Hello! I have a 75 gallon tank which has been up for about 2 years now, ~100 pounds of live rock with various corals and fish. I've been fighting hair algae the past few months now and it is driving me bonkers. I recently submitted an ICP test and everything seems great. Had a few minor...

Won this coral by bid just over a year ago. It was listed as ‘yellow eyed favia’. It was like 1 inch in size when i got it. It grows slow but it suddenly will have a growth spurt sometimes. Its now on a 2 inch plate cause it over grew the one it came on. I realised the polyps are getting bigger...

Hey all, I am new to reef tanks and since I live in a compact space for the moment the fluval EVO 13.5 is all I really have room for. I know it is going to be harder to upkeep than a larger tank would be but I have to make do with what I have. I am currently running everything stock. Other...

So after 10 years I finally decided to get an auto doser. Now i was tracking my alk and calcium for 4 days to find out how much to dose daily and i saw a trend where my alk drops 0.3 a day. Calcium is abit weird. Anyway today was the 5th day of testing. First day alk was 8 then 7.7 then 7.3 then...

So right now, my urchin climbed my glass and I'm currently wondering... how. How does he attach himself to the glass? I thought that maybe he has a foot by its mouth but then I saw his mouth faced up to the surface (I was feeding him nori) and realized he's gripping the glass with his side...

Personally, I've been siphoning out around 10 to 15 gallons of my 90 gal tank into buckets, dump them in bathtub, then AC pump it back in to the display. Doing this obviously causes my tank to become cloudy, disrupt my sand bed, and stress my inhabitants. What do you guys do to lessen the...

I purchased 2 strawberry conch. For a week after purchase they were SUPER active and exploratory. One still is 2 weeks later but for the last 3 days the other one hasn't moved. Is it stuck? When you see the picture you'll understand why I'm concerned about it being stuck.

This may be a stupid question but can I cover my tank with a blanket? I have a 90 gallon tank with a sump that has a skimmer. I feel like that may have enough gas exchange but I'm afraid that I may suffocate my fish. It's a light blanket primarily being used to block off light from the tank. The...

I picked up a bit of CUC to clean my tank of diatoms. Do hermits and shrimp eat that? I was told they do but I haven't seen them actually eat any of it. My Mexican grazing snails, conch, and urchin are doing almost all the work. When I feed Flakes I feed just for my fish but when I feed Flakes...

Hello guys, I’ve got a question regarding aquaforest calcium. They say to dissolve in 1L water and dose 100ml per 100L of tank water. Well my tank is 100L and me adding 100ml of water a day to raise the calcium by 18 is gonna make my tank overflow lol. They say you can make it concentrated so...

Is this a good kit to buy? It's 20 gallons, hood, heater, light, and filter. Only thing I "dont" like is the filter. Will it be good enough for just a few weeks worth of quarantine at a time...
