Dino Pee is made up of 50gm SOLUBLE CHELATED TRACE ELEMENT (Fe, Zn, Mn, B, Cu, Mo) 250 gm POTASSIUM SULPHATE (K2SO4) 250 gm MAGNESIUM SULPHATE (MGSO4.7H2O 125 gm POTASSIUM NITRATE (KNO3) 25 ml HYDROCHLORIC ACID (HCl) (optional as preservative) swimming pool strength (350g per litre) 3 litres WATER (demineralised H2O) If the acid is not used, the brew must be kept in the refrigerator. The stock solution is dosed into the water at 10 ml per 1000 litres of aquarium water. - straight from Dave at Aquagreen. It's a pretty good K & P macro fertiliser. Dose is 10ml per 1000 litres. So make sure you have added the correct dose. That's very little required. You could halve the dosage if in doubt for a tank with shrimps. Dino Spit is a ten percent solution of glutardaldehyde. Dosage is 1 drop per 10L of water. Again this is a very low dose. Check you are not over dosing. It's equivalent of Seachem's Flourish Excel. An alternate source of carbon for plants. Both products are low cost alternatives to the expensive imported brands. It is a compromise, either you look after the welfare of the plants or the shrimp. High tech, fast growing plants with shrimp is a bigger compromise than low light plants. So choose low light plants. A shrimp tank can still look beautiful with low light, low demand plants. I know, I have many like that with shrimps in it and minimal fertilisers being used. Not saying you can't succeed with high demand plants, it's just harder. Ferts need to be introduced slowly into the tank if there are shrimps. Of the two ferts above, Dino Pee might be the culprit based on your shrimp's reactions. "Hanging" out on the surface means they are trying to get to more oxygen. And of the two ferts, Dino Pee with it's glutardaldehyde would cause such a reaction in the shrimp. Glut depletes oxygen in the water. If you add a pinch of Bicarb Soda to your water changes, you can raise the KH and pH of the tank. And by doing it every water change, the increase is slow enough to not affect the shrimp. Aim for a pH of 6.6 -6.8 for RCS (they can handle 7.0 just fine, slight acidity is good for the plants). Edit - As for drip container i use a DIY system. Air hose, Cleaned 4 (or 3, cant remember) Litre milk bottle. The soft plastic makes it easy to work with. Cut open the milk bottle at the top to allow you to add water, much like a water can hole. Basically, large enough for you to pour water in. Leave the handle for easy carrying. Make a small hole just a fraction smaller than the air hose at the bottom of the milk bottle and fit int hose into it. Silicon it in for a water tight seal. You might not need silicon if you did it right, should be tight enough. But use silicon if you butchered the hole while making it. At the other end of the hose, attach an air valve. One of these ...

Well, the Bacter AE went well, but for some reason when I looked at the stick of Dennerle Complete I just put into the tank I didn't think it'd be like 20X the amount I've been feeding the shrimp. Oops. About 30 minutes left and I'm vacuuming it up. Annoying for me. Next time, I'll crush it like Simon suggested. Such a large portion makes an awful mess, too.

I have a reply from them on the cost, there is no minimum order. Message me if you are interested, the cost is very reasonable, in fact cheap compare to the cost in Hong Kong, and they send worldwide, I don't want to post on this forum, without there permission.

Weirdly enough I was watching videos on culling the other day and they warned that shrimps that have molted recently will have less colour after a molt and then colour up more. The video obviously was saying that as you can easily cull a shrimp recently molted because it looks like the colour isn't good, but it may be a really colourful shrimp given a few extra days. I have been using the 5 in 1 mix (smashed up and mixed together) for over a year with 100+ shrimps and still have about 75% of it left, though I only use it tuesday and thursday, very sparingly, as I use many different foods to give them variety, and weekends I use, saturday spinach and sunday shrimp lolly! The bacter ae I use the same as the feeding, dip an old shrimp lolly stick (or toothpick or other similar) about 1-2 mm in water then in bacter ae quickly, tap excess off then put it in the tank - I do this twice each time I use it (30L tank) and twice a week. Probably a lot less than they recommend on the packaging. It may seem to be a bit extravagant to use so many food and other packages but I actually think it is silly not to use the right things as most of the products will probably last for years and aren't very expensive anyway......... ie if you alternate 2 foods the food will last twice as long obviously. Hope it all continues to work well with these beautiful blue blue shrimp. Simon
