Pls help, my tank won’t stay warm!

help! Got home today to find my tank temp at 71–73. Should be 78.
I switched my fish to the new 26 gallon flatbacks that’s acrylic from a glass 20 gallon long. Didn’t realize that new led lights weren’t as warm as fluorescents.
Anyway I turned heater up hours ago and it only has gone up to 74–75.
How can I fix this

the heater isn’t warm enough it’s an aqueon 50 watts not preset. So now what can I do until tomorrow? I have 6 golden panda Corys and 5 panda Corys and 2 pepper Corys and 1 kribnesis. The krib has been hiding in a log all day not coming out to eat so I’m worried he will die of the cold. Do I put a bottle of very hot water in to float? I can’t make it warmer unless I put heater on 88 which is scary to leave overnight in case it overheats but am scared they will die!

 

Mollies shimmying is often a problem caused by insufficient electrolytes. I had a Molly shimmying a week or two ago and I added a tiny ammount of salt ( just 20 gallon in a 120 G tank ) , the shimmying ceased within half an hour and it hasn't done it since. I'm not sure whether Cory's can tolerate much salt, I know some catfish don't like it but I'm not talking about adding a lot of salt, just a tiny bit.

sorry what is 20 gallon what amount? I’m sorry

 

20 grams in a 120 Gallon aquarium.
If you don't have scales to measure it 20 grams is about 3 teaspoons.
I use API aquarium salt but any aquarium salt will do. Do not use kitchen salt that has iodine in it

I think sea salt is iodine free and I have a lot of rhat. Does anybody know if it’s ok for Corys! And Kribnesis Cichlids!

Be careful when dosing salt. Salt is salt, but the type and grain size is going to result in different concentrations. I agree not to use salt with any additives.

I wanted to dial in my brine shrimp hatches so I bought a salinity meter. I used API Aquarium Salt, and in my DIY hatcher (about 1.5 liters) two tablespoons produced the correct reading, I believe it was 1.023, whatever that means. I ran out of API and had some Fritz laying around. I tested it and it was three tablespoons to achieve the same reading.

I'd recommend anyone using salt should get a salinity meter.

 

I'm so confused. Did questions get mixed up?

 

Ha ha ha..what you guy are doing? The question is

To answer this : just set your heater at 78.It take time to warm your tank up..Your fish is ok with 74-75*f ..they will not die or weak..Stop feeding them tonight as water tank is still cool..They might not like to eat and food will be there cloudy water..Every thing is ok ..your fish are safe with that much of temp...

 

Ok I don’t think she is shimmying bc she

I'm so confused. Did questions get mixed up?

no I’m sorry. I know that it’s not good to start diff threads at once so I edited my original thread topic and question. My original thread was asking about shimmies. When I saw that my fish didn’t seem to have clamped fins anymore I wasn’t worried about shimmies but was still worried about low temps and how to raise it (and If it is killing the Kribensis who won’t come out for food and if the molly that hangs out near heater could be getting ich). I know that when a new thread is started it will show up at top of people’s feeds, but a new POST on an old thread won’t show. So I figured my questions about heating tanks wouldn’t be seen bc they were under an old thread about shimmies so I edited the thread name and question so at least it will show up in feeds as questions about how to heat tanks.
Basically I am super worried about it and the fish and so I didn’t want to hope people stumbled across the heating question so I changed the thread name etc etc. I apologize and I won’t do it again I am just very worried.

 

Oh My holy molly....The op mix it up and changing ....lol

 

You should keep a spare heater on hand just in case something happens to one of your heaters

 

Thank you! I do know the heater can take up to 24 hours to register a higher temp. However the heater was set to 78 the entire time when it got low (either from led lights or new tank or new room). it’s a 50 watt submersible aqueon that isn’t preset. What’s odd is the instructions in the box say it works better vertically but aqueon online says horizontal better. Anyway it worked for my glass and fluorescent 20 gallon long but I’m thinking I need to get at least a 75 watts maybe 100. What is the best kind? I have heard EhaI'm or whatever it’s called but amazon reviews weren’t great. Aqueon was good BUT it’s so hard to know what you’re setting bc it is only marked in 10 degree increments.
Any suggestions?

 

100 watts heater good for 20- 26 gal tank .It take time to increase temp any way.It alway on off and slowly increase to prevent fire or burst glass.Heater set on vertical better to even the heat,just put it in middle of the side tank then it is ok.I use the cheap one 7$ so idk what is good brandname..My is still work but you got to know how to twist it if it has water leak or complaint to get replace a new one .You should make a new thread or do the search here in forum to find out what is good and reliable brandname for heater

I'm not a moderator, but please don't do that again. Either start a new discussion, or ask a new question as a reply to an old one.

 

I like Aqueon Pro heaters ..All I use ..
I don't use salt at all and it not good for cories or kribs ..
It is not really good for any freshwater fish but the two you asked about it is a problem for often ..They are soft water fish .
Salt is just an irritant and no name way to raise TDS [ make water harder ] ..Not the proper way though ..Things like Calcium and Magnesium and baking powder should be used to balance electrolytes … If you don't know how to mix those you should not use salt either as it would seem you are just following the someone else said it philosophy that has stunted the fish industry since the advent of the net ..
There is a difference between info and correct info ..Shame the net does not recognize the diff?
I am all against salt in freshwater tanks .

 

Also if i'm not mistaken Panda Corys prefer a cooler temp in the lower 70's and kribs can do fine around 75

So happy I didn’t do it! TY!

Do you think I need a new and higher watt heater then? Or can I keep this one? The hanging thermometer is inside the tank not too far from the heater but I believe it’s correct it’s very new.

 

I use 50 watt heaters in my 5 and 10 gallon tanks and my fish room is warm.
I would look to 100-150 watt for your 26 .
They are made to warm X amount of water X degrees over room temperature ..The room temp matters ..
You want 100 if you don't need to be more then 10f higher then room temp .If you need more then 10f then go 150 watt.

 

Cichlidude he has a good chart to measure what wattage heater is good for what size tanks. I would always go bigger incase you have to try heat treatment for ick when they say to raise the tank temp to 84-86 to speed up its lifecycle.

 

Here is the table to help with what size individual heater you need. Delta T is the difference from the lowest ambient room temperature in the room to your desired tank temperature. Always get a heater larger than you think you need so just round up to the next nearest size.

 

Thank You! And yes prior to the move the heater was directly nect to the filter intake valve and now it’s quite far away so perhaps that is changing things as well. So 150 W! Awesome TY!!!!!

 

I think you should set 74-75 for your community tank.That is ok temp for all the fishes .Do the search about lowest and highest temp each kind of fish can handle and set it at temp which good for all ,not just for one fish and every fish are happy.
