I’m in process of setting up new tank. Live sand, dry rock, dr tims and microbacter 7. Next week will be 2 month mark, about a week or week and a half ago I reached 0 ammonia and waited for nitrites to go to 0 which was 2 days ago. Nitrates were present, I did about 40% water change, then I...

Hey y’all so I have a BioCube 16 (as you can see by the title lol) and I guess it was used but I didn’t know this until I went to start cycling, so I ran a water/vinegar solution for about a week. Now I’m at the point where I’m trying to get it ready for the cycle and I noticed the light has...

**Admin/Mods** I accidentally posted this in the soft coral forum, can you please delete from there?** a few weeks back I posted about this same trachy, whether to reposition him or not - ultimately I left him alone based on the advice I received. At that time he was doing well, magnificent...

a few weeks back I posted about this same trachy, whether to reposition him or not - ultimately I left him alone based on the advice I received. At that time he was doing well, magnificent really. He’s been in the tank a couple months and has always been in top form. About 10 days ago I...

Can anyone point me to where I can purchase the o-rings needed for the unions on a Geo 612 calcium reactor????? I would even get the union just to pull the o-ring out of it. Getting them from the orig manufacturer seems to take too long.

Hello once again everyone, I was recently looking at some pictures of others tanks and have seen that some have crazy polyp extension with their LPS, the feeding tentacles, and then others have little to none at all during the day. I am one of the latter, during the day there is very little to...

Please help me , I’m trying to determine if these are percula or ocelaris I was told they are both percula but am not sure

Hey reefers I have a question. I manually dose my 55 gallon tank every day/ every other day depending on consumption of alk/calcium, but would much rather get a dose and have it dose daily throughout the day for increased stability. HOWEVER, I'm extremely curious, how often have dosing pumps...

*For starters i would like to say that there is no fighting in my tank, they all actually have a good amount of space im more concerned about the bioload in the 20 gallon, so give me tips, please. So, Basically to put it simply i fear that i have over populated my 20 gallon long tank. These are...

My tank cycled up fairly quickly with respect to ammonia management - about 2 weeks. I cycled with established LR that I got from a fellow hobbyist -- that LR was also established with some Green and Brown HA. (40b with 20L sump; no fish, CuC only, set-up in Mid Sept 2017) My nitrates climbed...

My zoas went thru a fungal infection a few months ago and now they look like this after furan 2 dips and iodine dips and lots of patients how do I get them back to normal after: before: .

Just found this guy on the outside of my skimmer. He's from TBS Live Rock, so Gulf of Mexico. About 1cm, translucent-ish, pale cream/tan with crazy spikes & antenna. WHAT IS THIS?!?

I recently purchased a 100gal established tank with a 30-40gal sump. The guy I bought it from stated it has been up and running for roughly 7 years. There is very little crushed coral and roughly 125lbs of live rock. the rock is covered in nothing but mushrooms tho. Not that I mind the mushrooms...

I just started a brand new tank (Red Sea Reefer 250). I originally was going to use all Marco Rocks & started using the Red Sea Reef Mature Kit (nitrifying/denitrifying bacteria, No3-PO4-X & KH-Coralline Gro) to help start the tank. I'm now on day 8 out of 21. Plans changed slightly & I ordered...

I got a chloroquine phosphate script filled at a regular pharmacy, not a vet pharmacy, so was dispensed CP pills, not powder. It didn't even occur to me until I got home to question whether or not the fillers added to make pills stick together are inert for reef fish & are safe to use? I need...
