Trying to keep no3 and no4 from bottoming out

[Kooma]

I’ve been finding I am having a hard time bringing my nitrate and phos up.

Any suggestions for keeping these from bottoming out with a large coral load? I have a 32 biocube that is mostly SPS and dose AFR daily. Feed a frozen cube daily and two clowns in the tank. Tanks been up for 8 years.

Right now I have undetectable phos and nitrate, not an issue I’ve had with previous tanks and my SPS is showing the stress.

Thanks!

You can add more fish or specifically dose Nitrates/Phosphates. I used Nyos until I added a ton of fish.
If you do water changes double the time in-between them, or toss in more food but you'll have dirtier filters a lot faster.

I haven’t done a water change in 4 months.

32 biocube, not sure how much I can add for fish, clearly more I guess!

I have been heavily feeding, no changes.

I feel your pain, just got a hair algae outbreak and it’s bottoming out my nitrates

:astonished-face: Is your tank super jam packed with corals?

Nothing huge, but there’s 12 or so SPS, half dozen LPs and a starting a zoa garden. Probably 25-30 corals, so kinda haha
