Hello everyone! My tank is a 80 gallon with a 13 gallon sump, its been running since March and most things have generally been going good. I started the tank up with a Maxspect R420 putting out about 220 par at the surface. My nutrition values have been pretty stable from the beginning, sitting...

What I thought were Diatoms turned out to be Dinos on most of substrate and tank walls. I bought a microscope to verify. Photos and video are attached. These were my parameters last night Before I dosed Phosphate per some research cause they were bottomed out. Temp 81 Salinity 1.026 Ca 340 KH 8...

Hi all, Does anyone know what it means when the ULR Phosphate checker blinks 0.00? I’ve had a zero reading before, but never blinking.

Ok, so I know this is a highly debated topic, and ultimately most people recommend both ultra low range checkers, but my question is for a newly set up tank where phosphate could easily be above the maximum range of the ultra low range checkers (0.9ppm i believe). Would it be better to get the...

So I’ve been battling hair algae for a while and slowly starting to get it under control. I’ve been tipped off that I’m getting a Hanna ULR phosphate tester for Christmas, so I’ve been using API in the mean time. I have noticed certain part of my tank the algae has cleared up, on the other side...

Hi so I have a pretty new tank, only 5 months old about, and I have two things I am questioning. First, I had somewhat high phosphates in July they were about .48, and my nitrates have never been higher than 6ppm on my Red Sea test kit. But I have a lot of green hair algae, which I thought came...

My phosphate is zero. How much phosphate do you add daily/weekly or monthly? I’m using salifert test kits. I bought Brightwell neophos. I started dosing 7 ml for three days now and it’s still reading zero. 6 months old tank. Thanks in advance!

It's my fault. I switched out my entire sumps bacteria filled substrate and biofilter media and replaced it with calcium reactor media and crushed coral. It's been a month with no problems until the last couple of days. Just tested phosphate (0.06) to decide if I need a large water change to...

Hi, My refugium is doing wanders for nitrate levels, but not much for my phosophates, I'm interested in other peoples experience in this regard. My nitrates started to bottom out, so I dosed potassium nitrate to bring my levels up to 3ppm. My phosophate, sits at 0.15 - 0.2. My nitrate went...

Does anyone have experience with Brightwell aquatics “ExtraxPhos”? Good or bad? I know there are tons of phosphate absorbing media out there but this one was appealing to me because it claims the 600g bag can eliminate up to 30 mg/L from 300gal of water. For less that $15 this sounds very...
