You can find pretty cheap pumps on amazon that will work. In Zipgrow towers they generally have 2GPH drippers in them.

The 550 should give you a total of 7.2 Ft of head pressure and give you a bit of extra flow for adding towers

I use this guy:

1" exit pipes are a must if you want this guy on max, .75" if you put it on the lower setting. Otherwise vacuums don't break. Can't say it's not made in china.. never checked. Don't care. Has lasted me years.
For my small nursery/seed starting I use little tubs like that and give air with a 10 gallon airpump. I think they're $9-12 at amazon. Get a good airstone - not those little round ones the diameter of a penny - but get one that is 2-3" around. They're cheap. You cannot circulate too much air.
With a later than few-gallon container, you'll want a water pump to move the water around. You can just get a small aquarium pump and not hook up an output line, turn it sideways, and it will do the job fine.

You can get similar (prob made by the same china shop) at Harbor Freight for $15 sometimes or even less with a coupon.
Cant comment on compost tea other than it smells like poo and I wouldnt want that in my basement where I grow stuff :-)

That’s what I use. Get some hose to go with it like this:

I use this one and it works well...maybe not quite as fast but it knocked my 5 gal wort down to 60 degrees in about 10 minutes.
