Algae issue...

[L98-Z]

Here's the issue.

I was preparing to cycle my 180 gallon tank with a 40 gallon sump.
I have three 300 watt heaters, 4 Hydor Koralia 4 powerheads, and a rather large return pump.

I placed my sand into the tank, followed by base rock from Bulk Reef Supply. Approximately 100lbs of dry rock. I filled the entire tank up with RO/DI water, which took approximately 2 days.

About twos ago I put salt in it, the next day I noticed it was a little green. I thought nothing of it, in fact, I assumed maybe poor lighting was the cause. I currently have not placed my canopy on top, so no lights are on it. Anxious to get the cycle going, I threw a couple of cocktail shrimp in there.

Today it's pretty green, and smells terrible. I'll drain it if I have to, but I hate losing 40+ dollars in salt. What went wrong and is it too late to fix it?

Did you put any cured live rock in to start the process, or only base rock? If not, I would highly recommend buying as much live rock as you can afford. You currently have no bacteria to start your cycle. HTH

The tank water is green, or the rocks? If it's the water, you may consider adding a UV filter on there. Do you have a skimmer on the tank? That may help as well. And if it stinks, carbon may be a good idea, too. So there's a lot of options, I don't think drain and fill is necessarily going to solve anything. Did you take the shrimp out yet? Usually they only need to be in there for a few hours.

No, no live rock. I was under the assumption the shrimp caused the nitrogen cycle to begin.

I do have a skimmer, I'll give that a try. No, I had not taken the shrimp out, I'll do that as well.

Oops, it's the water that's green. No change in the rocks.

The skimmer appears to be helping. It's now a lighter green, and some of the smell appears to be leaving as well. Hopefully this is making progress towards solving this.

how long where the shrimp in the tank? that could account for the smell. Also, have you seeded the tank with anything like a bit of live rock or live sand? If you just used dry sand and base rock, you'll need to get a source of bacteria from somewhere (just a pound or two of liverock would work).

Gotcha, will do. Shrimp were in over night.
