This holder takes 1kg of Maxspect Nano Tech bio spheres and lets water flow through all of them, with a copepod hotel underneath where pods can multiply away from fish.
Best forReefers running Maxspect Nano Tech bio spheres who want a pod hotel
The frame is shaped for 1kg of Maxspect Nano Tech bio spheres and held open, so water can move through the whole load.
It is the only holder in our range designed around spheres rather than blocks. The spheres themselves are sold separately, so you add your own.
Below the spheres there is a sheltered space for copepods and amphipods to multiply.
Once pods are established they may feed on bacteria and detritus from the spheres above. We cannot promise a population in your tank, but the layout gives them somewhere to start.
At 191.5mm tall and 83mm square without spheres, this is the tallest of our 3 Maxspect holders.
The bio block holder is 36mm high and the anaerobic block holder is 27.5mm. Measure the space you have before you pick, then choose your colour.
Pick Midnight Black, Scarlet Red, Aqua Green, Clown Orange or Regal Blue.
The gallery also shows a black and orange Special Edition finish, which is the one in this photo. If you want to know more about that one, message Harry on WhatsApp before you order.

This holder is built around 1kg of Maxspect Nano Tech bio spheres. The spheres sit in an open frame so water moves through all of them, and a copepod hotel fills the space underneath.
This holder does, up to 1kg. Of our 3 Maxspect holders it is the only one designed around spheres rather than blocks, so if your media is spheres, this is the version to choose.
The spheres are not included. You buy them separately.
The frame is open, so water passes through the spheres instead of around them. Underneath is the pod hotel, a sheltered space where copepods and amphipods can multiply away from fish.
Once a population is established, those pods may feed on bacteria and detritus from the spheres above. That is why we treat the holder and the media as a pair.
It is 83mm by 83mm and 191.5mm high without the spheres loaded. That makes it the tallest of the 3, so measure the height you have before you order.
There are 5 to pick from: Midnight Black, Scarlet Red, Aqua Green, Clown Orange and Regal Blue. The photos also show a black and orange Special Edition finish.
Maxspect and Nano Tech are the names of another company's products. This holder is an independent accessory, designed and 3D printed by Marine Spec, and it is not made or endorsed by Maxspect.
New to pod hotels? Read do copepod hotels work, then Maxspect bio spheres and holders in a sump. To seed the hotel we sell live marine copepods and the live nannochloropsis phytoplankton they are fed on.
The other 2 holders are the bio block holder and the anaerobic block holder. All 3 sit in the pod hotels collection.

It holds 1kg of Maxspect Nano Tech bio spheres. The spheres are not included, and the holder is made for that media, so check that you are using Maxspect's spheres before you order. If you run blocks instead, look at our bio block or anaerobic block holders.
Without spheres it measures 83mm x 83mm x 191.5mm, so it is square in plan and tall. It is far taller than our other 2 Maxspect holders, which are 36mm and 27.5mm high. Work out where it will sit and how much height you have before you choose a colour.
A pod hotel is a sheltered space where copepods and amphipods can multiply, away from fish. Here it sits below the spheres. Once pods are established they may feed on bacteria and detritus from the media, though we cannot promise a population in every tank.
No. Maxspect and Nano Tech are another company's names, used only to say which media the holder fits. It is an independent accessory designed and 3D printed by Marine Spec, and Maxspect has not made or approved it. The spheres are bought separately.
