annoyed with sps colors

[deerhunter06]

phos undetectable with Hanna checker nitrates 0

green slimer getting brownish tint why won't it just stay green? it has grown alot, is it not getting enough light?

I have 2 250w MH, a dual t5 and an led strip with like 190 leds.

Your very first sentence answers the whole question

Your trying to get photosynthesis from thin air
Read up on what zooxanthellae needs to survive
Its an algae and with no no3 and po4 it will not happen

Your very first sentence answers the whole question

and that is?

 

[Dan1789]

You need a little phosphate, but try to stay at or under .08

 

[BryanS4]

I hate to ask, but what are your other parameters? I would say it has more than enough light, that's not the problem.

 

[deerhunter06]

I have bubble algae so I'm sure there is SOME phosphates but with the 736 it's undetectable.

 

[twilliard]

Your forgetting about the nitrates

Correct 0 po4 and 0 no3 no good.
That said if your # are that low your coral must bleach and yours is turning brown.
Is might be something else, like a metal of some sort in your water.
It that green Slimmer your only SPS?
How's flow?
How often do you a WC?
What is ALK, CAL, MAG?
Do you dose and if you do How?

Doesn't thriving zooxanthellae make corals turn brown, caused by excessive nutrients ?

 

[twilliard]

But in your case there isn't anything
Bring these levels back to check and you will see them come back
Excess nutrients causes browning lets not get confused what "nutrients" are

Whats your ph
Alk
Cal
Temp swings
Lighting schedule?

 

[Chaz D]

How are the other corals in your tank doing? Is it just this slimer?

No I have a lot of sps, flow is mp40 and gyre 150 both on 100%, WC once a month 30g, alk 8 never changes calc 410 mg 1350, kalk in my ATO, and fauna marin color elements every few days.

Whats your ph
Alk
Cal
Temp swings
Lighting schedule?

I have major ph issues 8.1 during the day 7.6 at night but I have done literally everything to correct it and I cannot. I ran an outside line to my skimmer and for about 2 weeks it was 8.3 during day and 7.8 at night but it slowly went back to 8.1-7.6. my corals still grow well tho. 1 degree temp swing from day to night 82 to 81, other params listed above.

Feed. Feed. Feed. Corals need to eat also.

 

[hybridazn]

Even with dosing kalk your ph drops that much at night? Are you running a fuge light or anything opposite the main tank lights?

What size is your tank?

 

[twilliard]

Feed. Feed. Feed. Corals need to eat also.

Well there is a catch 22 to that.
The more you feed the more nutrients you add and unless you have good export of these nutrients coral can brown out

 

[deerhunter06]

Even with dosing kalk your ph drops that much at night? Are you running a fuge light or anything opposite the main tank lights?

What size is your tank?

yes, I really have tried everything except a CO2 scrubber. my fuge has opposite light cycle as DT. I dose 9tsp of kalk in a 5g of rodi water. 120g tank 30g sump

 

[deerhunter06]

I think my skimmer is underrated for my tank, I bought another one today maybe that'll help. the one I have now is RO 110sss
