My 200 watt glass heater just exploded in my tank. Does it release anything into the water that I need to be concerned about. Please help if you know.

dont know for sure but heres what wiki said
Most commonly, aquarium heaters are immersion style heaters, these heaters consist of a glass tube containing a heating element wound about a ceramic or glass insert. Some glass immersion heaters also contain sand, and most, but not all, are fully submersible.[1] The glass tube also contains an adjustable thermostat which turns the heating element on to maintain the required temperature.[1] This thermostat is often a bimetallic strip; because the strip contains two metals, the metals will expand at different rates when the temperature rises, causing the strip to bend. This strip carries the current, but breaks the current at the correct temperature. The setting of this bimetallic strip can be adjusted.[4][5] More advanced thermostats may use microchip technology.[4] A small light in the heater is often included to indicate operation.[5]

In a small aquarium, one heater can be used; however, in a larger aquarium, two or more may be used. This has the added advantage of one heater being able to compensate in the event of one heater malfunctioning.

i would be more worried about the glass shards, be careful and unplug it first

It was in my sump so I definitely got all of the glass and pieces out. Thanks for the info so far. It does not say anything about chenicals so I hope that all is well.

Glass heaters break sooner or or later. I've had them break in tanks and trip the system.

I won't ever use a glass heater again.

Anyone know if there are chemicals to worry about?

I have been using the stealth heaters for several years with no problems.

I have not heard of these heaters before. Have any more details?

Nevermind. I looked it up and I've seen them before, just not heard the name.

Yeah I remember for a while those strip steal heaters were selling everywhere and they are supposed to be very safe. Here in Mexico I only use heater for like 3 months only because the tank is outside, I wouldn´t need it if it were inside. So I guess I´m in less risk.

I've had one break before in a FOWLR system Unplug and remove the heater. Then add a filter bag of carbon and place that in the sump. If anything was released, the carbon will probably remove it from your water. If you want to go a step further you could do 10 - 20 percent water change.

Everything seems okay so far. I did a 15% water change right after and I will add the carbon just in case.
