I use the pinch method, had a "sprinkle" incident such as yours many many years ago.

I've been grinding up Extremes' Spirulina flake, going to get some of the Dr. Tims!

Have they been eating?

A short video from the 20 Long. Large female and a small male at the beginning, later a long fin male and his buddies drop in. We have 2 females' and 4 males (it appears). This female has been the primary spawner. Best viewed at half speed.

This is a 20 long with an Aqueon 50 watt pre-set heater (78). Has a top. Room temp is blue, water temp is green. Temps swings 5 degrees.

Room temp will have an impact, to a lesser degree since it has a top. Is it fully submerged? Depending on when it was made it may actually no be fully submergible.

What are the overnight temps like? Put it in a shaded area.

I'd be tempted to give Seachem Purigen a try.

Open top? Room temperature? Doubt it. Possibly. You should set the thermostat for 80+.

Switch to manual and use this button. You can save 4 profiles for manual mode. I don't see a multi-Day programming option.

Dragon Flies and Back Swimmers!!! Grrrrrrr.

We have bull riding, apparently shrimp have snail riding.

Not sure what light you have but 60% on a shallow 20 long still seems a bit high. I have a Fluval 3.0 on a 20 long and I'm sure it's at or under 20% (I'll check when I get home). You may need to cut back a bit more. I applaud the fact you are wanting to use Easy Carbon for the right reason. If you do decide to use it, do not OVERDOSE! And for sure heed this warning. "Warning: Can be irritating if it gets into your eyes, nose, or mouth. It can cause stomach upset if swallowed. If you get Easy Carbon on your skin, rinse off. If you get it in your eyes or mouth, rinse thoroughly for 15 minutes. For USA customers reference the poison.org website." An interesting read.
