Filter for shrimp in co2 injected tank

Hey there, I have a 10g tank to which I will add some cherry shrimp. I tried to aquascape it as good as I could and I also added all kinds of plants, moss, floating plants etc. The thing is that I really need to inject co2 with these plants and the tank has a sponge filter at the moment. I thought it would be best for the shrimp. Sadly the sponge filter doesn't make any water circulation and I believe the co2 is pretty much useless. For now I've added a HOB as well in order to make some circulation. In the future I could just leave the HOB on it's own and maybe add an air stone for some more surface agitation.

Idk if this matters but the light is a Twinstar B 45cm, the substrate is dirted and I'm adding micro, macro and carbo because the plants we're planted about 2 weeks ago and they have no roots.

Also, the tank was dark started for 2 months and then I added the plants.

 

There are only a few plants that really need CO2. Unless you are using the Twinstar B without a dimmer of course, which I can't imagine, as the Twinstar's, without the dimmers, would make my tanks look like lighthouses.

Anyways, ideally, any filter that helps you diffuse and distribute the CO2 would have my vote. Diffusion and distribution of CO2 are just as important as the amount you bring in.

 

Yep, the light is on a dimmer, it's at 60% now. I'm adding the co2 because the plants were grown with co2 and I didn't want to shock them too much.

Strangely enough, the hygrophila polysperma rosanervig is the most shocked out of all of them, and I have both substrate fertilizer and liquid.

 

Most of my tanks have no CO2 injection/supplements, and they all have a Twinstar B at an average of 7%.

In general, plants are grown with CO2. When you bring them home, you simply let them float for a month in water (without CO2 injection/supplements) and then take them completely submersed while keeping lights dim.

Strong lights + low CO2 is cause of trouble. Fertilizer won't change anything to this.

 

I'll dim the lights some more, hope it helps a bit. Right now most of them are alright, the've grown roots, all of them and they've started growing.

I kinda have to start adding shrimp because I'm taking thrm from a friend and I promised him I'll take them as soon as possible

The parameters are good and there are enough plants and moss in the tank.

 

Feel free to share a picture.

 

Sure, I'll get home in an hour. Thanks a lot for the help
Here are some photos. The light isn't that strong, it's just my phone making it brighter.

 

I use a HOB canister on my 20 gallon that has cherry and amano shrimp. And I dont use a predicted on it, haven't had problems as the cherry shrimp keep growing in numbers.

And I use CO2 on low, 5 lb CO2 bottle, lasts for months.

Lighting is Aquarium Coop light at 100% for 10 hrs a day.

It's an easy tank, I just top off water and clean the glass and rise the sponges from canister once a month. Have to trim plants every two weeks, about it. It's heavily stocked with 6 Cory, 7 platty, some sort of algae eaters, 8 amano and who knows how many cherry, prob 20. Root fertilizer once a month, and I only dose iron and phosphorous. The all in one fert is for the goldfish tank to upkeep the carpet algae

Good job on the tank!

What I would do: Get a very small, slim internal filter. Preferably it does have some power (over 5W) and comes with a spray bar or you can add a spray bar.

Ideally, the spray bar runs at the back, across the full length of the tank.

In terms of filter media, anything that avoids shrimplets being sucked in is OK. A coarse sponge should be fine.

The purpose of the filter is water movement and CO2 distribution. Not filtration.

Place a CO2 diffusor straight below the intake of this filter. The CO2 bubbles will be further diffused by the filter and distributed evenly. CO2 rich water shoots to the front and goes down and returns to the back of your tank.

I would run a bubbler at night to keep the water surface clean. If not, a thick biofilm will emerge due to all the organics produced by CO2 happy plants.
