Set up at 78 for 2 hours in 68 deg. room, in Fluval 5, in pump space. Temp has only gone up two degrees. Is this normal? Seems slow to heat.

You're asking a lot out of that little heater. It's a general rule that heaters can only raise the water temp 10 degrees above the room temp. You're at the very edge of the threshold, so I'm not surprised it's taking a while. Give it time.

I am unsure about heating a Fluval 5 with this heater. I had no problem with the same scenario (set up heater at 78 degree in a 68 degree room), however I have a Fluval Spec 2.5 gallon tank.

The reason your temp isn't going up in the tank is because there is no water movement in the pump chamber. The only way to remedy this is to punch small holes in the plastic tubing which runs from the pump to the outlet. This will get the water flowing inside the small chamber where you are keeping the heater.

I had a similar issue just the other day. It seemed the water temp wasn't moving. I unplugged it, let the heater sit (in the water) unplugged for about 20 minutes. Then plug it in again. I think the heater needs time to get acclimated to the water temp, before the filament or whatever starts cooking. Give that shot before you start slamming the heater against the wall. = )

It keeps my 150 gallon pond a warm 75 degrees, but it fluctuates. It is made for an aquarium, so I would guess it will take a while, but it will warm a 250 gallon tank...though it may fluctuate some. Mine fluctuates about 10 degrees (5 up, 5 down), keep in mind mine is outdoors and the outside temps fluctuate too. ;)P.S. I am very happy with my purchase!

i got a simple small tank heater, in which you can place underneath the thanks. Keep temp at 78

I've been running it in a 65 gal marine talk with a 10 gal refugium. I placed in the sump area of the refugium. It worked fine for me in a building that is climate controlled around 74-75 degrees. I found mine to be miscalibrated around 2.5 degrees, though, so you may want to consider an alternate thermometer if you have sensitive stock.

I just ran a cup of water through into an open cup and tested it with 3 different candy/meat thermometers. I got 166, 168 and 175. It might be hotter with the thermal cup though. It sounds like it doesn't meet your target temp.

I just bought this and I have a 18 foot round above ground... I raised my temp 10 degrees in about 6 hours at initial start up. yesterday I had it at 82 degrees and turned it off over nite and came home next day from work and temp dropped to 70 degrees and I got it back up in a few hours. I live in Cleveland ohio and keep a solar cove on the pool to conserve the heat...it really matters how many gallons u have. call Hayward the got reallt good techs to answer ur questions,,,this pump was a steal for 1715.00 bucks

It took mine under 15 minutes to heat my 2.6 gallon tank from 74 to 78 degrees. If I may, I would suggest that you check out a 50 watt heater, the 25 w is meant for 2 to 4 gallon tanks.

I have a 225 gallon tank and I run two 150 watt one on each side and my temp. Stay. At 76

I have a couple of these in some 10 gallons. Make sure your heater and thermometer are not too close. When the heater coils turn on they make the surrounding water rather warm. You may have experienced a 80 reading when the pilot light was on and coils were hot.

Don't use a timer. Your plants will dry out and die. The pump that comes with it is a lot larger that i would have expected. Placed the unit in a 77 degree room. The water temp rose to between 78-80 the next day, acceptable. If you are worried about the water temp, you can buy a smaller pump, only about $15, and that should keep the water a little cooler. Also, keep the water level just below the jets, that will elp keep the temp down. Good product.

I currently use a heat lamp in mine and my chicks are doing fine and it has been below zero here. It is a small coop smaller than it appears though but for that reason I think that is why it is warmer .

My pool is spprox 30k gal. Will raise temp from 80-90 degrees in about 8 hrs.

Our temp is also 45, it takes a little longer for it to come up to 180, about 2-3 minutes. We use it in the bar restaurant with no problem, also have one in shower room, just be sure to use free flow head or it will run cold.

Sounds like you used too much safe start, only a 1/2 teaspoon per 2 gallons.. Dont rush it. For me, with a pump running, at least 7 days. Buy only 1 fish to test, watch the fish for a day. Add fish 1 or 2 at a time and see that they are healty..good luck

The temp situation has been frustrating b/c it says it can be set at a certain temp but when trying to program it to stay put, it simply rises as your liquid inside is mixed, I use it for liposomal Vit c. I have found that the temp simply reflects the temp of the outside container, not your mixture so I have adapted and keep my thermometer handy and take temp of the liquid then add ice as it mixes to keep it below 104F. Its truly a great machine and for my purposes has worked fantastic other than the minor temp issue. Now that I realize what i need to do, its no problem. The lowest temp I have seen is in the 70's F and if I run it at 5 min intervals and let it cool, I can keep it well below 90F. Good luck. MS

I have a 13000 gal in ground pool and it increased temp approx 2 degrees per hour .

Just set mine up: checked all the moveable parts to see that they were in place, filled it with cool tap water to the "Max" line (as instructed for first time use), and turned it on to check all speeds and modes. Remember to turn on the "cooling/humidify" button (the light will come on) The air is cool, like the air coming off the ocean-not cold like AC air flow. (I notice a faint chlorine smell with first use.)
