Hi all. So some background My 10g tank has: Blue Dreams Amanos 1 Cardinia that stowed away in a plant shipment I got 3 Rainbow Paskais 1 Celestial Danio Phoenix Moss Crinum Calamistratum (Onion Plant) Nymphaea Zenkeri (Tiger Lotus) Bolbitis Heudelotii (Creeping Fern) Eleocharis sp. Mini (Mini Dwarf Hairgrass ) Micranthemum (Monte Carlo) A random piece of Subwasstertang algea but i dont want that The overall goal of this tank is to be a shrimp tank with the neos and maybe a species of Caridina once I'm a little more experienced. But I have a hard time keeping the neos alive a friend who owns the LFS ive been buying them at recommended i try buying from a local shrimper because his shrimp might be more well suited to the local water than the shrimp he buys from abroad because he thinks its weird that im having a tough time with Neos. So I did just that when i met up with him he told me co2 might be the issue since it makes the water acidic and makes molting hard and it makes the water parameters more unstable so I stopped using Co2 for the time being and the shrimp look healthy. But the issue is I would like to keep using Co2 for the benefits to the plants and because id like to keep the carpet ive been working on. Current Parameters Temp: 74.5 F/ 23.6 C Ph: Between 6 and 6.4 (im bad at colors) but its yellow (API Test) Kh: 4 drops the chat says 4 degrees 71 PPM Gh: 6 drops the chart says 6 degrees 107 PPM TDS: Waiting on a meter from amazon. Lights are on between 4 PM and 9:30 PM for those who don't do the military time. Bellow are the spectral percentages of light if this helps anyone. Any advice on how and if I should add Co2?

Up for sale is a planted and complete breeding fire red cherry shrimp and fish tank. This complete setup comes with a full pressurized co2 kit (co2 regulator with solenoid, paintball tank, diffuser, and bubble counter), and lots of shrimp goodies (shrimps, shrimp food, and equipment). There are also various rare plants in this setup such as lots of buces, red moss, triangle moss, willow moss, crypt nurii, crypt flamingo, etc. I've had this tank running for a few month and all equipment and products were purchased brand new. Price is $150 for everything, $80 for complete co2 system, or $100 for everything minus co2 system and local pickups in 90680 only. Send pm if interested.

Ok, so I have a ten gallon with various Caridina in it and plants. Running CO2 controlled via a Milwaukee pH controller, so I can keep my pH pretty close to whatever I want. What are the problems with CO2 and Caridina? I have an algae problem and would like to increase my CO2 to get rid of it, but would like to know what people think 1st. How low can I go with my pH? Thanks in advance for any advice. -Tom

Hi everyone, I've got a planted tank with Brightwell sub, CO2 and Blue Bolts. My pH cycles from 6.08 in the morning to 5.78 in the evening. Is this unhealthy? Should I aim for tightening this range? I turn off CO2 at night about an hour before my light turns off and it comes on about the same time as my lights come on. Also, is having a KH of 4-5 necessarily bad for Caradina? I have really clean tap water as I live in the foothills. So far my few tester shrimp seem to be fine, although i see markedly more activity from them in the evening as the pH climbs lower. Thanks in advance for any advise. Here's my tank too. Just cuz I'm proud of it's progress.

Every day my PH swings from 7.3 to 6.7 due to CO2 injection. 8.15am - lights/CO2 ON. Air pump OFF (stops night aeration). PH is 7.2 or 7.3 at this time. 9.15 - 7.0 11.30 - 6.9 12.30 - 6.8 2.00pm - 6.7 2.15pm - lights/CO2 OFF - 6.7 3.30pm - 6.9 3.45pm - lights/CO2 ON 4.30pm - 6.8 5.30pm - 6.8 7.30pm - 6.7 7.45pm - lights/CO2 OFF -> Night aeration on. This blows bubbles into my tank from an airpump. 8.30pm - 6.8 Its a 3 footer community tank, moderate planted. My setup is 11 months old, ADA soil is about 3 inches thick covering 70% of the area. I thought ADA should buffer PH to 6.8. My PH before CO2 is 7.3. I'm not sure if my PH pen needs calibration or its due to blowing bubbles into my tank (night aeration). KH is 3, GH is 6 I keep Cherries, Blue Velvet, CRS/CBS, Tigers. Except for the CBS/CRS, all the shrimps are doing great and have been breeding. For the CBS/CRS, a bit of a mixed success/failure story. They've been in there for about 5 months now. Had a couple of deaths. Added 6 CBS 2 months ago - left one now (failure story). But that one recently got berried (success story). For the CRS - maybe lost a handful, but generally the population only had a slight decline. They look healthy, but so far, none got berried. I finally nailed it down to the PH swings that are affecting the more sensitive shrimps. Is there any truth to this and is there anything I can do to mitigate this factor? I certainly cannot stop the CO2, neither isolate the CRS.

I have an eheim 2211 (classic). I'm trying to figure out the best way to get CO2 dissolved in my water. I hate seeing little bubbles coming out of my outflow and have been experimenting with reactors, but my flow rate doesn't seem to be strong enough to turn the little impellers that supposedly mix the CO2 into the water. I have a pressurized CO2 tank with regulators etc. I noticed I use a pretty popular canister filter, so I thought maybe someone would have found a solution, or have a suggestion for me? Thanks in advance.

I have a birthday coming up and decided I wanted to purchase myself a Co2 sytem. I know very little about them other than you have a tank, regulator, bubble counter and diffuser thats where my knowledge ends. I want a good quality system to run on my 10g to start and add my 7.5g later on, so something big enough for the two tanks. My price range is up to 200$ so quality is important. I will be running this on my shrimp tanks and dont want something cheap that could kill all my shrimp. Suggestions on equipment brands and newbie mistakes when using Co2 is what im looking for. Thanks
