Hello my Aquarium has been running since april 2016

Lately my sand band starting to ger Brown mostly ansæt Also sneaks up on the rocks and corals.

When it started i had stable parameters for a long time
ALK was 8,5
Ca 430
Mg 1320
No3 was 2-3
Po4 was 0.00 or 0.004

I run ca reaktor

Tryed a 5 Day blackout totally darkning the Aquarium.

After i Lost some fish and now alot of corals.

Last weekend i took the decition to drop my Real Reef rock plates and branches and replaced whit all fresh live rock. Since tank was crashing anyway.

Trew aways my Nyos salt ans started Aquaforest probio method.

It still seems that the Brown stuff is comming back but it dosent get boubles

Though at first it was dinos. So threaded whit dinoxal during blackout and skimmed aggressive.

Now today 1 week after the re do its still there my po4 is at

0,15 ppm hanna URL checker
Nitrates 25 ppm.

Ca has raisen to 460
ALK raisen to 10,5
Mg raisen to 1400

Im guessing its becurse of the reaktor dripping same dose and corals are stressed so they dint have same uptake.

Tryed to measure silicates whit salifer it says 0.00

Yet i installed Resin filter on the ro unit.

Running reactor whit Aquaforest zeovit and po4 media and one reactor whit Carbon

Doing bio s and Pro bio f (started Pro bio s today)

Lights are ecotech radion G4 xr30 Pro running corallab AB+ profile 10 hours. Day.

I need some feed back to i Can get this Reef on its right track and save last corals and fish so really hoping for some help here

Also trying to suck it out whit waterchange but it comes back in a few hours.

Algae in the pics are diatomee
Those depends from presence of silicates in your RO water
Those are also comon in young Reef tanks and no need of chemical treatments
If you want to erase simply rum an antisilicate filter post ro water
Filter
