Your lower holes look a bit high, unless you plan on unusually high substrate levels.

For this tek, I will be using a 66 quart Sterilite 1928N from Wal-mart. Different sized tubs will require different measurements. So try to understand what I'm doing and not just go by the exact measurements. I'll try to remind you of this as we go.


You are going to have a total of 6 holes in this monotub. 1 hole at each end, at the top, under the handle. 2 holes on each side just above substrate depth. Here's what the holes will look like:


You may be asking yourself "How do I know how high my bottom holes should be? I don't know how deep my substrate will be."

There are few ways to answer this:
1) L*W*H=V, solve for H. If your math skills suck, or your tub is not square, then:

2) Just come up 4 inches from the bottom. A typical substrate depth is 2.5-4 inches. Or, if you want to make it a little more complex, then

3) use water to mimic your substrate. Trust me, measuring up 4 inches is the easiest way to do it, though. But I will explain this anyway because people ask.

Since I use 1 brick coir(650g), 2 qts vermiculite, 4.25 qts water, and 6-7 jars of spawn, I end up with about 14-16 qts of substrate.

So, I poured 16 qts of water in my tub. This gives me about 3-1/8 inches. If I had put the bottom of my holes at 4 inches, I would have almost an inch of head room. It would have been fine because it's not an exact science and i would have room for a casing layer if I wanted. In a tub this size, 1 or 2 qts does not make a significant difference in depth.



I like to put my bottom holes so that they split the length of the tub in to 3rds. This tub is about 22 inches long at the water line, so the holes will be about 7 inches from the ends and 8 inches from each other. Again, not an exact science and your numbers may be different if using a different tub and depth. Just split in to about 3rds.

Mark the the water line and hole spread. Then dump out the water.



Since I want the bottom of my holes to be about an inch above my substrate, I need to move my marks up an inch. Remember? The water line is approximately the top of my substrate. I labeled them because I brain fart sometimes and don't want to drill in the wrong place.

8 inch substrate  will work well, but the currents are gonna be off a bit.

The tyvec pops out, could be replaced with polyfil, SFD, or nothing at all.

I couldn't find documented journals with this type of filter used. I have more tyvec available at this time than polyfil, and polyfil unless felt tek, just seems like a burden.

The room has my air handler, and a sump pump in it. Being said I would prefer tyvec from what I have read and come to understand.

Thank you!

What are your thoughts on SFDs, instead of tape, or polyfill

mp tape/looser poly for chambers.

or to keep it simple.

tape on tubs

did you think this was the correct thing to do? can you link to the instructions you followed, as if this was an actual instruction/advice we could put a warning into that thread.

I have used SFDs, but they were very thin and easy to breathe through, most I see nowadays are big thick ones and so people will presume that is what you are using, and they are unsuitable.

Use micropore tape instead of polyfill. I use 2 layers on the bottom holes, and one layer on top
It dials in pretty well like this, you can add/remove layers if need be
