    Iwagumi Shrimp Tank

    Have been doing research on Walstad, DSM, Iwagumi and RCS tank with Eleocharis belem as foreground (If I can get my hands on them otherwise, acicularis) and I think I'm almost ready for it but would be nice to have some input from pros and shrimp gurus. The plan is little to no maintenance, set and forget type of deal. Will be doing a DSM (my first attempt ever). If DSM is not working out, will switch to submerged using pressurized CO2 and ferts initially. There will be NO ferts, filter, and CO2 once carpet is laid out and cycled.

    Here are the specs:

    15 gal rimless tank with dimensions: 19.75 x 13.5 x 13
    Potting soil capped with Eco complete substrate (had an extra bag lying around)
    This light: https://www.amazon.com/dp/B07236CXBQ...=29BL0ETRWITHO
    Ryuoh stones for hardscape
    Tap has GH and KH of 9 drops, pH 7.4-7.6 (using API test kit)

    I guess the main question is if DHG will thrive without CO2 and ferts once submerged...

    I have a 10g rimless that I did a dry start a few months ago with dwarf hair grass. Its white sand with Osmocote Plus mixed in. Flooded the tank after 3 weeks. I dont do co2 on that tank because it is a shrimp tank. I do dose ferts though. The dwarf hair grass doesnt grow and spread super fast but it is filling in nicely. I had planned on it taking a good 8 months for it to fill in the way I want it though.

    I started with 2 tissue cultures from CK Fish World back at the end of august. I have to do a trim and clean up on the tank and I'll show you some pictures of its progress. FYI for when you see the tank.....white sand doesnt stay white, lol.

    The light is a cheap clip on desk lamp with a 23w 6500k CFL bulb plugged into a timer. I dose ferts once, sometimes twice a week (there is also osmocote in with the sand and root tabs).

    No, you can get by with cheap lighting for small tanks. I use the desk lamps all my small tanks. The timers I use are a $5 timer from Harbor Freight. Its a decent lighting system for cheap.

    I did this on a tank once; it's good for growth but two things to keep in mind.

    1) It's impossible to move anything around in this set-up. I realize you probably only intend to have the carpet, but it still matters because it creates a mess if you cave in and try to put additional DHG after you cap to speed up the process, or if you want to lift up portions of the carpet (say if you want to add new stones or anything)

    2) IME, eco-complete bleeds a lot more tannins than a sand cap. Even a solid 1.5 inch cap had brown water for me. Can easily fix with purigen. I personally went back to sand as a cap after trying this once though.

    I've done a few dirted tanks and have found the least messy way to plant is to plant in just the dirt and then cap it after. Keep a spray bottle to keep everything humid while you work.

    I've seen a few people grow DHG with just eco complete so I'm just gonna go with that along with root tabs... They say shrimps dont mix too well with dirted tanks... I'd rather go with the safer route (~_^)... Thanks for all your 2 cents!

    A "sand cap" is usually used in dirt tanks. You put the dirt on the bottom of the tank and put your aquarium sand on top of it so the soil doesnt mix with and foul up the water.
