Please help my local Petco solve this problem . . . .

[Pico]

These are pictures from my local Petco that has some saltwater aquariums. The aquarium manager is a very nice guy and would like some help.

I did the testing for him (he only has the off the shelf API stuff)
Nitrate (Nyos) - 5 ppm
Phosphate (Hanna ULM) - 0.90 ppm

I thought he had a low nutrient problem but his phosphates are sky high. Is it because Nitrates are so low, relatively?

My observations: they keep very few fish. It is a low volume store. They only feed once a day. They are using T5s and the worst tanks had 2 bulbs running (tanks with 1 bulb were better or clear). In addition, running mostly white.

Thoughts on what it is and what they should do? Thanks.

Are these individual tanks with HoB filtration or are they all tied in to a larger system/sump?

Possibly cyano?

Looks like cyano to me. When I managed a fish department I would just treat the whole system with chemiclean to take care of it then do a large water change after treatment

+1 on suggesting Chemiclean @Brymac1

Are they using rodi water?

 

[optionrj]

Seems like every Petco is like that. My local one is worse than that!

 

[Pico]

Are they using rodi water?

Great question, I should have asked them this. I would expect they do not.

I don’t think my petco does abs they have tanks full of algae and that’ would be why as well as a reason for the high po4. Cyano grows in low flow if anyone has it you need more flow which I’m sure they do not have power heads and not very much return flow In those tanks if it’s a standard petco commercial marine land rack system

Thanks for your reply. It is a Standard Commercial Marineland Rack System - I had never seen one before
