Help! Sponge causes water to turn red..

[Freshman]

Help! my newly bought second hand eheim 2213 sponge causes the water to turn red! (not blood red... just a light diluted red..)

• Will it affect the fish health?
  
• How can I remove the red colour? w/o changing water?

Please advise..

easier to just do a partial water change

[Jungle-mania]

A. remove filter and wash it with hot water.
B. Water change at 50% every alternate day.
C. Cross finger and hope no fish dies on you.
D. Go and complain to the shop you bought and get a replacement or compensation from the distributor.

Second hand? check with the previous owner, he/she should know what is that.

Hang a packet of activated carbon near the filter outlet for a few days. The discoloration should clear up.

In future, it will be advisable to wash the filtration media properly before using. Especially for second hand equipment.

Thanks all for the help!

Done some water change..the colour is getting better..

If you do decide to go ahead to hang the carbon, just make sure you remove it after a week or so.

my suggestion is not to use 2nd filter sponge.
