Going down the poly worm hole…

[wednesday13]

I love the PBB’s I wish I had a few of those. I see plastic above the tank. Is that for humidity?

The PBB are def some of my favorites as well. They were my #1 until the congicus showed up. Now id like 12 of each .

I put the plastic up when i 1st moved in 15yrs ago now as precaution for a fish room. Im not sure how much it actually curbs any humidity issues or if it was necessary. It seems to be a great vapor barrier tho. Basement is fridgid in the summers and warm in the winters. I do worry if theres anything behind it. Ive peeled parts back to check and it seems dry and good after 15yrs

My fat Sens like to rest on the over flow intakes. Causing the water to rise in the tank. This is my 450 and it has two overflows. Basically 6 sides or edges the Sens can block. Thankfully I only have 3 Sens
I can see you have 1 overflow centered in your tank, 4 sides. Do you have issues with the polys blocking flow?

Yeah I figured. I had to add an exhaust fan to my fish room. You have a great set up!

Thanks! I put a hole in a block wall 15yrs ago in anticipation for an exhaust and never needed it lol… in my case i found not running a dehumidifier was very beneficial. It threw off so much heat running 24/7 it actually made the room more humid. Saved alot on electricity also. Good lids on tanks and sumps help more than anything IME.

Its only been 2 weeks maybe for any polys re entering the 500 and no overflow floaters yet lol. I drilled it out on all 4 sides. This group just came out of 21” depth to 27” and there still a bit thrown off surfacing. Im sure someone will stick up there eventually .
