Help with untraceable no3 and nearly untraceable po4

[Blake7393]

Hello, I need some advice on how I can raise my no3 using my AI fuge light without disturbing my ph level to much. My fuge light comes on for 10 hrs on 60% through the night while my display light is off.
Any suggestions on reducing my light timings or light brightness??
Cheers Blake

Use reef roids. Raises po4 easily. Nitrates, use NeoNitro from Brightwell.

Yeah I know I can add things to raise them. I remember reading somewhere that you can raise them by reducing light on sump?? I really don’t want to get involved buying and adding more things if this method is possible

Never heard of that one. I guess shortening the photosynthesis in the sump on opposite light time schedule could work.

Think it might have been on BRStv when I heard about it? Remember thinking when they said to reduce sump light to every other night instead of every night what about the ph drop. Just thought someone on here might have had success with the method? If nobody has I’ll have to get the roids and nitro to sort it as you suggested

Certainly you can reduce macroalgae growth and nutrient uptake by reducing the light cycle. Nothing fancy needed. Reduce time or intensity.

My fuge turned into a large algae scrubber. I ended up cleaning it out and working with my skimmer and filter roller to keep my nutrients where i needed them. After battling dinos caused by double zero No3 and Po4

Do you have any suggestions where I should start with this??

So you have ditched your macroalgae grow section of your sump ?

Cut the time in half?

If dinos rear their ugly heads, don’t wait. Take immediate action to boost nutrients fast, maybe dose silicate, etc.

What’s worked for me better than Reef Roids is Oyster Feast. The “recommended” dose will raise my P to right around 0.1ppm. It seems more predictable than Reef Roids in my tank.

no dinos at the moment. Dinos were the reason i bought the AI fuge light for my sump. It’s been so affective I’ve got a problem with not enough, pain in my **** lol

yes

if I had to do it again, I would use a reactor so it can be taken off line at anytime

Taken offline… you are making me think… what about putting another pump in return section of sump and circulate sump and let display run without sump circulation to raise levels?? Basically like disconnecting a reactor. Just a thought, is this idea stupidity?

Either shorten the amount of time the light is on or reduce how much macro algae you have in there and/or both of these

My worry about reducing my light schedule is the effect it will do to my ph stability. The more I think about it. Maybe I should just get the additives. Was hoping someone would read this and tell me about their success with their light schedule/output used on their macro

Feed more? Hasn’t worked for me (7 times a day) either so I’m currently dosing Randy’s ammonia. Only cost a few $ to mix up. I feed refugium tank reef roids every 2-3 days to have PO4 maintain .02 its a struggle. Probably will start dosing Randy’s PO4 soon as well. Macro’s seem to suck it all up! I don’t even have coral yet!

You can dose N and P or feed more. There’s no way to maintain the whole pH effect and reduce nutrient uptake by lighting change. You also cannot gauge from any other tank how much to change lighting to get nutrients to rise by X amount. It is too situation dependent.
