Test results

[iamahab]

Calcium 498
Alk 176
Mag 1800
Phos. 0.25 ( I’m using phosguard to lower it )
I used Hanna testers. The mag might be off lol. I have a evo 13.5 that’s almost two years old. I do weekly water changes ( 4 gallons) and I’m using a back chamber to grow chaeto. I have a Kessil a80 I run on blue only for 10 to 12 hours a day. I do not dose and rarely use reef foods. Most of my coral are growing but a few pallies and my yellow hammer are shrinking. Id like to get my numbers to a better place but I’m unsure how to go about this, any suggestions are welcome and appreciated.

So, what is your nitrate? Can you share pictures of your tanks. Additional info will help others help you.

 

[iamahab]

Don’t have a pic right now, nitrates are about 5.0 or so

Need both nutrient levels, what’s phosphate level.

He posted phosphate level at 0.25

I think lowing the magnesium may help. 1250-1500

Missed that, those levels except MG, look good.
If your not dosing MG, 1800 seems odd.
If they are stable numbers, Id leave them where they are.
What is your opinion of “better place”.

Water changes weekly at 30% to much IMM. Large water changes lower nutrient levels and can create instability.

A gallon or two would fine.

I used a Hanna mag checker and I’ve read the reagent they first used was unstable, either way I’m guessing it’s not accurate. I was using the Red Sea test kit for magnesium and that was usually around the 1400 mark.

I'd try to slowly drop Phosphates. I'd alternate Phosguard and GFO in a bag, swapping each when exhausted.
That way the Al from Phosguard is removed by the GFO, and the Ba from the GFO is removed by the Phosguard

Most problems with Euphillia are flow related - they're tricky coral
