I concur with bruce. The way you are ovwratocking and overfeeding will cause a crash. It will be sudden and fast if you continue like this.
If you attempted to artificially reduce no3 and po4 quick using nopox you will deal with never ending cyano.
Carbon dosing is a bio filtration method is recommended to be used from day one, using it as temp remedies will only bring bad long term issues.
It's always a bad advice to use carbon dosing (nopox,vodka..etc) temporarily or to quickly drop nutrients. Especially when given to a new reefer...It will always be followed by cyano unless done very carefully...
Feed less...fish do not need 4 times a day feeding, especially depending on how much you feed.
Stop adding live stock
Keep up with husbandry, weekly water change and good mechanical filtration
Run activated carbon if you do not already
You can use some gfo to reduce po4 but do it slowly(high no3 and low po4 is common with cyano outbrraks)
Be patient and let your system mature. 2 months is nothing...
Do your research, choose a bio filtration method(carbon dosing,activated carbon and gfo, fug, bacterial additive based..etc) and stick to it and give it time. Usually it's never good idea to mix and match systems.
Example: if you read about the carbon dosing like nopox, usually you will see that you cannot pair it with fug and cheetos cause carbon dosing creat low nutrient environment that cheetos struggle to thrive in.. this is just an example.
Also based on the method you choose the cycle will differ. For natural cycling (Without artificial bacterial additives ) as an example, i would consider tablets 3 months before I add the slightest coral. And at least 6 months before any sps..
While with bacterial additive programs you can shorten this maybe to 2 months....etc.
