ok, so I gets nuts here, beleave me, really nuts.

so I both 3 marine land visi-therm heaters, 300W each to heat 100 gallon.

all fine, all 3 put at its max, and conected to my controller, that wil put all one at once at the set point of my controller (79 deg.)

so after 3 weeks running fine, hmm, my tank water is realy cold (74), hmm, how come.

checking the heater's, all fine (at least there LED is on) so you think, all fine, than I thought, lets put the power meter on it (that shows how much wat I use) and bang, only 220 watt for the 3 heaters.


checking the amparage draw on my controller, and bang, only 2.2 amp draw for 900 watt heater.


so I take them out, and 2 are cold, and what I do douse not matter, thy are gust cold.

so quickly to the LFS to pick up A heater, gust to bump things up

thy only had a topfin (douse not matter, as long as I can bring my temp up)

the local reef stoor was closed, so ok the topfin


running it for 4 days, temp all in check, and now, bang, down to 74 again.

checking everything, and beleave it ore not, now the topfin heater gave way.

again the LED working fine, but gust no heat, even if I dile the temp regulator, the LED is going on and off, but no heat.


FFFFF, I gust dont have time tomorrow to get a new heater again.

so the last 2 weeks I went threw 3 heaters, and 2 brands FFFF

the heaters say that thy are fully submerseble, but I wonder if this is right, as in the first 2 that went, I se moisture
