    I've had a 200W model for several years and it's my favorite heater. I did have to remove the plastic grill though.

    Is the grid the problem that's causing the LF to go off?. I have two canister filters what's the best spots to put these heaters? For that matter whats the best spots for the canister hoses for flow? Sorry 2 part of topic question?

    Yeah, it wasn't heating very well. Once I removed the grid it worked like a normal heater just with a more reliable thermostat.

    I always put canister intakes and returns as far apart as possible and heaters as low as possible.

    These heaters are can completely submerge?

    I own 12 300 watt E series, they're a great heater. The low flow is a problem that most heaters have, the only difference is the Fluval tells you about it! Always make sure you have a lot of flow near the heater, so you don't have just one warm area in your tank. Also leave the guard on to protect your fish and the heater.

    so where do you guys have your heaters located?

    Mine are vertical in a chamber in the sump but completely submerged.

    Ok so i hooked up both fluval 300watt heaters on opposite sides of the tank. Both in front of the outlet hoses. For a bout 40mins. One heater reads 75.5 but the other one is still at 70 has not changed at all since i plugged it in. Should i be worried?

    What color is the read out on the one that is at 70?

    Good to know, I have one and dont like it that much because it was pretty inaccurate. I will try removing the plastic :)

    I did get a low flow warning when I had it in certain places as well (again with the mesh on)
  14. Dantheman62445Valued MemberMember

    So aggravating. Had these half the day :(. I will wait til morning.....

    Its a good thing at least that the one reading low is blue, that means it is (or should be at least) heating.
  16. Dantheman62445Valued MemberMember

    How long you think it would take 2 300 watt heaters to heat 75 gallon tank.

    Push the adjustment lever to the right to see what it's set at. If it's where you want it try unplugging it for 1 min so it can reboot.
