure why they died in the beginning, maybe they were quite old. They were fairly big! Or it was the planaria? I got rid of them and scuds. The second one was not easy. It was out of control so I emptied all the shrimp population from the tank and poured sparkling water for a couple of hours. Some scuds survived that! But eventually they disappeared in some weeks after manual removal each time I could see one. My only problem is that plants dont go well anymore.  xmass moss, dwarf hair grass and anubia nana go very well but other plants progressively died. (Not suddenly) - Is it due to shrimp over population? - the sparkling water treatment ?  - i can’t see other issue, i provide generous lighting, co, fertilizer (in soil and in water). I have a bit of algae but under control.
