Corals Not looking hot

Yeah I hear you. How much would you use? Total water volume is 75 gallons was doing 1/2 teaspoon at a time
My general recommendation is to double up every 2-3 days until you can detect phos.

For example:
Day 1: 1/2 tsp (test following day)

Day 3: 1tsp (test following day)

Day 5: 2tsp (test following day)

Etc. until you can consistently read and keep phosphate at a desired level

Keep in mind a phosphate deprived system will consume any and all phos introduced almost immediately during the initial introduction of Reef Roids, it will take a bit to build up but will eventually read steady once established.

Thanks. Will try this. I’ll post another picture once I get home with more white lighting
 
Update for everyone wondering.

FYI, I have a 90 gallon total water volume system...if I dose 1 tsp of reef roids, my phosphates consistently raise by 0.05 to 0.06 when measuring 4 hours later...looks like you got your dosing figured out, but thought I'd share....oh and if I am not careful, in 3-4 days it will bottom out again...so I typically dose 1 tsp twice a week to keep things close to .1 (this is on top of fish feeding, etc)...every system is different, but thought I'd share in case it is helpful.

Thanks for your experience. I have phosphates stable around 0.05 unfortunately corals still look like crap but I’ll keep an eye on everything
