Green water getting greener

[jumpoverit]

Hello
My reefer 350 is now 8 months old. My water is green beyond recognition. I cant even see my fish no more.
Here's what led to it:
* Nitrate was too high (i bought a biopellet)
* water was not clear like at the fish storw ( i bought Carbon)
* phodphate became too high at 0.9 ( i bought a GFO reactor)
Everything worked really well. Now this.... green water......
Im doing a 50% water change but i doubt it will help...
I've read that i now have to buy a UVclarifier....
Here are my parameters
Temp 77 degrees
Salinity 1.027
Alkalinity 11 dkh
Calcium 420 ppm
Phosphate 0.09 ppm
Nitrate 0.76 ppm

All my hammers are dead. Funny but my 2 torches seem to hang on.
Any idea ?

IMO best way to deal with green water is water changes and a UV sterilizer. The green killing machine did wonders on my tank

I was going to make some stupid comment about how yellow and blue make green...but I cannot deny your logic. +1

UV +2 ...
How big is a reefer 350 in gallons? Just be sure to get one that is appropriate wattage for your size...

Water change
filter socks
Carbon
Reduce white light intensity
UV strilizer as indicated

Are you using tap water from the faucet ?
What is your current phosphate levels and what test kits are you using ?
** Is your tank at or near a window??

75 gallons . What size would be recommended?

Most UV will tell you on the box, just make sure to not go under the said recommendation, my guess would be 15 watt ones seem to do up to 100 gallon or so

I go with 13 watts on my 90 gallon, and run the lamp 12 hours a day on a timer. At start I would run yours 24 hrs till water clears. I think you could go as high as 24 watts safely on that size?

I bought a cheaper one as I couldn’t cough up the extra couple hundred for a nicer one

Had that same one on my 90 for 10 years. Well made and well priced imo.

Also replacement lamps are not too bad price wise and easy to find inexpensive online.

Awesome to hear, as I literally just got it a few days ago.

Ya they are an awesome little unit for price. Only reason mine died is I messed up after lamp replacement and forgot the O ring when back in tank doh!!! I would have bought another but wanted to switch to fully submerged unit, so did that last year.

Dang yea. I noticed the little O ring when I unscrewed it, I’ll make a mental note to always make sure that is in place for sure now lol. When you say fully submersible are you referring to the Hang on the back kind ?

 

[jumpoverit]

Would you guys continue to run the carbon. The GFO and the biopettets?

Mine is now in the tank the entire unit, behind the rockwork. I just wanted less hoses or chance of leakage outside tank. Only problem with the new one is the lamp is proprietary and costs around 80 bucks.... sigh.... those Turbo Twist 9w were like 25 bucks for 2 on Amazon lol.

I don't run any of that, rarely Carbon and only if I think there is possibility of contamination.... Carbon will help with yellow colour of water but not sure on the green issue. @vetteguy53081 can advise better that way.

That’s sounds nice, I didn’t know they made them to put in the tank like.

For my 75 gallons I got the Aqua UV adavantage 2000+ from Reef solutions (in Laval, not far from you).

You can get HOB (easier if you can) or barb x barb.

You can buy 5 micron sox, which might filter some of the algae out.
