Is 84 too warm? Tanks Running Hot From UV -

[LBDave]

ya it’s the UV for sure

going to trickle cold water to off set the heat -

need to find a device to turn on when temp rises vs turn off - my temp monitors will turn on if get if cold - need something to turn on cold water when gets too hot -

If it was me I wouldn't add complexity as a solution. Complexity can just create another variable that can cause problems to the system. I would simply remove or replace the culprit.
I I am a big believer in K.I.S.S. Just my H.O.

In the rivers of S America where Cichla come from the average water temps are between 78'F-82'F. Temps too much above or below cause stress, which causes immune system breakdown in captive fish.
The problem I have with temps above 82'F are that pathogenic bacteria flourish and become most virulent in higher temps.
Diseases like Columnaris and HLLE are a couple examples of bacteria that prefer those higher temps 82'F and above.
But curious why the overkill in UV.
If you are constantly adding new tank mates, Ior using live feeder fish could see it, but if not, as far as introduction of new diseases or parasites a stabile stock population may not be problematic.
If it is for for constant algae problems maybe.
I never use UV unless, a new pathogen has been introduced, or on a quarantine tank with something suspected, and my tanks are outside open to the elements of constant sunlight, and introduction of parasites from bird droppings is always possible.
if you are feeding live feeders, this would be a reason for constant UV, but even then, UV can only kill what flows and passes thru the light unit, any internal parasites inside a feeder fish (like HLLE bacteria), would not be removed.
I would unplug the UV units one at a time to find if one is out of order, and if one is, you may want to check if its running properly.

Thanks Duanes! very helpful words helpful information on tanks running too warm.

i had a mysterious illness circulating though my tanks - the UV was to eradicate that and provide best possible water quality for my stock -

i need to read more on UV before turning it all off, i’m not feeding live and no new stock will be coming.

i do have overflow drains on sumps so i’ve been dialing in the cold water drip to maintain 80 -

the fish were aggro at higher temps and Leichardti got a little fussy with food -

Thanks all!

Maybe try running the uv on timers rather than all the time.

I highly recommend to turn on UV-C all the time and not periodically.

The reason behind this is that you would allow harmful bacteria and fungus to increase the population. The microbes in the aquarium will double every 20 minutes!
Look at the sketch from Ricardo Castellanos:
Bakterienwachstum = bacteria growth
Bakterien pro 10 ml Aquariumwasser: bacteria per 10 ml aquarium water
Zeit in Stunden = time in hours

Summary: If you only TURN ON the UVC periodically - simply dont use it since it will be not effective + you save electricity.

Cold water drip will cool the tank

Cold water drip will cool the tank

got the heating / cooling dialed in after spending few days home

Thanks all!

Turns out the L2 pumps are heating the water - if i turn them down to 75% it balances the heat issue better, but sadly nitrates creep??
