A holder for 2 Maxspect Nano Tech anaerobic blocks, and the slimmest of our 3 Maxspect holders.
Best forHolding 2 Maxspect Nano Tech anaerobic blocks
If space is tight, start here.
The anaerobic block holder is 105mm long and 27.5mm high, the slimmest of our 3 Maxspect holders. It takes 2 Maxspect Nano Tech anaerobic blocks, which Maxspect sells separately, so you add your own when it arrives.
The frame is built to keep water moving through the anaerobic blocks, not just past them.
The photos show the holder with 2 blocks resting on top, in several colours, so you can see how the blocks sit before you buy.
Under the blocks there is a sheltered space for copepods and amphipods to multiply away from fish.
We cannot promise a colony in your tank. Where one builds up, the pods may graze on the bacteria and detritus in the blocks.
This holder is for anaerobic blocks only.
Running bio blocks or bio spheres instead? Our other 2 holders are shaped for those. All 3 come in the same 5 colours, so you can match them if you run more than 1 holder in the same tank.

This is the slim one. It holds 2 Maxspect Nano Tech anaerobic blocks in the slimmest frame of our 3 Maxspect holders, with flow through the blocks and a safe place for copepods below.
Yes, this one, made for 2 anaerobic blocks. If anaerobic blocks are your media, this is the holder to pick. The blocks are not included, so buy them separately.
The frame is 105mm long and 27.5mm high. That is the slimmest of our 3 Maxspect holders, and lower than even the bio block holder, which stands 36mm.

The design includes a sheltered space for amphipods and copepods, away from fish. We cannot promise it will work in your tank. Where a colony does build up, the pods may graze on the bacteria and detritus in the blocks.
There are 5 colours, the same as our other Maxspect holders. The photos show the holder with 2 blocks resting on top, so you can see how they sit.
Maxspect Nano Tech blocks are sold by Maxspect, not by us. The holder is our own design, 3D printed by Marine Spec as an independent accessory, and Maxspect has not made or endorsed it.
To see how a pod hotel fits into a reef, read do copepod hotels work. For the media side, Maxspect bio spheres and holders in a sump is also worth a read.
Pods to start with are in live marine copepods. The other holders are the bio block holder and the bio sphere holder, both in the pod hotels collection.

2 Maxspect Nano Tech anaerobic blocks. The blocks are not included, and this frame is made for them, so check the blocks you have before you order. If you run bio blocks or bio spheres, look at our other 2 Maxspect holders instead.
It is 105mm long and 27.5mm high, which makes it the slimmest of our 3 Maxspect holders. It takes up far less room than the sphere holder. If you need the width as well, message Harry on WhatsApp before you order and ask for it.
The holder provides a sheltered space for amphipods and copepods, with flow passing through the blocks. We cannot promise a population in your tank. If one establishes, the pods may feed on the bacteria and detritus that live in the anaerobic blocks above.
No to both. Maxspect and Nano Tech are another company's names, and the blocks are sold by Maxspect, not by us. The holder is an independent accessory designed and 3D printed by Marine Spec, and it is not made or endorsed by Maxspect.
