Tunze Stream Pumps (Which One's?)

[NDJ]

I'm in the process of setting up an Aqua One Windsor 88 (corner curve fronted tank) with a capacity of approximately 330l, glass is 12 mm thick.

I plan on keeping mainly LPS corals and was wondering which of the controllable pumps would be best suited (was looking at using two in total).

Thanks in advance.

I would probably suggest 2 6055's as the best option, but can you tell me more about the tank dimensions?

Tank dimensions are 88 W x 88 D x 70 H (all cm), similar in design to a juwel trigon 350, a difficult shape to eliminate dead spots I think.

I think the 6055's are the best choice for the corals and tank size, I would start with 2 and add a 3rd if needed.

Hi Roger,

I have purchased 2 x 6055's for the tank, glass thickness is 12-mm, I'm finding that the magnets are not holding very well (nowhere near as well my old 6025), I think the pumps are rated up to 19-mm, could it be that I have two bad sets of magnets?

The magnets should be the same as the 6025 magnet holder, all nano streams use the exact same holder. I would guess something is wrong with the holders. The only thing I know of that can cause a weak magnet holder is heat, perhaps at some point they were on or near a radiator or in a hot vehicle. At about 60C they start to deteriorate and loose power.
