Post ShrimpZoo's 30gal CRS/CBS/Golden Breeding Tank

================================================== ===============================================

Like the title says, I'm going to start a 30gal CRS breeding tank and I'm going to start designing it tomorrow.

I've got 2 bags of "NETLEA Crystal Shrimp Soil (9L)" that will be delivered to my house, so that means the fun official starts tomorrow.

I've already got a basic layout planned in my brain and here is what I'm thinking:

Blue Area: Will be where I'll have my "Breeding Tubes". They will be "Breeding Tubes" that will consist of Cholla Wood. I've ordered 5 sets from NeoShrimp and you can see them at -

I'll be attaching some Java Ferns on top of them as a roof lol .

Red Area: This will be where I'll be placing my driftwood (re-using the one in my current tank). You can check out the piece using the link in my forum signature. I will be wrapping a ton of Java Moss around this piece of wood.

Pink Scribble: That will be where I'll have a feeding dish. The feeding dish is just a simple sushi soy dish holder.

Green Boxes (2): Will be where I place 2 separate filters. They will most likely be Seapora Sponge Filters -

They'll be run by a Marina Air Pump that has a duo air output line:

Random Yellow Markings: Marimo Balls


That's all for the layout of the tank. What I want feedback on is the following (but feel free to comment on my set up) FEEL FREE TO SKIM THROUGH (I blab a LOT):

#1. Filtration - Is having 2 giant sponge filters crazy? or practical? Will there be an issue with flow/current for the CRS? I want to keep water clean but I don't want to create a problem doing so. Because as I've heard countless times, keeping it simple is best and I hope I'm not overdoing it.

#2. Substrate will lose its buffering capabilities after 12 months from what I've read @

How do you guys efficiently+effectively change your substrate? This is something I'm going to have to do in the future so I'm curious to how it is done. Do you just scoop up all your shrimp and dump the substrate and put in a new one? and does that mean you have to re-cycle the tank?

#3. Since this is a breeding tank and I want to keep nitrates as low as possible, would having duckweed as a floater be a smart move? My only plants will be (excluding duckweed) are:

- Marimo Ball / Java Moss / Java Fern

#4. MTS, yes or no. The only reason why I would WANT them in there is because they mix around the substrate and will act as a clean up crew if food gets into the substrate where the shrimp cannot reach it. Is there ANY negatives other than disliking them (some people just hate em because they are ugly)? Besides, won't they help speed up the tank's cycling process?

p.s: planning on having the substrate about 3" in depth (should be fine I'm assuming)

#5. Water water water, is the main reason that CRS keepers use RO water because if they use tapwater for a WC it'll cause a shift in paramaters and shock the CRS to death? IF so, I will be safe using tap water to aqua-scape I'm assuming. I fail to see why I would fill 30 gallons with RO water if I'm not going to stock up with CRS anytime soon lol. So if it is just an issue with parameters then I should be safe (: please confirm if my assumption is correct. I will probably get RO water from Loblaws or Home Depot or even install one in the basement sink while the tank is cycling.

#6. Here is a list of the food I currently have, are they good enough for CRS (diet-wise)?

- TetraVeggie Algae Wafers Xtreme
Crude Protein (min.) 30.0%, Crude Fat (min.) 6.0%, Crude Fiber (min.) 5.0%, Moisture (max.) 9.0%, Phosphorus (min.) 0.8%, Ascorbic Acid (Vitamin C) (min.) 100 mg/kg.

- Hikari Algae WAfers
Crude Protein Crude Fat Crude Fiber Moisture Crude Ash Phosphorus min. 33% min. 4.0% max. 3.0% max. 10% max. 17% min. 0.8%
- Indian Almond Leaves + Blanched Cucumber ( N/A Analysis)

- Hikari Micro Pellets
Crude Protein Crude Fat Crude Fiber Moisture Crude Ash min. 42% min. 4% max. 3% max. 10% max. 12%
- Hikari Shrimp Cuisine
Crude Protein Crude Fat Crude Fiber Moisture Crude Ash Phosphorus min. 35% min. 9.0% max. 6.0% max. 10% max. 14% min.0.8%
- Fluval Shrimp Granules

Crude Protein 37% min
Crude Fat 5% min
Crude Fiber 4% max
Moisture 8% max
Ash 10% max
Calcium 1.8% min
Phosphorus 1% min
Iodine 0.0065% min
Vitamin A 10,000 IU/lb min
Ascorbic Acid
(Vitamin C) 350 mg/lb min
Vitamin E 50 IU/lb min

My plan is feeding them once every other day.

#7. I'm planning on starting off with 10-15 CRS. Is that a good number to start a breeding tank or would you recommend more?

I suppose that's most of what I wanted to say lol... believe it or not this isn't all that I have on my mind atm. I guess having a new tank and getting my substrate tomorrow is making me too excited.

Anyways, thanks for reading and any feedback is appreciated as always.
