Hello Fellow reefers..

In light of the recent freezing cold temperatures effecting 100+ million people in the U.S. alone, we re facing temperatures that are shattering All-time records across the world... yesterday, Minnesota was colder than the current conditions at the south pole observatory...:eek:;Cold

Why not share and reach out on #r2r and maybe #reefsquad to handle the issues that I came across.. and I thought a solid point of advice and ideas could be focused in one thread. This way everyone can read, learn, and share their own ideas on how to minimize fluctuations in temperature, as well as other less obvious issues that come along with it.


Feel free to suggest and add topics and fixes to this thread. We can always learn more from each other.

Issue: Temperature

Of course. A staple in reefing success is to maintain a stable temperature. Whether u prefer it tropical at 80°f or a chillier 76°, sub-zero temperatures will effect any living thing one way or another in your tank.

Recommendation(s): 2nd Heater

Add a 2nd heater to supplement the demand for operation. This will aid in keeping one heater from working too much, and more importantly can save you if yours malfunctions and you sustain a dangerous temperature drop in your tank.

Issue: Alkalinity swings

As I pondered the idea of temperature, and evaporation increasing, I also realize this continuous addition of fresh RODI water to my tanks volume, It made me think of swings this may cause in parameters. Alk (dKh) being the main focus. Even if your Alk is on a dosing schedule of sorts, or if you have figured out your specific need for Kalkwasser in your ATO(I dont recommend) your consumption and requirements to maintain the numbers you are used to seeing in regards to dKh will change based on evaporation.

Recommendation: Adjust dosing regemint. Add a lid or cover to help with evaporation loss.

In theory, your previous calculations of necessary dosing for dKh would no longer maintain the levels u prefer due to more RODI topoff than previously required. I would suggest to simply increase your dosing quantity very slightly as it gets colder outside and drier in your home.


A humidifier is a huge help to evaporation as well, but for most, they likely dont have one. And thus we make many more trips back to our water stations keeping the ever-disappearing water level stable in our tanks.


Hope it wasnt too much to read, and I'm hoping I see a LOT more tips and tricks for cold winter months to help any new comers or just to teach some old dogs new tricks! I know people who have been reefing for 30yrs and still learn something new on a regular basis!

You can avoid all this by moving south as well! :cool:

Best of luck keeping things healthy around these cold seasons that a lot of us deal with in the north! Thanks for reading! Reef on!
 
Man, I am so glad I no longer live in MN. I always hated those temps. However, growing up there you got used to it. My family are all still there. Poor things.

Tips, extra heaters are a good plan. Also, generators, temperature controllers (in case heater goes wonky). Keep the house a decent temp if possible. Keep up on top off. Mine goes nuts with no humidity in house.
Also, guys a reef can go down in temp pretty good. I had mine running months at 70degrees and everything was happy and growing. (did not realize heater was not working). Just remember to bring it up slowly.
Of course, some animals prefer cold or warm, but most can handle a drop in temp okay.

Stay warm. Give all the animals little blankets.
 
Haha. I thought maybe this thread would take off with the veterans chiming in with ideas and things that work for them. :shrugs:

Stay warm and thirsty my friends!
 
Maybe I'm completely wrong and they just don't wanna school me. LoL

My father was born in St.Paul. said it was horrific in the winter.
 
Why would increased evap change your alk consumption?

I would think if you are diluting your dialed-in tank and dose, be that by diluting the tank more often due to more evap that u may see a different level of required dosing amounts to balance it out.

More of a theory than verified fact. Was kinda hoping to get some more knowledgable people/person to discuss the idea or if I'm completely wrong.

I'm not an expert by any means but when the water evaporates it evaporates nothing but pure water which is replaced with rodi so the net would be no change. Unless you're using kalk then increased evap would raise alk because you're adding more

Wouldnt the dilution created by the rodi reduce the alk as well? Unless u match ur rodi water dkh prior?

So as undosed rodi comes in to the tank at a greater volume more often during winter, wouldnt the alk reduce along with it?
 
Or am I misunderstanding the behavior of alkalinity all together?
 
Not sure on the Alkalinity conundrum.The cooler temperature may influence your Ph,which may influence your Alkalinity.Additionally, I know that topping off with fresh water will raise your calcium slightly. As for keeping your tank warm,it's important to keep in mind that gradual changes in temperature are usually tolerated just fine.

That said, I would suggest standing next to your aquarium first thing in the morning.Before coffee and before you adjust to the temperature yourself.Notice if you feel any drafts from nearby windows or doors.Deal with them accordingly.

I'm pretty sure it's just in and out. Even in the summer if you use a fan to keep temp down it's evaporative cooling so your loosing a lot of water that way. It shouldn't effect alk. Maybe calcium if it's in your RODI water but it should be minimal.
