Anxious to see this working

[crny1]

Look what showed up. Cant wait to see how well it works, especially for the price.

You're going to the future aren't you?


No idea, but it looks very cool.

I saw a flux capacitor too

It looks like something you would see NASA using in space

Oof I bet it’s way out of my price range. Looks really cool though!

What model is that one and can I inquire what you were quoted? I'm getting a quote on the M4 standalone.

I'll give it props for looking expensive. And from germany, it probably was expensive :)

Iv'e seen a couple of videos on these and they look awesome... I know they are used extensively for large freshwater ponds.

How much are these running?

A few years ago, I made a prototype of one of those. I stopped because the juice wasn't worth the squeeze for my 400+ gallon system, wasting a lot of salt water to flush the filters.

I can see them being useful for large systems, but for the average 100-500g system, this falls into the realm of justifying spending based on other factors that revolve around curiosity, conversation peice, perceived cool factor, tech nerd etc. Probably great for the neophile.

Keeping in mind of where I stand, I always thought roller mats were a novelty, this is just that on steroids.

Hmm. I think I like this thing. Can't quite wrap my head around the cleaning of the screen though, and where all the junk goes.

It looks a lot like a pond drum filter, if so, it should actually keep itself clean. The drum rotates periodically and the manifold up the side sprays it off, the gunk then goes somewhere else for later collection

The water flows from the inside to the outside at the bottom, passively, just like a filter sock or roller mat. The drum is always slowing turning, so the inside gets coated a little at a time all the way around. As the drum gets plugged up, the water level rises inside and turns on the clean cycle. The drum is cleaned with a high-pressure spray from the top (using tank water), and there is a small catch tube inside that catches the dirty water and it runs to a drain or a container. The videos I've seen show very little water being used for each cleaning, but of course that all depends on waste load.

Where I think there is a drawback is that you are flushing with tank water, but then add RO topoff automatically which will drive your salinity down over time. I don't know if there is an option to use RO water for the spray down, which would eliminate most of the potential salinity issues but not all. You could also add some salt to your RO topoff water and try to match the loss.

Thanks for sharing looking forward to seeing it in action!

 

[Sm1nts2escape]

Awesome! What size tank and how much$? I thought these used fresh water to flush and not tank water???

I read that you should automate your water change just through using dosing pumps to match the "average daily volume" being taken out by the cleaning cycle of the drum. You would still need to check your salinity just to make sure it's staying constant.

So how much is this? and how many do I need for 1000 gallons

It wouldn't be hard to track sw expended and replace with new. The issue was how much was needed.

This was my biggest problem, you're using saltwater to flush the filters and the sw necessary to adequately do that was more than your average 10-20% weekly water change (for smaller tanks).

I'm curious how this one solved that issue? Or maybe OP has a large system??

At the time, I had a few ideas on how to use fresh water (ro/rodi) to flush the filters, but required 2 setups and a way to automatically divert sw between the 2 when it was time to service. But that further isolates it to larger systems that have plenty of real estate around the tank.

I ask ai to calculate each model for me based on a medium bioload for the tank size corresponding with the model. Here's what it came up with if that helps.

TinyDrum Model	Max Flow Capacity (GPM)	Max Flow Capacity (GPH)	Max Tank Size (Medium Bioload)
S1	~4.4 GPM	~264 GPH	~88 Gallons
M1	~6.6 GPM	~396 GPH	~132 Gallons
M2	~13.2 GPM	~792 GPH	~264 Gallons
M3	~19.8 GPM	~1188 GPH	~396 Gallons
M4	26.0 GPM	1,560 GPH	520 Gallons
L5	57.0 GPM	3,420 GPH	1,140 Gallons

• S1 / M1 / M2 Models: At a brief 12-second flush, these smaller drums use roughly 0.06 gallons per cycle. At 32 flushes a day, they will consume right around 1.9 Gallons Per Day.
• M3 / M4 Models: The wider drum length requires slightly more spray width, using roughly 0.10 gallons per cycle. This checks out to 3.2 Gallons Per Day.
• L5 Model: The heavy-duty commercial L5 uses robust blasting nozzles that pull 0.18 gallons per cycle, totaling 5.7 Gallons Per Day.

So how much is this? and how many do I need for 1000 gallons

Well this one will be going on our roughly 1200 gallon system. This is the L5 and its $8400

Can you post a video of it working on your tank ?
