filtration advice

Hi all, Brand new user here, and praying this gets some traction. I'm embarking on a sort of ridiculous project that it seems like this forum is uniquely poised to help with. I am a PhD student at Duke University studying the functional genomics of how calcifying marine invertebrates (think...

I am currently planning out a 20g long lps reef tank to replace my 10g. I want to take it a step up and get better equipment. First off, I don't know whether a pair of Kessil a80's or an AI prime hd would be a better fit. I haven't been able to find any other lights in that price range that...

Hey all, I have been struggling with nutrient export as of late (along with an outbreak of GHA) and have been working to reduce nitrates and phosphate through all of the traditional routes (water changes, reduction of feeding amount/time, consistent cleaning of filter and protein skimmer, etc.)...

I’ve already got a build thread on here but I’m making a new one since this is a new tank! It’s a BioCube 16 LED and I got it completely dry, with nothing but the tank, pump, and a couple unopened filter cartridges. I did not know it was a used tank, but it is, and I found out after the fact -...

Hey! I finally am on my way to setting up a NEW TANK!! i have a 16g BioCube LED, which I thought was brand new, but now I’m seeing it’s been used. It’s been drained, vacuumed and wiped out but I’m currently running it full with no heater, no filtration in it, just the pump with water and some...

So some background: I inherited this 50 (I am told) gallon Plexiglass tank. It came pre-established (don't know how long, but at least a year). It is a wedge design, with an overflow filter in the back. I have had the water quality tested several times...it is near perfect. I have it tested at...

Hi Everyone. Getting back in after a 15+ year hiatus. Bought a 225gal (72"x24"x30") reef ready tank. 2 corner overflows. Since the technology has changed so much, I'm overwhelmed about what all I need (or want) in my sump below the display tank. Any and all feedback is both welcomed and...

can i use lava rock as part of my filtration?

Hi, I've been thinking about setting up a saltwater tank and setting it up without a sump, or protein skimmer (natural filtration). The tank in question will be a shallow tank, 45-60g with only wavemakers, heaters, rocks, and sand. I'm not sure what else I would need, which is why I'm here. Is...

Hello all, I hardly ever post here and I’m gonna tell a little about my situation first: TLDR at bottom I’ve had a Biocube 32 for 6 years, it still runs okay and my clownfish and clowngoby have been completely healthy, but the corals have all died off except some soft cabbage and I can’t seem...

Hi Guys I am setting up a new tank (first in a good few years - 135g dt, 40g sump) and would like to know your thoughts on weirs. So the tank I have now is a Herbie style with a lower standpipe as the main drain (raised to about about 10 inches above the bottom of the tank) and a durso style as...

Hey guys! I’m going to try to make this as short as possible. I just recently purchased my first house and I’m in the process of moving my reef tank here. I’m currently using a 40 gallon breeder with a Fiji cube aio internal sump (similar to the Fluval evo). My neighbor gave me his old 75...

I will be setting up a new 300L tank soon but I don’t have a sump with it, what good options do I have for filtration preferably that wont crowd the tank with equipment?

Hey Reefers, I have had my tank set up for a few months and I have had some great success and some epic loses. I am trying to set my filtration set up and I have order a ton of stuff but not sure if I need everything. My goal is to have crystal clear water that is beneficial to all the...

Hey guys, I am new to the saltwater world. I currently have 2 freshwater tanks and want to build a beautiful reef tank out of a 40 gallon breeder. I am building this tank on a budget and do not want to break the bank. I am currently interested in the Fiji cube 40 gallon insert but they are sold...

Hi all, looking for recommendations on what other media to put in my AIO back filter chamber(s). Right now its just filter floss in chamber one, and seachem matrix in chamber 2. I have extra amounts of matrix (bio media) to compensate the “small” amount of rock i have in display. i have lots of...

I just ordered the inTank ch1 filter media box because the stock filter is going to become a nitrate heaven. I was wondering on what kind of media I should put in it? I did order filter floss to place at the top of the media basket as well as Marine Pure Gems

What would I have to change to use a sump instead of a Fluval fx6 and Fluval 407? Display tank is 125 gallons, I want the sump tank to be 55 gallons. Any advice on setting up a divider/baffle free sump tank? Can I successfully set up a sump for less than what a Fluval fx6 costs if I already have...
