need urgent help

  • We are currently upgrading MFK. thanks! -neo
I agree about depth, instead of 5", an outside pond would need to be at least 3 to 4 ft deep to maintain any sort of stability, and maintain the fish you mention.

Is this one of the preform ponds from Home Depot, or a similar store?

If so, they are totally inadequate for even the tiniest of fish, for any length of time.
They are only adequate as a water feature with a fountain.
I use them for growing live food for my fish, and can usually pick them up on the road side free, because they are thrown away when people find out of their inability to maintain fish life.
 
Even with the added water you are still going to have big swings in your water temps. If you are going to keep the fish ouside and control the temps, you need to consider insulating the sides of the pool and get some kind of cover for the top. How big of a pool is it? abover ground pools genarally are thousands of gallons, and even if you are only filling it up a 1/4 of the way, 2 aquarium heaters are just not going to make a difference. As stated earlier, the tropical fish need constant temps and will suffer the same fate as your ID Shark if you can't stabilize the water temperature.

Ok i will cover the entire pond. By the way, what if i place a another 300 watt heater?.There is currently 500 gallons of water in my pond.
Where are you located? How cold does it get at night? If you use all 3 heaters that could work. Do you have any water flow (jets, pump)?
 
i live in riyadth saudi arabia. it gets 18 degrees celsius at night, i have a diy bucket filter.
18 degrees celsius at night is harmful to the mentioned fish species!You need 22,23 or 24 degrees celsius as minimum temperature for that fishes.
