    Recently got rid of my magnificent fox face for nibbling my zoas. At first I thought he was just cleaning off the rock, then he went right at the center of two polyps. BANISHED!

    Interesting. Could be the culprit.

    Although if I have to choose, I am keeping the fish and just going with different corals.

    Had the fox face for a little over a year without issue then zoas started disappearing.

    Did some spring cleaning.
    Shocking amount of calcium deposits in my heaters.
    I think I will leave the plastic protectors off from now on.

    Wow! I have the same or very similar heaters and don’t have that issue at all. I wonder what the difference is?

    Did you have the plastic on too?

    Yes, I leave it on. It’s kind of hard to remove when I need to for periodic cleaning. I’m worried that the hot titanium will melt something in the sump or hurt my banished cowrie.

    Wow. Haven’t seen that before, is it bad to happen?

    You could leave the calcified stuff on, I mean it'll help protect the heater, it'll warm the water just as much, the only thing I'd worry about is if the boundary layer between the crud and the water is more likely to precipitate your precious calcium and alkalinity into the water...

    or just dunk it all in muriatic acid for a fun fizzy show :D

    I wouldn’t leave it on. It will do 3 undesirable things:

    1. Slow the transfer of heat from the heater to the water, probably without noticeable effect but at least theoretically could lead to wider swings of temp than desired. Not that any heat will be lost, just won’t be as responsive.

    2. Act as a nidus for more rapid precipitation of the calcium, carbonate, and whatever else that stuff is from the elements in your water, wasting supplements and possibly imbalancing them.

    3. Be ugly.

    1. Possibly, also how fast your tank loses temp to the environment, theoretically you may actually have a more consistent temp as the warm crud helps heat your water, I guess it really depends upon the thermal conductivity of "crud"(tm), glass is hardly a great conductor of heat, so it may not be as bad as you might think.

    2. Yeah I figured this would be the biggest issue.

    3. It's in a sump, stuff is supposed to be ugly there. Yeah I know, some people have sumps that are prettier than the display tanks but still, we put heaters there for a reason

    4. It's morning, the caffeine hasn't quite kicked in yet, but I can see some satisifaction of removing it, kind of like picking a scab off when you were a kid.. but again caffeine hasn't kicked in, and I'm patiently waiting for pvc cement to cure. from last night.

    It came off easily. It does not stick all that well to titanium.

    Insulating a heating element is not a good thing. It will make the heater itself substantially
    hotter than designed, possibly leading to failure.
    Those are pure heating elements, no electronics inside, so lower risk, but still a concern.

    Yes, a good question.
    And I have not had this problem in the past.
    About the only big difference is adding Kalkwasser to my dosing system.
    All dosing is done in the sump with the heaters, although there is a big powerhead,
    so strong circulation.

    I need to check Magnesium levels also. Been a while.
