How do you get good circulation for your betta tank?

[Fae]

I'm struggling to find the balance between too much current and dead spots in my bettas 10gal.




It's a pretty new set up, so it still has some growing in to do. (The Aquaclear20 was run on my established 50gal community for a week before adding to this tank). But already I'm starting to notice where there just isn't enough circulation moving things around. I'm kind of paranoid of it as that was a contributor to my last betta getting sick, that's also why I refuse to go any smaller than a 10gal now.

Anyway, this tank has the AQ20 and an airstone. Will this be enough? I kind of baffle the hob so it doesn't actually do a ton of aerating.

How do you guys deal with this issue? I feel like part of my problem is my scape but idk

You can do this: It basically filter media on the waterfall outflow

Perhaps the issue is one of your expectations of what a filter is needed for Fae ?

All the water volume of the tank should pass through the filter around 4 or more times per hour.This achieves the most important job of biological filtration.
A filter is not required to remove solids .(mechanical filtration) If it does pick up a few chunks of poop that is a bonus. The poop will settle somewhere in every tank. Often directly under the filter is the spot poop settles as the lighter water is pulled up . It is our job to remove solids once in a while for cosmetic reasons only. These solids or mulm are not doing any harm, they just look wrong if it’s a crystal clear water with white sand that you/ we desire. While 2 inches of mulm is unsightly it will do no harm . In fact it’s a food source for many of the natural creatures that live in our tanks.

Having dead spots at the front of a tank help us see what needs a clean. Moving the flow from the filter so that the dead spot is out of sight may look nicer?

This is a snapshot of a fry grow out tank. If fry can survive in a tank like this and find natural foods but you/ we don’t what to look at sand this colour it’s our problem not the filter or the fishes problem.
This tank is actually a lot cleaner than last month at the moment as I transition the fry to dry food and am slowly removing their mulm compost heap of Infusorea.( bugs)

I don't think dead spots are going to cause an issue for the betta, they naturally live in bodies of water that have little to no surface agitation.

I use sponge filters, and they create just enough bubbles to disturb the surface of the water. If you find that the filter is too strong, putting some sort of barrier such as a sponge or plastic can help redirect the flow.

I have a hob on my 5 gallon betta tank. I have an intake sponge on the intake, and I also have some of those betta beds under the flow to cushion the outflow of the water. I like the look of those more than using a plastic bottle as a baffel.

Since bettas are air breathers, I really have never worried about the "dead parts" of the tank. I am looking to add an air stone, if I can find an air pump that is actually quiet!

I have a ton of IAL and sometimes add roobios tea, and my little guy is thriving.

Just some thoughts...
