[jimwat]

If you have RO/DI and no fish, do you have any idea where the excess nutrients are comming from?

[der_wille_zur_macht]

What equipment do you have on the tank? Are you feeding the tank at all?

How the heck did you fit 120 lbs of rock in a 29g tank?

[toasty23]

i dont feed, im not sure if i had some die off on the rock i dont think i did. i have about a 30 gal sump full of rock . how do i get rid of phos.

[der_wille_zur_macht]

What equipment do you have on the tank (especially for nutrient export?) Skimmer? Filters? Powerheads? Anything?

What is your water change schedule?

What are your phosphate levels?

[toasty23]

on equip i have 65 coralife skimmer maxi jet . CL with quite one 4000. and a mag 7 return from sump

[jimwat]

Nevermind. I see you are using live rock from from an old tank. My guess is the nutrients are leaching from there.

Water changes. Some type of phosphate removal (phosban, rowa, etc). You might also try some plants (cheato) in your fuge if you haven't already.

[toasty23]

yeah i got cheato . water changes are every 1.5 weeks. and my phos are at ~1.0-1.5. Too high ? i think this is my prob

[jimwat]

There was an interesting thread on keeping your tank dark for a few days every month to help keep down the of algae growth (sorry no linky). I've been thinking about trying this one myself.

[toasty23]

sweet im going to try it because i dont like chems in my tanks never use them > thank you for the help

[ljosh]

You should try a phosban reactor. Change the media weekly until it drops down. It worked for me and I no longer have to use the reactor. Also pick or scrub as much of the algae as you can

[toasty23]

are the reactor pricey?

[jsr]

Drs. Foster/Smith has one on sale for $33.59, without media. The media will cost you about $15 or $20. I use one on my 135G and it does the trick. I also use the PhosGuard media, which is a pellet.

If you have 120lbs of LR in a 29 gal. you can't have more than a quart of water in there!! You could do water changes with a tablespoon. LOL

[toasty23]

i have two tanks a 29gal and a 30gal as a sump. lol with a teaspoon HAHAH i really do like
