Can someone please come help me with my tank

[Stroker347]

I have a 150 gallon reef tank...for over a year and a half all i had for filtration was a 10 gallon tank with some live rocks and a coralife skimmer rated for a 60 gallon tank all corals were thriving and never had a problem...after hearing everyone tell me i was insane for doing so i decided up upgrade to a 50 gallon sump/fuge with an ETSS600 skimmer about a month ago... well i guess in doing so i cause i mini cycle and lost a lot of corals..i did multiple water changes but for some reason my corals are still dying ..all my parameters seem to be in check...but i dunno if i'm missing something
so if someone is not too busy on friday or saturday and has a test kit that can stop by for a couple minutes to see if they can find out whats the problem i would greatly appreciate it.. im located on Ocean and Foster ave in Brooklyn..i have included a before and after shot of my tank..3/4 of my corals have died

 

[Stroker347]

oh yea ...lesson learned...if it aint broke..dont try and fix it

By going to a bigger skimmer you probably are taking all the nutrient from the tank.
Is the skimmer pulling out anything. Did you change your feedind.

 

[Stroker347]

i actually stopped running the skimmer for about the last 2 weeks...my nitrite/nitrate are at 0ppm
ph is at 8.2..ammonia is at 0..i didnt change feeding either..i have 2 clowns, 4 chromis, 1 foxface,1 tang, 1 six line, 1 fire fish

Salinity and Temp?

how are your lights doing? are your bulbs in good shape

 

[Stroker347]

just got new phoenix hexarc blue 14k bulbs 2 months ago..salinity is 1026 temp is always 75 degrees.. the heat from the bulbs has always kept water temp at 75 so i never needed a heater

What about at night?

+1...IMO, you should have a heater, even just as insurance!

 

[Stroker347]

the lowest i have seen the temp drop is 73.7and that was the summer when i had ac on blast..i have good heating in my apt building..and rather than pay for a chiller i just leave air conditioning on pretty much all summer

 

[Stroker347]

i do have a couple heaters laying around i could use as an emergency tho..

I see no coralline algae in there and I'd expect to see it after 1 1/2 years - do you know what your Ca, Alk & Mg levels are in the tank?

Also, what types of food fo you feed?

 

[Stroker347]

yea its been growing very slowly on the glass..i have alot of the green coraline growing in the front of the glass ..i have to scrape it constantly..i have a lot of purple coraline on most of the rocks..and i havent checked the cal/alk level yet

 

[Stroker347]

i have been feeding frozen mysis and ocean nutrition formula two flakes since day 1 and occasionally lettuce for the tang

Without knowing your cal,alk and mag levels I'm going to GUESS that the temperature swings could be causing you to lose corals. 77 down to 73 is a pretty large temp swing.

 

[Stroker347]

my temp is 75 not 77..but im def going to get the cal, alk an mag tested tomorrow

did you buy the sump new or used if its used check for copper leaching. there is no way the problem was by upgrading 40 gallons more. i occasionally add and remove 200 gallons on my system with no effect

 

[Stroker347]

the sump was a 50 gallon tank i always had i used it to cure live rock in ..how can i check for copper leaching????

With a copper test kit.
