I can grow a disgusting biofilm in my water tubing, but not main tank

Recommended Posts

My shrimp tank has been cycled and up and running for about 2 months now.  I can quickly grow a disgusting layer of biofilm inside the flexible tubing for my pump and filter system, but somehow not inside the main tank.  I say this based on the facts that:

glass is totally clean

intake tube and output spray bar (both acrylic) totally clean

no algae

I suspect this is the reason why my shrimps have periods of inactivity.  They run out of food for grazing and just camp out.  The exception is the cholla log, where I often see shrimp picking at it.

One thing I sometimes do is give the tubing a few squeezes, and this sprays out a bunch of biofilm flakes, which the shrimp don't really seem to care for.

But anyway I would like to know how I can grow a thin layer of biofilm / algae in my tank.  I assume this is the reason why when I go to an aquarium store, I always see active shrimp grazing.

If I change out my lines with a more inert material, will biofilm grow in the tank instead?

I occasionally dose Bacter AE, which is more like a temporary food than an actual biofilm promoter.

      Nope, shrimp import is banned in Australia. Absolutely banned.

      As jayc has mention, do check if you are allowed to import them into your country, I think Australia is ok as long as you applied for the paper work to import them, but do check first. But this option are for those who are after good quality shrimp with a guaranteed of pure bloodline. You can contact them through this email, they accept Paypal with a addition 7.5% on top, their Paypal account email is different, but email them first for relevant detail as they may differ from mine.  YU CRS CENTER CORP. <contact@yu-crscenter.com>   For me they cost with shipping and Paypal fee, its still cheaper them in Hong Kong. I will have to delay this purchase, ADA and the CALs Black Earth Premium substrate are limited now, most places does not have stock, and no delivery date.

      See, and I thought you meant weak solutions were just as susceptible.  So I should pre-mix my 7 gallon tank when I get the RO water and it will last the 4 weeks or so that I use it to change water just fine.  That's what I was after.  Apparently the Salty Bee guys think the same.  Makes sense.

      I was talking about letting pure RO water sit around for too long unused.  Try not to do it.
      RO water that has been remineralised is different.

      Oops did I mix them around?   <edit> - I did mix the names around. Fix it now in my post above.
