need advice on pale corals

[Myka]

I do trust the results from those test kits. What do you have for fish? How big is the tank? What are you using for a skimmer?

Yes, please post pictures.

What bulbs are you using and for how many hours a day are they running?

[Amadod2]

For fish: 1-tomato clown, 1-bi color blend, 1- yellow wrasse, 1-poters angel, 1- sandsifting gobi

For bulbs: 4-ati blue + (3 of them just replaced), 1-ati purple plus that's 9months old, 1-ati coral + also 9 months old. Lights are on from 3pm-10pm, with 1hr start up and shut down with just 2 bulbs

For a skimmer I have a swc 180

I will try and get pics later today

Oh and my tank is 75g

Hmm, that's a lot of light over a 75-gallon. Which fixutre are you using? What type of corals are bleaching? Did the bleaching start after you replaced the Blue Plus bulbs?

I'm using a tek t5 fixture, my colors have always been pale. The corals don't look bleached just pale. A few of them are bleached and are recovering

This is typical of a low nutrient tank syndrome, if you add a few more fish and up the feedings there will be more food for the corals, IMO if you have changed the bulbs recently then the par on the new bulbs are too strong, for the time being I would keep up with waterchanges, feed more add more fish and perhaps only run the 2 blue plus and leave the rest off. Running all your lights will bleached the corals and basically nuke the bleached corals further. Do you get any sunlight or daylight in your home? If so that will help abit. Looking forward to some pics to see what state the corals are in.

I bet you need to add nutrients. I use pohls xtra special and zeofood7 for nitrate and phos. I have a very small bioload in my tanks and need to add nutrients for my corals.
