Scruffy that little Ecoplus air5 is a great little air pump, this is my third season using it, and runs nonstop all winter.
Your Trout might get a break tomorrow, they're predicting heavy rain, keep your fingers crossed.
AP - describe your spawning tubs??
Dave I have a 1400 gal. mini pond with a liner so I put 2 plastic oil drain pans about 14in. diameter in the pond filled with river sand and gravel.
The 10 PS's I put in wintered in my 100 gal. RAS, now I'm hoping they'll spawn in the small pond.
There's a male guarding each pan now.
Here's a link to the photo's of them as I transferred them last week.
