Long story short, I have a 20g long with a Nero 3 and an AI Blade. They’ve both been working well, and I haven’t really had issues with them. My tank has been running for a few years and was doing great until life got busy (kids!). It didn’t get the attention it deserved for a while, and I’ve...

Hey fellow reefers, I have a 20-gallon long tank that’s been running since 2021, and I’ve been having trouble getting any phosphate readings lately. I’ve been tracking my parameters daily for a week now and dosing nitrate, magnesium, and phosphate (all Brightwell Aquatics products). That’s...

Anyone tried this stuff yet? It seems like a newer product, didn't find any reviews. I've had a small amount of Red slime that I can't seem to get rid of. I siphon it away and it comes back in a week or so, thought about trying this stuff. Nitrates 5-7 phosphate .01-.03 (trident NP) It...

Hi folks, Trying to figure out my next course of action. The past 1-2 weeks I've started to see a rapid growth of what appears to be Cyno and a certain type of algae which I'm unable to confirm exactly what kind, still new to all this. I'm currently doing a 72 blackout to see if that helps...

Hello Reefers, I’ve got this red carpet like thing taking over my tanks (see pics). It started off brown so I got a Mexican Turbo Snail which seemed to be doing a good job. Now it’s turned to a red carpet and some parts have really long green grass type things growing. Not sure what it is...

I'm not sure what this algae is, it grows like crazy and very fast. I thought it was cyno so I bought some chemiclean and put that in the water and followed the instructions on the box. it looked great afterwards, nice white sand, but its back but it doesn't look like it used to. it looked...

Help!!!!! So all my livestock has been in this tank for a couple months. I think everything has been in here since March 29th 2021. The 2 Cerith snails I believe i got a little later Maybe early June. So introducing stuff only could have happened awhile which leads me to my first observation. I...

I have attached a picture of this unknown algae or diatom growing on a zoa colony. You can see it directly in the center of the zoas where there is a bare spot. Any help would be appreciated!

Hello all, relatively new to saltwater tanks- I’ve been keeping freshwater for about a year with pretty good success, my first saltwater reef tank is a Coralife Biocube 32 gallon, using the coralife protein skimmer, 265gph pump, and 265 gph powerhead, working on a UV skimmer. Started off with an...
