Well that should bring you guys up to speed

Here is where im at and asking for some HELP/advise

Over the last month after the new addition of the goby and new pump (gyre) and maybe even new bio load I've noticed SPS not happy some colonies STN and losing tissue others less polyp extension and just not looking like the pics from few months ago

After testing retesting and looking back at my log book I narrowed it down to a few things

1) flow got crazy high with the new3 pump I changed from 2 mp10s on wave mode to 2mp10s plus gyre and I changed from a lot of wave flow to direct flow resulting in tissue loss on sps in the direct flow

2) sand goby while nice kicked up insane amount on sand in the first few weeks releasing stuff into my water that's hasn't been stirred in over a year that paired with flow probably made the sand storm sand blast that didn't help with tissue loss
3) tho ive done water changes same 2weeks seems tho im not catching up with p04 anymore and probably not changing my GFO fast enough for the new nutrient released from the sand bed

4) I did a full water test after my 2 week 25G WC yesterday and also I pulled out my old nitrate test that hasn't needed to be used for years and Found the problem

Calc-450
Alk-7.5
Mag-1325
Phos-0.20 Hanna (usually 0.10 after 2 weeks ) so this has been slowly rising last month
Nitrate- 30 !!! omg this has been zero for years I stopped testing it now since add of new fish this is 30 bingo

So .. Aside from anther WC on Thursday whats my plan of attack? I slowed the pumps and my next plan is to start carbon dosing with vodka maybe as my current 2 week wc plus GFo and Carbon isn't cutting it


Your help is needed thanks
