"In the shipping box (packed with foam peanuts) it's 36 X 12 X 12 (91 X 30 X 30 cm) and under 20 pounds (44 kilos).

Our office girl just carried one to the post office by herself in her small car,...

Hi:

You might want to make a platform for any brand of nano tank to sit on, that has a upright back with a shelf at the top for the scrubber to sit on. The weight of the tank would make the shelf...

Kcress:

Don't change the color. Air/Sea Rescue Orange *is* the preferred color for marine equipment. For safety.

Hi:

Which LEDs are you using?

Thank you.

John T

"Any particular pictures or description you might want."

I think we all want to see green goo. So do you.

John T

Odd. I run a Linux box and it has never happened to me.

KansasNative:

Sounds like an interesting idea. I would go with the loop side. Cheaper and since you want some algae to stay on, I am sure some hair algae will grow through the loops and stick.

There is a video on you-tube on this very subject.

In the one I saw, they were successful. . .

John T

I am really looking forward to watching this develop.

I wish I had something constructive to add, but great project.

Hi:

I have been reading about carbon dosing and Ultra Low Nutrient systems (ULN). The proponents of ULNs are probably using 'nutrients' in a different sense than is used here, but their thinking...

Hi all:

When I look at the photos, I do not see any Green Hair Algae in the tank either. If the water chemistry if 'off' enough, it may not favor green hair algae and consequently may not grow on...

Hi all:

Are there advantages / disadvantages to running an ozone reactor with an ATS to clear water?

John T

Has anybody experimented with using the nylon pot scrubbing pads often sold in grocery stores? The ones that I an thinking about are green in color, about 3/16" thick and about 4" x 6" and have no...

Nature is still in the stone-age. We can drive to Home Depot!

John T

It is also possible that you disturbed the sand-bed when removed or added water and released materials into the water column which converted to nitrates. Test before and after your next screen...

SantaMonica:

That is a bunch of food and cocktails too!

I think you mentioned it elsewhere, but how big is this tank, how old and what is the bio load?

Thank you:

John T

Kcress:

And I asked politely that people be kind to my drawing, my right-brain has now completely shut down. Sigh.

You have a fine point on bio load and screen size, and as you point out, we...

The lamps and ballasts will set you back a grand, but I suspect that the rest of the build might be on the same order as some hobbyists spend on a skimmer for a large home tank.

John T

Oh yes:

Your flow would be 35 GPH x 48" x 14 screen = 23,520 Gallons per Hour.

John T

The standard rule of thumb would be one square inch of screen, lighted both sides, per gallon of water, or 15,000 square inches.

The most economical lamps are probably 48" T5s or T8s so plan to...

Those plants are just nasty. Why do you even have them? You should take an enormous spray-bar off an ATS, mount it on the bumper of a Hum V, hook-up a party barrel of RoundUp and just kill them!
...

Thank you all for the advice.

Tomorrow I'll make one final trip to Home Depot to get the last goodies for my first scrubber.

I've put it off as long as I can, we don't have cacti in Ontario, so...

Thank you both.

The hospital tank will get 15 lb of rock to keep things stable when I build it.

I'll post developments in a new thread.

kcress:

Good point. Power failures happen.

John

Things have become confused because I now have 2 , perhaps 3, projects in mind.

The big display tank with live rock, shallow sand and ATS only for filtration. For that tank, I think that question...

kress

Thank you for expanding on that. I had wrongly thought that the algae ate the ammonia directly because ammonia is often used in plant fertilizers. That is presumably because soil bacteria...

Thank you for the quick replies and all your efforts on this project.

SantaMonica: Just the information I was looking for. Milestone one would be some growth (oil slick on screen – immediate clean...

Hello all:

This site is an amazing find.

I am about to set up my first SW tank. It will be a 90 G display with a sump. I had planned to use live rock (well man made live rock), deep sand bed...
