What is everyone’s favorite order of sump components? I know there are different ways of setting things up and I’d like to hear some opinions. 40 gallon planted reef with mangrove island. 40 gallon oblong sump. The sump has a piece of plexiglass down the middle longways and openings at each end...

does anyone know of a filter that is good for taking out fine particles in water? and what filter would be good for a small reactor to keep fine particles like chemi-pure inside the reactor? Please and thank you :)

Hello! I’m very much a newbie, currently gathering all the information I can before I start putting together my tank. I have a few questions about filtration. I’m sure these questions are answered elsewhere on this site but I haven’t found the exact answers I’m looking for. Here goes: I have a...

Hey all I gotta question to run past y’all. So I’m in the process of putting together a shopping list for a tank. I’ve made up my mind on adding a sump (a 10 gallon aquarium). I also want to run a predominately (or completely) biological/refugium filtration setup. However, I now have a decision...

I've been doing some research on using cryptic zones in place of a skimmer and I'm curious how nutrient export actually happens. Obviously, with a skimmer we physically dump the waste down the drain. With a cryptic zone, sponges and other critters eat the dissolved organics, but nothing is...

Hi all, This is my first post here. I searched some of the key words in my question but haven’t found much, and I read mixed reviews on this subject: I’ve had a 5gal pico reef running for about a month now. It has the stock filter in it. There’s also a cherry shrimp in there. Seems happy...

Heya guys! I apologize beforehand for my long post and if it's in the wrong area, this seems right though but there is a lot of information and weird thing that happened. I am somewhat new to the hobby but I have read basically everything you can about everything concerning the care of horseshoe...

Yesterday I saw a post on R2R that started me down a rabbit hole I didn't even know existed. As someone who has always run a "high quality" carbon in their filtration I never thought twice about it. However, it appears there is quite the debate on running a carbon source in an aquarium. After...

HOB or stand alone protein skimmer rated for up tp 65 gallons $75 plus shipping

Hi guys, I have a question to you all, I been in this hobby for few years already, I must say that I enjoyed very much, I have deal with different equipment's and changing slowly into a more sophisticated or updated systems with the goal of keep my reef safe and everything running and working...

I'm about (hopefully) to order a 200g salt tank. I'm still not sure all the differences are on the filter types, single box, double, no box, hang on the back (not my fav). What are the pros/cons besides water noise?

Filter Sock -> Skimmer -> Refugium -> Calcium Reactor -> Heater -> Return Pump

Hello, I was wondering what type of filtration do people use on the 32G biocube. I was hoping to get to know what everyone uses for each back chambers and what products. I would like to upgrade my stuff really soon. If you have a recommendation or pictures of what y'all did please fill free to...

After doing a decent amount of research the past few days, I came to realize that running a new canister filter on my tank has seemingly led to nitrate issues. There are only 2 clowns and 1 small blenny in tank, yet nitrates have been an issue. I was unaware that many people label canisters as...

hey everyone, attached is an image of how the back of my tank looks like (built in sump 30g total) and i was thinking of adding a filter sock/mesh bag of activated carbon on top of the porcelain rings you see there. i was wondering if anyone has had success using a filter sock/mesh bag for your...

so i’m thinking of starting a refugium for my 30 gallon uni tank (built in sump) and i want to make sure my train of thought is making sense so far as i study refugiums. my plan is to use a 5 gallon tank and store it inside the cabinet my tank is on top of since i have no space elsewhere and the...

Tank depth 12” With 30’’ Eight 18’’ No in a rush to set up it up therefore I wouldn’t mine buying good quality system. Any idea what’s best ? Canister ? Sump? Etc... skimmer

Hey guys, so currently I had to go fallow and am treating my fish in a 20 Long and I put my inverts and rock in a 20 High. I was running a 35 gallon rimless cube with a Seachem tidal 55 and a Fluval PS1 skimmer. While I wait I decided I'm going to sell the 35 cube and upgrade... Now I wanted to...

this is a 75 gallon "reef ready tank" (hardly) in the overflow there are 2 holes. 1 for the return that is 3/4 inch and one for the filtration that is 1 inch. Before going further let me say that I wont be drilling this tank. It isn't mine and I don't want to replace it should it break. So...

Any recommendations on a decent HOB Refugium that isn't too big for a 45g tank? I'm new to these, so not sure what all I need other than a grow light and the refugium.

Hey guys so... i've seen some ceramic bio cube thingys on ebay which i'd like to put in the first chamber of my Evo but dont know if they'd be able to leech anything into the water possibly? ill add a link at the bottom if anyone wants to check them out, i think they look okay and i definitely...

Afternoon All, I thought a quick post regarding this product may help people with the same issues I faced. Having moved from a fully planted freshwater setup I was desperate to keep the original tank and stand (Evolution Aqua Aquascaper 900) 1. To save money 2. I like the overall appearance...

Works in perfect condition! Comes from a previous tank build where it skimmed really well and definitely a must buy if you have a decent sized nano tank and looking for an easy way to get a skimmer added on there. Looking to sell for $120 which includes shipping!

I was wondering does anyone know if it is ok to use chemi pure elite and Phosguard in filtration at same time? I didn't know for sure if for some odd reason mixing the two would have any kind of negative affect on my tank which i wouldn't think so saying its removing things out of my tank not...
