Temperature for Koi and Pl*cos

[hineigger]

Hi.

I know this belongs in ponds but its a more general question..

I have a 250g indoor pond with 3 beautiful koi and 2 comet goldfish that were used to cycle/test the tank, but have stuck around...

Anyways, the water here in Arizona contains alot of phosphates or something like it, and every time water is added to the pond alot of brown algae shows up.

I purchased 2 trinidad pl*cos today and put them in. They look identical to regular pl*cos, and Ive had one before and it grew as large etc etc. So its alot like normal pl*cos... They are eating up all the algae very quickly!

Anyways, what temperature should the pond be at? I currently hve it at 75f stable... Is this to hot for the koi? To cold for the pl*cos? Im imagining not, but, is there a better temp for it to be set at?

Also, various plants in the pond, all doing great and growing. Just wanted to throw that in in case temp affects the plants...

its fine but you can lower it to 72 or 70 kois like the cooler waters and the plecos will still be ok.

PLEASE...it's "Pleco".

...despite the myth that your poor plecies will all die if you call them by the proper name (some nerd probably made that up), I have had great luck with them for 17 years now. ;)
