Temperature swing from day to night

[SaltyGroves]

During the day I keep the AC at 80 and at night it's on about 72 sometimes lower when my wife messes with it. Any ways I notice my tank gets real warm during the day. Everything looks fine except I do have some super pesky brown hairy algae taking hold( hope not Dino's). Got a clean up crew on order because mines slim.

What do you guys think about the temperature swings?

Naturally thats on the high side but not OMG(assuming your keeping all tropical species)...and the ocean temps are going to swing day to night too.

I try to keep mine around the 77..

and Nice mangroves!

What is the temp swing?

83 is fine.. I run my tank at 84 year round though it is a bit risky because if some equipment does fail the tank will get to 90 quicker which is the point where coral will really start dying. My tank has spiked to 86 a few times and been perfectly fine.

As far as your tank 78-83 is absolutely perfect temperature range.. Wouldnt be worried at all.

Ok thanks for the input fellas. [emoji1360]

I figured a 4 degree variance from day time to night was worth discussing.


But My mangroves are doing fairly well. At this point some better than others. Like the one all the way to the left that has NO leaves I pulled while another has kept all its leaves and even grown another. Luck of the draw I suppose [emoji88]

I am a bit troubled by this brown stuff. Starting to really take hold.

It all happened when I made the mistake of getting a mandarin. I took some terrible advice and got a mandarin and seeded my tank with like 4 bags of pods and tried to get the mandarin to eat cyclopedes mixed with live brine(which he ate) and also Mysis(which he tried) and a host of other foods. Long story short I had him for a few days and have since given him back from whence he came[emoji88][emoji263].. But the bloom came after and I'm working on reducing nutrients at this point [emoji35]

so you way over feed the tank............thats not a temp issue...

 

[SaltyGroves]

I did for a time. Yea the temps been like that ever since I started trying to cut the electric bill down.

I'm back feeding pretty sparingly now. Hopefully it all evens out. And of course water change once a week.

When you overfeed the aftermath takes a while to resolve. The phosphates from that food leach into the sand and live rock and then linger there pretty much until algae or bacteria consumes it. So you might have algae for a while even while you are not feeding the tank. But soon as the algae dies off the nutrients will be exported into your mangroves and your tank while be beautiful again.
