How much brightwell phosphat e should I dose ?

[Hallowhead]

Howdy !

My tank is overrun with GHA. I've been doing weekly water changes for a month now trying to get it to go away. My phosphates are undetectable, nitrates roughly 10/20. I've been dosing bacter7 and nopox daily.

I have 3 urchins that are doing good work in between my water changes however I know my rocks are absorbed to the brim with phosphate.

What should I dose ?

How old is the tank?

 

[Hallowhead]

Roughly 3 years

I would start at half the recommended dose and increase by 10 to 20 percent weekly until you see good results.

Are your coral holding up well or are they turning pale.

 

[WhatCouldGoWrong71]

Half as much as anyone tells you, wait, test, calculate, dose again.

 

[Hallowhead]

But what am I testing for if it's reading 0 already ?

I'm definitely gonna start supper small, but just not sure what.

My corals just are not growing. Torches were suffocated by the GHA

I wouldn’t dose Phosphate E until you can actually detect phosphate in the water. First place to start with GHA outbreaks manual removal. Do that every few days or at minimum once a week and rely on your CUC to keep new growth under control. You may need to do this for a1-2 months. The key thing is to stay consistent and slowly make progress.

0 is dangerous. You want something. Also, if you are using a Hanna, just realize that they are +\- .05 on PO4. So, my floor when testing with a Hanna is .08, below that, I start adding reefroids and more nori.

I'm using salifert, it's not zero. The GHA is just swallowing it all up.

Whats the tank size? Its super powerful stuff, I would start with a couple of drops and test and dial in from there.

It's reefer 425 XL so roughly 90 gallons display and maybe 15 sump ?

My advice - whatever you do, take it VERY slow and methodical. DO NOT start dosing products you need to ask about on a forum. Do some research as to WHY you are having the problem in the first place and then make a plan.

The very last thing you should do is start dosing something you have 0 idea what you are getting into. Same thing with something like cyano removal products. It's a NUKE to the microfauna in the tank because it's a catch all antibiotic. The rebound is 10x worse than the remedy.

Have you tried Reef Flux?

 

[Randy Holmes-Farley]

I would not try to beat algae by lowering already low phosphate. That risks starving organisms you want., I’d get a bigger clean up crew.

Yes, no luck. Honestly probably made it worse, this was some time ago and 20 or so water changes later now.

I agree, which is why I asked here first, just wish I didn't buy it already. Very pricey lol. I guess good to have in emergency situations.

What else should I add ? The sea hare is a machine and added yesterday so I think I'll continue as is for a bit. Randy would you suggest stopping nopox?

Reef Cleaners sells great clean up crew packages of snails and such.

I would not dose organics to my tank unless nitrate is over 50 ppm.

Never have luck with reef cleaners surviving. I'm in NJ it's either too cold or too hot. But I'm slowly added to my CUC but I'm having unusual snail die off.

Oddly enough, I find that ReefRoids will do a decent job of boosting phosphate, if needed. As many have said, go low & slow. The most I'll add is 1/2 teaspoon to a 90g + sump system. Then wait a couple days and test. I use the Hanna Phosphate tester, couldn't reliably tell the difference between shades of grey with Salifert...

This is what I use

Easy to dose and truly helps a lot
