Day of recovery and redemption

Today we got an early start, got the bed emptied and cleaned.  Did a quick diagnostic on the bell and found media wedged in between guard and bell as well as the drain was completely filled with Hydrocorn well as the elbow on the drain was plugged.  Cleared all of that out and decided to cut the drain down to 7" from the 8" it was as well as shorten the bell and redo the media guard.  Tested the old guard and the new guard and found that they are not floating, they are actually rising from the media floating and lifting the guard.

Had Conor rewash the Hydrocorn several times while I went out to locate some pvc and cpvc parts as well as maybe a comercial media guard at the pond fish store.  No luck there but we did pick up a water test kit, and got some hardware from Lowes.

We redid the tank, bed and piping.  Put the media back in the bed and started from scratch retesting the set up.  Here is a video of the drain of the bed and it is quick.  I am still concerned about the fill rate vs. the drain.  The bed fills currently in 3:53 seconds and drains in 33 seconds.

We are going to let it run for a few hours, change out the water in the tank and test again.  Should be moving bed indoors tomorrow and get plumbing done

The hydrocorn is no longer floating away, hopefully it will stay.

The new drain incorporates an aerator on the last horizontal section, getting more Oxygen into the
tank.









The grow bed is no longer floating and the water now stops about 1/2 to 1" away from the top of the grow bed.
