so, funny story, or not so funny, just funny to me.

so, i have cycled my tank maybe 3 weeks ago or so (i would have to check my build thread to see when it finished), but at the height of the ammonia at the start, i got it to 2, and waited patiently for ammonia to disappear, which it eventually did about 2 weeks later if i recall right.
the cycle was completed. i confirmed the totals with the LFS, and they saw the same thing, so i got some chromis, and they have been alive and well since. a week or two later, added 2 clownfish, also doing well since then. another week and a half goes, i move my bi color angel from my old tank to this new tank, and since then, which has been about 3 weeks, going well. long story short, all fish are doing great, no issues.
i am however, going through the ugly stage, which is normal of course. i am ultimately wanting to ensure that i dont get any dinos or other algaes that are of the harmful type, so ive been feeding, and overfeeding to try to get phosphates up. ive done the round-about way of testing for dinos and it doesnt seem to be dinos (taking a sample of the algae, and filtering it into a jar), so with that, im not overly concerned with it quite yet, but the wierdest thing is that i cant get my nitrates and phosphates up.

i know that most people will strive for this, but the nitrates and phosphates have never gotten elevated. period. even after the cycle, nitrates were about 5. phosphates 0. to this day, even with overfeeding as much as i can, nitrates and phosphates still where they were before, whcih to me, is odd considering that the cycle process should have elevated the nitrates just in itself. ive tested with 3 different kits including API, red sea, and nyos, as well as the LFS kit.

i dont have any skimming going, or anything that should reduce either parameter. i do have a sump, but only filter socks and pinky filtration. i have been even trying sinking pellets to see if i can get it to leech off anything to raise nitrates/phos. i normally feed thera+ pellets and flake food.

so, i guess my question is, any thoughts on why these two params arent rising, when in theory, they should? most people probably wouldnt complain about these being low, but i think this new tank and low nitrates is affecting zoas, and could create issues with algaes later on.
my only assumption that i can come up with is that the diatoms are keeping them that way, but i dont know personally, if algaes will do that to the point that it is right now. i have been turkey basting and sucking as much off toward the end of the day.

im not too much concerned with how to raise these parameters, because i know i can dose it if i wanted to, unless you have any home remedies, or other suggestions on how much to overfeed. ultimately, i want to make sure dinos or other detrimental algaes, arent an issue (i would rather fight them before they become one). i am trying to patiently wait for a time to move all of my zoas and my hammer coral over, but until i can get through this ugly stage, it is pausing it all. with the lack of nitrates and phosphates, it seems odd since it hasnt raised since the time i did the cycle which is well over a month, almost two.

p.s. its a 65 gal tank
 
a lot of the nitrates and phosphates are probably getting directly bound by the new rock and algae growth (probably diatoms). I wouldnt overfeed anymore and wait out the phase simply blowing off the algae and sucking it up during regular water changes, especially if the inhabitants of the tank are doing well.
Honestly though it is super hard to test phosphate under .04 without a hanna checker phosphorous test. I have tried before with nyos and with salifert and it showed nothing, finally got the hanna and it tested .018.

This ^
will add that when lights come on phosphate gets consumed so check in morning before lights come on might show you some

ya, i get that with the nyos. there is very little color difference between 0 and .07ish. the api kit reads it as .25, which i would is false, seeing as i would trust the nyos to reflect a more accurate number if it were really that high. i would suspect that i have some phosphate, but definately less than .1, which is where i would almost prefer it to be.

my large concern is that the algae will be dangerous. over the course of friday to yesterday evening, the stuff on the bottom had gotten stringy, which generally is a sign of dinos, and dont want to get to a stage like that. the home method test still doesnt indicate dinos, so im not too concerned
 
there are different types of dinos, but post a pic hopefully it is just diatoms. How is the flowrate in the tank right now?
 
good to know. ill check that in the morning
Couple more noodles for thought to get established and out of uglies.
- blow off the rocks with turkey baster once or twice a week. Definitely before water change while debris is still floating around.
- get calcium level right and seed for coraline because where coraline grows other algea will have a harder time

ill get started with the coraline right away. calcium is already where it should be, so i will look into doing that just after the holidays, probably. dont think i can get it local, so i will probably have to order.

flow rate through the tank, minus a small deadspot here or there, i would probably rate as medium flow.

these are the best pics i could come up with. the phone wants to make the pictures bluer than they really are. i just turkey basted these last night, so they arent horrible at the moment

No lfs or local reefer you can buy a rock with coraline from?
Scrape off as much as you can from rock, turn off pumps, sprinkle onto your rockwork

no LFS that sells it. i would have to drive about 40mins to the closest lfs that does. i do have petco, but i dont recall if they sell it.
 
I wouldn't even worry about trying to seed coraline in a new tank. Nothing will happen till maybe 6 months. Best thing you can do is good tank husbandry to work through the ugly stages, weekly water changes. Manual removal, cut lights to 8 hours with no night lights, etc... as you stated there are various ways to bring your nitrates and phosphate up but with diatoms in bloom you don't need to worry about dinos yet. After diatoms will be GHA most likely so get your cleaner crew set and get good Hanna checkers to keep track of your parameters.
