In- Tank Brine Shrimp Hatchery

At NJ Frag fest Erics210 and I were talking about live food for the reef. Told him for some reason I cannot hatch brine shrimp anymore. I did a DIY black box with no luck, see my thread here on it.
Eric mentioned an in-tank hatchery; the salinity, water temp and light would be right from your tank.
I was at the dollar store and picked this up. It has holes on the bottom but glued a cap to it so no egg casing or unhatched eggs float into tank.
I will post back if it worked or not. Pics to follow.

Do you find lots of positives from feeding the live brine ?

Years ago yes. Baby brine shrimp are more nutritious than adult.

This is my first attempt at in tank hatch. If it works already thought of a mod.

I've looked into hatching my own multiple times, but I am lazy in sense frozen brine are loved by my tank enough. But I need to get my brine game up

Paul b had a couple designs even one with an auto feeder for the eggs. They also sell magnetic brine shrimp eggs, so when they hatch, you can just magnet the shells out.

I've got two of these Brine Shrimp Hatcheries

https://www.bulkreefsupply.com/brine-shrimp-hatchery-dish-brine-shrimp-direct-inc.html?queryID=261818b13a670297810fa0a873cf0757&objectID=9677&indexName=brs_prod_m2_default_products

in my possession for more years than I can remember. (Neither came from Bulk Reef Supply nor from Brines Shrimp Direct.) I've never had them fail to produce baby brine shrimp when I needed (that is, when I thought it would be nice to release some into my system). It seems to take less than two days to get naupalii. No power source is needed! Just a light source to attract the shrimp naupalii to the collection spot. Whoever designed this hatchery was really pretty clever! If you're also growing micro algae, it is great to gut load these naupalii before feeding them.

If your naupalii collection device doesn't collect enough of them, add a second or third hatchery - they're cheap.

I made one of those from dollar store items. Cost was under $5 but for me no eggs hatched.

I may need to but new eggs as maybe minec are to old.

So its been 3 days and maybe one shrimp hatched.
I will assume the eggs are bad / old and will order new ones and try again.
