Algae
 

I seem to have the same problem on my sand bed. This brownish type algae seems to haunt me every time I set up an new saltwater setup. The good news is it goes away in time. My tank has been set up since the end of December but it is still cycling and it will for quite some time, I have read it takes up to a year to be fully cycled. In that time freak algae blooms aren't uncommon.

How are all of your water parameters ?

Hello! Reading this post, it sounds like the issue I'm having with my new aquarium too! I've recently added about 100lbs of (semi cured) live rock to my aquarium and have also started using my 2x250W HQI pendants as well. (Was this a bad combination to do all at once?) I have a 90g + 20g sump with protein skimmer.

Anyway... I'm now getting a fair bit of brownish algae coming up on the glass at an alarming rate. Some of it looks like brown smears whearas some looks like sticky brown snot-like :rolleyes: stuff. Plus there's other stuff that looks like theads. Here are some pictures:

Here you can see all three types on the front glass.

Here's a corner shot showing just the alarming amount of this on the glass.

A zoomed-out view. You can see that the algae seems to be pointing away from the outflow of water coming up from the sump.

I'm not sure if this is standard brown algae, red algae, dynoflagellates, hair algae, cyanobacteria, or something different altogether. Can someone help? What should I do?

All you can do is make sure your water parameters are where they should be. Also try using Ro water for top off and water changes. One last problem could be the amount of time your lights are on . How long do you keep your lights on each day?

Mine are on from 11am until 9pm.

The weirdest part about the whole thing is my corals have never looked better. Granted they still have a long way to go but they've finally started to color up and are looking healthy.
