well i want add som sps but i know they will be gone in matter of days, already have HOB skimmer for 100 gallon max. Talking about my phos are in the right number 8.0 i dont think that phos can b an issue ?

[Cal_stir]

your phos should be 0.3 to 0.8. your ph should be about 8.0 or alkalinity not your phosphate (po4)

Ok my bad i will check my phos

100% water change... Done, zero nitrates.

But it will not crush all my live stock (fish,corals,crabs) i dont really mind i can do 100 water change but do u really think that will finish with my battle?

[pegrochilakila]

It means that i have to cycle my tank once again ? Wait for ammo and nitrite go to zero?
Is kinda risky ?

You can safely do a 100% WC

All the denitrifying bacteria is on rocks and sand. You won't get any where doing small wc as the dilution rate is small

Start feeding less add some mechanical filtration to sump. Ie filter floss or sock. Look into carbon dosing of some sort. Vsv,prodibio etc
