Sincere thanks to everyone who pitched in with all the great advice. I really appreciate it.
Running GFO and NoPox have brought down the phosphates to 0.04 on the RedSea test kit and nitrates to 5 to 10ppm on API. I am also running the Nitraguard titanium but too early to see results yet. I dIdnt manage to get the Salifert test kits since didnt see it in stock 2 of my close by LFS. But since API test was showing 80 earlier i am happy!!
On a different note, i switched from Aquaforest salt to Tropic Marin Pro-reef, no real reason other than i just wanted to use their All-for-reef as a simpler dosing manual mechanism with just one measurement than use a doser, and i thought made sense to switch salts as well so the dosing is compatible with the salt.
All-for-reef is Powerful! I think i dosed arround 20 ml (in my 350 ltr tank which is very lightly loaded at the moment : 4 fish 1 big bubble coral and some zoas) and the Mag jumped from 1250 to 1365, calcium from 320 to 380 and alk from 5.8 to 6.8 : yes i have not been keeping my parameters in order but getting to it now after i have the Nitrate and Phosphate under control.
Now i need to tackle my bryopsis problem before i can finally go and add corals. Hair algae is growing all over (not crazy but it is over all the rocks and the back walls). And i saw bubble algae today (the horror the horror :(( )
So now from nitrates battle which i think i am winning, i need to win the algae battle:
I under dosed Vibrant last week to get rid of the hair algae. It did appear to weaken it but then i saw cyano start to appear so i stopped. (i had this previous issue with Vibrant and i think its more to do with my tank rather than the product itself which i am sure is great) So i am going to do it the slow and steady way of blasting my rocks with a turkey baster everyday and scrapping it off the back walls with regular daily NoPox.
I have to admit one more possible problem area : lack of cleanup crew. I didnt really pay much attention to it. I have like 2 turbo snails, 1 stomata snail, a few (maybe 3) nassarius snails and 1 red fire shrimp. A tuxedo urchin passed away due to the nitrate spike earlier. Looking at the wisdom of gurus from youtube, i think i need like 1 cleanup crew per gallon of my tank (ie arround 60 in all!?) Even if i dont get so many i will get i think arround 5 more turbo snails and a tuxedo urchin to help with the algae.
I heard emerald crabs are good as well and eat bubble algae. Any advice of which LFS i can get those? Also any advice on clean up crew stocking for a 350 litre tank would be much appreciated!!
