Just wondering if the intake hole looks acceptable.

I'm 8 weeks into my tank. It was a pre-existing FOWLR that was obviously neglected by the previous owner. Tank was covered in Cyano when I picked it up. I replaced the sandbed when setting it back up. I've been through the diatom phase, which cleared up quickly and cyano showed up next...

Who has corals in a tank where the phosphate isn't exactly 0? Mine is somewhere between 0 and .5. If i add a softie, is it a goner? I'm running a skimmer, use premixed RO/DI water, bag of carbon and phosguard, and I rinse the frozen mysis shrimp in RO water and drain before adding it to the...

I returned home from work to find some brown algae type stuff had developed on my live rock and sand bed. This is a 55 gallon FOWLR system that I bought and recently transferred to my house. I replaced the existing sand with new aragonite sand and put a small layer of existing sand over it...

My tank is a 55 gallon FOWLR setup. It came with 2 x Coralife 65 watt Power Compact 50/50 bulbs. I looked up what 50/50 means and it's 50% daylight spectrum and 50% actinic. When I searched online the combo 50/50 units have 1 white bulb and 1 blue bulb. My lights are both white though. Is...

When you use a HOB skimmer, is it so tall that it stick up above your tank for the world to see?

I've seen suggestions to put Plexiglas on your drywall behind your SW tank. Does anyone really do that? I can see it being more of a problem with an open tank, but mine will have a canopy and an HOB filter so it will be away from the wall a few inches.

I am picking up the FOWLR 55 gallon fully established system tomorrow. I'm looking for any advice for a moving a tank that I have not already thought of. Once the system is broken down, it'll be about 1 hour of drive time back to my house. I have a cooler to transport the fish in. It will...

Hello All, The 55 gallon tank I purchased includes a Mandarin Goby. I am planning on using about half of the sand that is in the tank already and mixing it with new aragonite sand. I am also getting several pounds of live rock. Do you think there will be enough life in the remaining live...

I'm shooting to get a 3" sand bed in the 55 gallon tank I've purchased. I have enough aragonite to get a 2" bed currently. If I throw an inch of already live sand from an existing tank will that be overkill? Do I need to mix the aragonite and live sand together? Thanks!

I'll be picking up the system I bought next weekend and I will be setting it up on a hardword floor. Does anyone use a stress / fatigue mat to setup the cabinet on to protect the floor? I was thinking of maybe getting a rubber mat to put down. Is that overkill?

Hello, I've purchased an existing FOWLR system. I'm curious as to what I should do about keeping the sand. I've seen articles on line that are for keeping to other that suggest only keeping some. I thought I'd poll the community here to get your thoughts. My main concern with keeping the...

I'd like to get some thoughts on in-sump heaters. From articles I've read this sounds to be a newer tech for heating your tank. Does it work as advertised? Meaning does it really heat your water consistently throughout your tank? Thanks!
