Sump

[jaBX1]

I made a sump a couple months ago. i made sure to get silicone that had no anti-fungal stuff or anything thanks to advice i got from mr.

forget the brand but they had Silicone I or II. Sil I was the one i got.
i beleive II had anti-fungal additives which would leach into an aquarium.

the seals are fine and my tank has been cycling for close to a month now.
i finally got a light for the cabinet and noticed the silicone has discolored to a brown/orange color. Im not sure what it is.

Please help:happysad:

anyone? could this just be a reaction that happend and its over or are there chemicals being leeched into my tank?

the cycle is about done so it hasnt hindered the cycle process.
this is just a temporary sump but i am still concerned

I could be wring but I believe that is a type of algae which normally appears towards the end of a cycle which feasts on silicates, so being on the silicon makes a lot of sense. Look up diatoms I think. Gl

+1 on diatoms. They are normal and should go away with water changes
