the water in the tank is green... =(

it's been doing this for months!! I thought I had it cleared up but I was wrong!

asherah

Oh wow...green water eh? My best advice for you would be to find a local (to your area) saltwater club, and get one of the knowledgable members to help you out.

Sorry. I'm confused. I'm not suggesting the LR is useless. To the contrary, I'm suggesting that the LR should be doing more than just nitrification. I must have misinterpreted your other post. I thought you were speaking of all LR as not being expected to convert Nitrates to anything. Didn't realize you were specifically addressing asherah's LR.
This is why I hardly post on here anymore. Always misinterpreting.

Mark, I think I'm confused now. :)

I'm sugesting that any LR will not elliminate 100% of Nirtate do to the fact that anarobic zones in the LR will not be enough to handle most closed systems.
This is why so many other methods are developed to handle excess Nitrates.

Now I should preface myself by saying I'm hypothesizing via what i have read and the what seems to be a common theme, having to rid Nitrates for a tank

Not sure if you were speaking of LR generally or asherah's specifically here. I initially thought generally. My intent was to point out that generally LR is expected to convert Nitrate to anything....namely Nitrogen. The rest of my post was vaguely alluding to the notion that poor circulation and poor surface agitation could result in a build up of nitrogen.

Yes the theory is that with in the LR there will be anaerobic bacteria that converts Nitrate to Nitrogen. This is not always possible, with high bioloads and rock too dense or too porous.
that is why 'we' have added DSB, Refugiums, and Coil denitrators.

Agreed. But again, I'm not suggesting that LR that can't convert Nitrates to Nitrogen is useless, so I'm not sure what that part of your post is in reference to.

Cheers,

I confused a few people, Sorry.

It started with asherah thinking the LR was bad or no longer good and got off on a tangent.

Again Sorry

J

lol

anyway, i'm done another water change and gave about 1/2 or so of the rocks a good scrub in a bucket of salt water i siphoned off...
i also realized.. there is alot of detrius in my tank! yikes..

so at the end of the month i'm going to buy
carbon,
new nitrate/phosphate tests
new bulbs
and possiably even a diatom filter..

i think that adding something with higher flow couldn't hurt either..i think the rocks need more flow.

asherah

more flow is always good... try to cycle the whole tank as many times in a hour as possible... it will help.

I'd really like to chime in to help you, but I haven't been following along (you refer to a thread that you started before this one..?). It would really help if you listed out a complete specs list of your tank for those of us that aren't familiar with your tank.
