Starting a journal on my 40 gallon breeder farm tank. I originally threw together a 20 gallon farm tank to hold cuttings from my first scape but found I was quickly running out of space for new plants and a quickly growing population of Neocaridina shrimp, not to mention, the tank had become overwhelmed with bladder snails (yes, I know they can be beneficial). I had plenty of space for the plants I already had but wanted more for future plants for upcoming scapes. I planned to also use the tank as a temp home for fish. The new tank completed cycling about 7/20/25 and I began transferring the following week. Setup details are as follows:
Tank: Imagitarium 40 Gallon Breeder (half-off Petco special)
Filter: Oase Biomaster Thermo 350 (Only because it was sitting unused at the time)
Light: Week Aqua M900
CO2: Yes, inline diffuser
Skimmer: Oase Crystalskim 350
Substrate: ADA Amazonia 2

I purchased a used tank around the beginning of March that was fully scaped with a few fish and shrimp. I tore down the scape and moved the shrimp to the 20 gallon farm. I thought all I had were a few Amanos which I moved to my main display tank and about 7 Yellow Golden Back Neocaridina. The yellows quickly began breeding but I ended up with a lot of wild offspring so one of the original must not have been a yellow. I now have about 100 shrimp but really don't want to use them in an aquascape as mixed wild, so I will start to rehome them to keep the population in check. I've also moved Painted Platys from my display scape to the farm, as they were breeding as much as bladder snails. There are about 15 in the farm tank now and 2 still in the display tank (I think they're both female). I'll be rehoming the Platys as well. I have no interest in being a fish breeder so no more Livebearers for me.

I wasn't sure about wasting space in the farm tank with hardscape but went ahead and put in a few pieces for now. I figured I could use it for epiphytes and hiding places for livestock. Eventually, I'll probably install some 3D printed grates for the epiphytes. Things are a little disorganized to start. I welcome ideas on farm tank organization.

Great looking farm tank! Looks like a display tank, honestly.

My experience with farm tanks is to consider what your objective is. Some people simply use it as a way to grow other plants. Some as just another display tank. Some for growing out particular species they want to ultimately move to the display tank. Finally, some use them to grow plants to sell and cover the expenses of the hobby.

What's your goal with this tank?

I only intend for this to be a tank for growing plants for my own use and I may share cuttings with others but don't have plans to sell anything. This tank will stay in the work side of the basement.
 
Put the new RO storage tank and plumbing through it's first real world test today and WOW! I wish I had done this from the start instead of spending time and money on my DIY water change cart.

I used my Sicce Ultra Zero to pull water out and dump in a Brute trash can mounted on a Brute dolly, then filled the tank back up with the hose I have running to a shut-off valve I installed in the laundry closet. Faster, more efficient, and less mess than any water change before.

Also took what I learned from @Dennis Wong's postings/teachings and uprooted a bunch of Rotala Orange Juice after trimming, replanted the cuttings, and added some fresh root tabs.

That’s a nice list, many that I would like to try myself.
 
I've been busy lately so the Farm Tank has been just a little neglected and left to do it's thing. Photo is after trimming a couple plants but more maintenance is needed. Plan to devote significant time to it over the next few days. Gotta say though, plants are thriving. The Ludwigia inclinata Meta I recently got from @Burr740 really took off. It's one I had to trim and replant today. At this rate, I'm going to need another 40 breeder soon. 😄

Farm tank is a little bushy and disorganized, but it's serving its purpose of providing plants for the other tanks. Most if not all of the Monte Carlo will soon be getting used on the new 25 gallon Brazilian scape and 1 or 2 of the other plants may be going there as well. About to do a big reset on my Waterbox 3620 and will be using much of the Ludwigia Super Red and Rotala OJ there. Just pulled out most of the Dwarf Sag to use as an easier plant for the UNC30 nano tank. Neocaridina and Painted Platies are still breeding like crazy. The Platies blend in well in this photo so its hard to tell there are over 30. Will have to find new homes for the them soon.

A little update. I clearly don't put much effort into my farm tank. I do keep up with water changes every week but I go too long between trimmings and just stuff plants anywhere I can fit them. I did recently rehome about 25 platies that I had moved here from my main display tank upstairs. There are still 2 in here that evaded capture but I think both are females. There's also still a large colony of Neocaradina, mostly yellow golden back but I also had a good number of Black Rose which I've been gradually moving to the main display tank.

The days, though, are numbered for this tank. A few of the plants will soon be moving to my 25 gallon Brazilian tank and the most others will eventually be moved to a new 60 gallon breeder tank. I hope to set that tank up more as a practice Dutch style tank or at least hybrid Dutch style. Thank you to all here for sharing your knowledge and inspiration. We'll see if I've learned anything from you. A few remaining plants will find homes in other upcoming builds.

I don't think I'll ever need to purchase anymore Monte Carlo. 😁
