I have my tank near an air conditioner and when the temp starts to rise i switch it on. You could also have a fan blowing on the tank or there are fans you could put on the top of your tank and have the air blowing on the waters surface. I dont know much about these. Ive never had one. My temp in my house dont fluctuate that much. You may be able to get a small chiller. Im sorry i couldnt be more help there.
As for the hatcheries i have tried an upside down 2 liter bottle, a gallon jug and a quart jar. My fav and one that i used everyday is a quart jar. All you have to do for that one is put 1.015 salt water in it, put the eggs in it and put an air line down to the bottom and put a clothes pin on the line and jar to keep it in place. U have to make sure that whatever hatcher you use it has to keep almost all the eggs moving or in suspension in the water. You can also google brine shrimp hatchers or just dwarf seahorses and youll get info on how to make diff hatchers but most just say about the 2 liter bottle. If you want to use a bottle the cut the bottom off, make a small hole in the middle of the cap enough for an airline to squeeze in (dont use and air stone on any of these) and you can either use the bottome that was cut off as a stand to hold the main bottle up or just hang it up somewhere warm. I think they need higher temps like 75-85. And its not nessasary to have a light on them. You can also buy hatchers on the internet or at some pet stores. But im cheaper and decided to make my own.
I had to make an adjustment to my brine shrimp net because they kept going through it. I took a white hankerchef and put it down inside the net and it works. They cant go through it. I used it for brine shrimp eggs and after they hatch. They hatch in 24 hours.
The decapping process is quite simple. You have to rehydrate the eggs first. Thre are many many ways to go about doing it so just find something that is simple and easiest for you. They way i do it is i put about an inch of freshwater in a quart jar and leave them soak for at least an hour (overnight is fine to) then dump plain bleach about an inch or hlf an inch in with them and occasionally swish them around. Usually it will take about 7mins. But i dont go by time. I wait until all the eggs turn orange. They will start off at a dark brown then turn gray then white and then finally orange. Then i dump everything into the modified net and rinse with cool fresh water until i no longer smell bleach. Then i turn the net upside down in my hatcher jar and pour saltwater through it until all the eggs are off and until the jar is almost full then drop the air line in and let it set for at least 24 hrs.
If i have extra decapped brine shrimp eggs i put them in a small bowl, have the salinity is 1.015 and put them in the refrigerator. They stay good for about a week.
Well, I don't know what decapped even really means...but I definitely will get already decapped brine shrimp for certain. How do you know how much BBS to hatch each day, and what do you do with what the horses don't eat?
