Ok thankyou. There is some algae but in all the times I’ve tested nitrate it hasn’t fluctuated from a clear 0. I did a water change to help clean the water for the clownfish today. I think I will order a RedSea test kit.I'm pretty sure your tanks been up long enough to process ammonia. Do you have an algea or cyanobacteria outbreak? That could be using your nitrates up. Other thing could be ich or flukes.
I'm not sure if whats in the gravel is dinos, but if it is, will putting in H202 affect the fish or anemone? I don't want to cause harm to anyone in the tank. Also would it be okay to get a juvenile yellow tang? I want a fish to help with the algae but all of the fish that eat it are very big (tangs, rabbitfish, etc.) Would it be okay to try the tang for a few weeks and return it if it looks stressed?I don't think people will agree with the yellow tang idea. I don't want to admit but I did try a Acanthurus blue tang, (a few year ago) it was very small. Seems like it ate fine, and if I remember correct you need to feed tang's the seaweed which I did. IMO it got stressed because my tank not wide enough and died, was only 55 gallon, he swim all the time mostly in a circle and was semi-aggressive. I won't try again; unrelated butterflyfish also went bad for me.
Using snails or anything to control algae or dinos, diatoms, never worked out for me. Note dinos will be brown and may produce small bubbles, this can be caused by over using carbon, or over doing WC where nitrate and/or po4 are basically zero. Either case causes bacterial imbalance, if you have good bio-load and proper nitrate po4, then algae/dinos can't live b\c bioload is using those nutrients.
To help remove dinos and algae you could dose H202 (hydrogen peroxide). Turn off the water flow, using syringe place h202 directly on affected area. Rule of thumb i hear is 1ml per 10 gallons, but for my tank seems is impossible to add too much, nonetheless start small be careful. This is short term solution if bacterial imbalance remains, adding MicroBacter7 could help. Double check nitrate and po4 balance, and ensure is not too high or low.
Don't take my word alone for it, you can google for example "hydrogen peroxide reef tank". I tell you I've done it with success and without issue. I don't recommend tang because using snails or fish to control something never worked out for me. Removing a fish is a hassle and I've never tried returning one. I don't see corals on the rock you could just remove it from the tank and then put h202 if want to be safe, note h202 turns back into water when exposed to light. If adding directly into tank as I said "Rule of thumb I hear is 1ml per 10 gallons ", and try google :- ] good luckI'm not sure if whats in the gravel is dinos, but if it is, will putting in H202 affect the fish or anemone?

He's seemed fine so far and the people at the store recommended it. I will always view returning it as an option but so far he seems happy and healthy.Ah yes a tang in a 40. I trust you are returning it in a few weeks? Have fun catching it.
