My tank is 350 litre and about a year old. I’ve never had problems with phosphates in the past, but as of recently in the last month they just won’t seem to go down. I bought a TDS meter for my RODI and it’s at 0, and even then I switched them all out to be sure. I’m dosing rowa in a reactor and...

Selling my Alkatronic (Updated Version) as I never found the time to utilize it to its potential. I took it out of the box and went through the setup protocols but never ended up using it, so my loss is your gain on this essentially brand-new system. Probe has been out of water so I would...

Hello, I just finished all the plumbing on my new 40 gal reef tank. I wanted to test and make sure there are no leaks and since I'm not ready because I'm still searching for rock, etc.. I wanted to run a test with just water from the hose and then drain it out when done testing. Once all my...

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.

How do you all feel about ICP testing (and now other types of lab aquarium testing, like microbiome testing and tank DNA tests)? While I could see the results as interesting, I don't really see the overall benefit/value in these types of expensive mail-away tests. Ive never bothered with one, I...

I've heard about the problem of Hanna's Magnesium colorimeter reading high and recently learned that you can fill out a form on the Hanna website to get them to send out a new Reagent to correct the issue. But has anyone not had to do this and is getting similar results to other tests they do? I...

I want more than anything to have a Harlequin Shrimp.. BUT I also don't want to feed it chocolate chip starfish every other week, that could get expensive and my partner thinks chocolate chip starfish are cute, so that eliminates that option. I have been looking into other ways to feed the...

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...

If I test my freshwater bucket for PH before adding salt to raise salinity and adjust to a desired PH, then add my salt. Would I be doing the wrong thing? like how much would salinity change my PH?

The Salifert Ammonia Test is really hard to read for me between 0, <0.15, and 0.25. the readings look different in all types of lighting. Near the window it has a brownish hue to it, not deep brown, but you know... In a white lit room it can be white, yellow or brown depending which way I am...
