Dosing Fertilizers with Shrimp

 

 

 

 

By Ryan Wood

One of the most common questions regarding shrimp keeping is whether or not dosing fertilizers is safe for shrimp. It is a heavily debated topic and there seems to be no definitive answer. Some people believe it is safe, while others do not. Therefore the only answer I can offer is my opinion and experience with this topic. I am sure some may disagree with my opinion. However, the only true way to get the answer is to experience it yourself and decide whether or not fertilizers are safe with shrimp in your tank. No tank is the same regardless of size, plants, substrate, etc.


Before determining whether fertilizers are ok please note: Regardless of what you are dosing, make sure you read the labels and are not overdosing your tank. If you overdose you could be harming your shrimp regardless of what you are actually dosing. Before you want to blame dead shrimp on fertilizers, account for how much you are dosing. The Estimative Index as well as other different dosing regimens recommend dosing slightly more than normal, due to the fact that you change a lot of water every week. If you follow these dosing regimens make sure you are not going overboard and also make sure that you are changing your water as according to plan. There are also methods of calculating how much ferts are being consumed by your plants by testing the amounts and using calculators. You can find this information and other dosing methods on many freshwater planted tank forums.


Disclaimer: This is simply my experience with fertilizers and shrimp. Therefore it is my opinion, meaning that this is not a golden rule. Use this information as you wish, but please do not make it the common law. This subject is dependent on so many different scenarios, parameters, regimens, etc. that it is almost impossible to get a definitive answer.


I have kept shrimp for a while in both fertilized tanks, and non-fertilized tanks. One of my tanks was heavily planted 10 gallon with demanding plants. The lighting needed to be high, lots of CO2, and an ample amount of fertilizers. In this tank I kept the plants Ammannia gracilis, Rotala wallichii, Limnophila aromatica, and a few others that in order to thrive and look their best required detailed care. I kept Red Cherry Shrimp in this same tank. I dosed Greg Watson fertilizers, which are dry fertilizers allowing me to dose specific amounts as well as not spend so much on fertilizers. I also dosed Kent Pro-Plant out of the bottle. Please visit My 10 Gallon Planted Tank Journal for more information on my 10 Gallon Tank. (I have not updated that journal in a while because I have been too busy with shrimp breeding, sorry).


In the beginning I dosed KH2PO4 (Phosphate), KNO3 (Nitrate), Plantex CSM+B (Trace Elements), Seachem Iron and Kent-Pro Plant. Plantex CSM+B also contains some iron, but in order to bring out the nice red in the plants I needed to dose additional Iron by itself. When I added my Red Cherry Shrimp I continued to dose the same fertilizers. At first I noticed that the shrimp were not that active, and they tended to hide a lot. I figured that since there had not been any shrimp in the tank before, they were gorging on uneaten algae and detritus. However, after about a month I noticed that their colors were not as vibrant as they should have been, and also very few females were becoming pregnant. Their numbers also started dwindling until I could barely find any. I would occasionally find dead ones. At feeding time very few came out to eat, so I figured they were probably eating the dead ones. In other words, they were not healthy.


I began asking around several of the forums about why the shrimp were behaving this way. I stated that I was dosing a lot of fertilizers including CSM+B. CSM+B contains copper, which is said to be harmful to shrimp. A lot of people recommended that I stop dosing CSM+B due to the copper content, so I did. I changed the water in the tank and begun to only dose KH2PO4, KNO3, and Kent Pro-Plant. After about a week of stopping the CSM+B I noticed a major change in the shrimp behavior. They were eating a lot, and coming out more often. I purchased more Red Cherry Shrimp and added them to the tank. The new shrimp did well and several females became pregnant. I also observed the plants closely too. After a while I noticed that the plants did not seem to be affected at all after stopping the CSM+B dosing. They still blossomed and looked great. I was happy to see both of these positive reactions to the stoppage.


I decided to do some more research on the fertilizer & shrimp topic and also read that excessive Nitrate is a potentially harmful substance to shrimp as well. I decided to stop dosing the KNO3 (Nitrate) and see what happened. My theory about stopping the Nitrate was simple: I figured that the shrimp feces would produce enough Nitrate for the plants, so therefore dosing additional Nitrate would only harm the shrimp and not have any positive effect on the plants had I not dosed additional Nitrate at all. My theory seemed to be correct. After a while of not dosing any KNO3 I noticed that the shrimp were even healthier, gaining better coloration, and the plants once again seemed unaffected. I never dosed KNO3 since, and the plants have done very well without any negative effects. The shrimp also became extremely active and would literally fight during feeding time.


So, I stopped the Plantex CSM+B, as well as the KNO3, and the plants were unaffected. More importantly, the shrimp seemed to be doing much better. There was a much noticed difference in shrimp activity and health between dosing these two fertilizers, and not dosing them. The only remaining fertilizers that I was dosing were the KH2PO4 (Phosphate), Seachem Iron and Kent Pro-Plant. Please note that the KH2PO4 also contains potassium, which I feel is harmless to shrimp. Some feel that Iron may also be unhealthy for shrimp, but I do not feel so at all. I still dosed A LOT of iron in my tank once I stopped the CSM+B and KNO3, and the shrimp did not seem to continue their unhealthy ways.


Remember that a lot of different types of fertilizers are out there, mostly in bottles by different manufacturers. However, the basic elements are the same as with what I was dosing: Potassium, Phosphate, Nitrate, Iron and Trace Elements. Read the labels on what you are dosing/buying before you decide to dose.

Remember that this experience is based on a 10 gallon tank, very little water volume. If you are maintaining a 55 gallon tank then things are definitely different. Your plants will need more fertilizers due to the increased water volume, and increased plant mass/growth. So depending on KNO3 to come from shrimp feces only may not be a good idea for a larger tank. Also, dosing CSM+B may not be a bad thing either for the same water volume and plant mass/growth scenario. If it were up to me though, I would dose very little KNO3 compared to what would be recommended, and I would dose even less CSM+B. Your shrimp will be much more sensitive to difference in amount of fertilizers than your plants will. Sacrificing a small difference in plant nutrition versus shrimp health is more important if you want healthy shrimp in my opinion.

 

Addendum: A lot of hobbyist's have asked for my opinion on Flourish Excel in an invert tank as either an additional supplement to CO2 or a replacement. I have used Excel in shrimp tanks before and have found that the shrimp seem to act better when I did not use it versus when I did. Once again, this is my experience and opinion. Some will say that Excel is perfectly fine. Put it this way: I will never use Excel in a shrimp-only tank. Use moss or ferns instead of CO2 demanding plants in a shrimp-only tank. Moss is great as it is virtually no maintenance, provides cover for the shrimp, provides food for hatchlings, and many other benefits. If you are putting shrimp in a tank with demanding plants then use either pressurized CO2 or DIY CO2, providing the amounts required for the plants. Nothing wrong with natural CO2 as long as it is not dosed in excess.
