the heater and filter saga continues! my eheim jager heater and tetra whisper in tank filter finally arrived, quite a few days late i might add. but the thermometer is no where in sight which is a problem because how do i tell if the heater is working? its been plugged in for about 3 hours and i haven't seen it kick on once but it is kinda hot in my room right now. i thought i followed the directions exactly... i turned the blue thing to 77 or 78 and then plugged it in. i know the outlet works because i was just using it earlier. also i bought it online on amazon and it didn't come with a receipt or any proof of purchase, if it is broken will i be able to return it? and it specifically says in the instructions that it has to be placed in the tank vertically, despite being a "fully submersible" heater. i have it in vertically but its very long so i would prefer it to be in the tank slightly sideways or even horizontally on the bottom, is that possible?
the whisper in tank filter is extremely strong, i tried the baffle where you cut up the water bottle but that seemed to actually make it even stronger o.O so i was forced to make up my own. i took craft mesh and made a box, without the lid. then i put a pair of pantyhose inside the box and took another pair and put the legs inside the box and then took the waist and folded it over the sides and tied a string around the bottom to hold the pany hose in place, it isn't pretty but it works amazingly well. i then put strings on the side and tied it into where a have my filter hanging from. i have a couple pictures that might explain it better.
