I am planning to grow riccia, HC, Hair grass, and maybe willow or christmas moss and such.

They stop eating and stay on one spot without moving, usually grouping together. Some shrimps also died instantly! In my experience, shrimp-keepers should not use products like Easy Carbo or Excel.
Only medium to Hi light tanks need fertilisers, and shrimp tanks, IME, do much better with less light (low light 1 w/g). Ferts are not needed in low light planted aquariums with shrimps, weekly wc will add enough macros and micros to the tank.
Also, since tap water in some cities/countries contain little or no macros like PO4, NO3, K and traces (good to get a report form your water supplier) it is good to choose plants wisely.
Small amount of macros/micros in a tap, choose slow to medium growing plants. Tap with lots of PO4 and NO3 + traces should be stocked with a few fast growers.
Folk doesn't understand plant's nutrient uptake rate, and start getting algae problems, and of course start adding lots of ferts to the tank, dosing Excel to kill Black Beard Algae, forgetting that shrimps are living in those tanks.
If the priority is plants, than dose ferts like Excel, but don't keep shrimps in there.
If the priority are shrimps, stop dosing Excel and similar (liquid nor dry), and research you tap's nutritional levels so you can plant according to tap water readings and shrimp stocking level.
Getting BBA, lower your lights (RCS that I found in my Juwel filter box, total darkness, looked healthier than the ones in the tank). BBA comes only if CO2 levels aren't same. Water change will introduce some amount of CO2 which plant start up taking like crazyAfter day or two the tank is at low CO2 again and plants get stressed, and BBA loves these conditions. Low light tanks don't have big problems (or none IME) with BBAlgae after water changes.
For those who are very dedicated and have some time can start performing daily 5% water changes, so adding extra CO2 which comes with tap water, followed by a weekly 20%. No need for Excel in shrimp tanks, just choose low lights (1w/g), get your tap stats and add plants according to tap stats and shrimp stocking levels.
Kind regards, Dusko.

Thanks.
i think easy carbo have nothink to do with gh/kh... my gh is from 1 to 3... and is i said i use easy carbo and excel very careful. i use them because my plants started to turn white and the leafes got holes and gor brown. i use co2 and 3x15W T5 light... after i used easy carbo and excel the plantes started to be very nice again...Dusko wrote:I did some more testing with Easy Carbo (as Excel) in shrimp tanks and got another conclusion!
Glutaraldehyde is not directly effecting shrimps but rather Glutaraldehyde in tanks with low Oxygen levels and low KH/GH.
People I know which have medium to hard tap water have no issues with shrimps and Easy Carbo/Excel. I on the other hand have very soft tap water (3GH/2KH) and have issues as soon I dose Easy Carbo.
Something happens in my soft water tanks when EC is dosed.
Now I dose bicarbonates and GH-Booster keeping the GH at 5 and KH at 4, and no shrimps have any issues. I also have created moderate surface agitation for better gas exchange (more O2).
But I am becoming more cautious when it comes to keeping shrimps and Easy Carbo/Excel dosing. I rather go with CO2 gas (in Hi-light tanks) instead which only makes my Crystal Reds breed like crazy.
In a case of Low-light tanks I go with the Low-tech method using soils as the main plant nutrient and easy to maintain plant (Cryptos, Anubias, Microsorum). Soils also have a very good CEC (Cation Exchange Capacity) keeping nutrients in the substrate which plants can uptake via the root systems.
Thanks for your replies.
Regards, Dusko
it is toxic for shrimps. so never ever use cryptos in shrimp tanks.
I'm not going to weigh in directly on the Flourish use/don't use debate since I don't have enough experience with it. However, just to put numbers in a little bit of perspective, I know many people will put blanched vegetables into shrimp tanks. On a weight basis, cooked spinach has almost double the % of copper as Seachem Flourish. (0.000167% if you want the exact number, based on one scientific analysis. A similar analysis of raw spinach gave a result of 0.000093% copper--roughly the same as Flourish).Suzie Q wrote:A lot of people mention using Flourish and Flourish Excel(?) for plants.

That's also been my experience. *Over*dosing ferts can and does lead to organic buildup over the long run, too. That leads to algae (the floating type...not always visible) and bacterial blooms (also not visible...most of the time), which lead to "mysterious" shrimp deaths. In a tank where the plants always take up all the nutrients, that should not be problem...theoretically. But balancing such a sytem is extremely hard to do. And if you underfertilize...then plants can rot away and increase organic pollution..which again causes bacterial blooms. That's why I just don't have any plants (besides algae/biofilm) in my shrimp tanks. Others may enjoy plants in their tanks along with their shrimp, but then they also have to deal with the difficulties. By the way, just as an sidenote, there are no higher plants in typical shrimp habitats (and most fish habitats for that matter). I have seen many first hand. Shrimp like "clean" water and the nutrient levels in most shrimp habitats do not seem to be sufficient to support higher plant life.Dusko wrote:It is not the Macros or Micros that can harm the shrimps but rather organic build-up, uncycled/new tanks....
Over-dosing is not necessary and should be avoided especially in tanks which aren't heavily planted and in non-CO2 tanks with low-lights (1-2 wpg).*Over*dosing ferts can and does lead to organic buildup over the long run, too.

Sorry mate but I think you ended up in a wrong threadQuestion: Are any of you using Red Cherry Shrimp with plecs? (Which plecs? Please describe how the tank is set up. Thanks..)
