How can I keep the indoor pool warm?

Toad eggs found in swimming pool that was filled with algae, can we keep them, how do we care for them?

• We were draining our blow up pool and it began to rain. The pool was chlorinated and had algaecide in it. However, that was about 10 -14 days ago. It has rained and sat in the sun. It filled up with algae so we were draining it. It started to rain so we left it. It did not drain completely. Last night toads left many strings of eggs in it. I teach first grade and would like to keep some to show to my class. Do you think they are viable? Do you think the chemicals will affect them? There is no shade in our yard, do we need to shade them from the sun? We have been having temperatures over 95 degrees lately. Will this kill them? Any help would be appreciated.

• Answer:

  when I was a kid I used to keep tadpoles in the garden until they became little frogs and hopped away. All it took was a tub full of water and occasionally some fishfood or similar. I wouldn't worry to much about the algicide, as it obviously didn't work so it may have gotten too diluted by the rain. You should provide some shade, however, so that the tadpoles won't get boiled if it gets too hot, if the water gets too hot it will kill them. Not only because of the temperature but also because hot water has a much capacity to dissolve oxygen than colder water. Definintely leave some algae in there as long as they don't take over or start to decompose they will provide oxygen and also places for the tadpoles to hide and food for all kinds of really small critters the tadpoles will like to eat. When the tadpoles start to get legs (front legs in addition to back legs) definitely provide some resting places outside of the water as eventually they will drown in water as they loose their gills. Though for your first grade kids it will be more educational if you get an aquarium and set it up in your classroom and they can watch the process on a daily basis. Use rainwater or let chlorinated water stand for a day or two if you do that. If you type "how to raise tadpoles" into google you will find plenty of sites telling you all you need to know about the subject.
