Brown slim in my fresh water tub ATO

[Ginu]

Red brown algae in ato container is really really weird... I'm not familiar with sump pumps from Canadian Tire but I think it's safe to assume they must use some type of Vaseline and that could possibly create the brown algae in the ato container. I personally would spend a little more and use equipment which is meant for fishtanks when it comes to stuff which is submersible, or do lots and lots of research before pulling the trigger.


Reason why I ask what kind of rock you were using is because if you started the tank with dry dock, you will get weird brown algae as time goes on and it will take a fairly long time for this rock to become live. I believe the silicates from the dry dock b cause this.

i think your right, i will take back the pump and get one that is aquarium safe and see what happens, i thought it was strange also
the rock i got was from an established tank running for years

The red algae in your tank sounds like cyano. Tanks of all stripes get cyano outbreaks all the time, and the reasons for it are very rarely single issue or can be traced to one causative source. Cyano is a bacteria, and is the most successful group of organsims on the planet, so there's more going on with it than your garden variety algae.

However, the brown slime in your water container is still a problem, and the recommendation for an aquarium safe pump is a good one.
