water

Can anyone enlighten me on what this is and/or a cause? First time I’ve ever noticed it. White/greyish film at the water’s surface. If I gently place a paper towel on the surface, it soaks much of it up and I can’t see as much from looking below. In the picture, the white lines circle where the...

As many times I got valuable information from this forum, I want to share my new experiences to pursuit the most crystal and clear water I can. I have three tanks: - one AIO hospital tank running for 4 months. It has 20 gal, Tunze DOC 9001 skimmer, one box of Marine Pure biomedia balls. No sump...

Hey all, My coraline algae that was once purpleish, is now bleaching white or a faded grey. I'm assuming it's my lighting because parts that have less light are still purple. Behind my anemone when it shrinks up, the coraline is still purple behind it. It started with white spots taking...

Water Changes and Evaporation I see all these people posting about how much water changes they do, some will change as much as 25%/week or more! But most often than not it is a lower percentage than that on a regular monthly basis. I just see this as a major hassle, nutrients being flushed...

Hello, I live in Waterloo, Ontario, Canada and im finding it increasingly more different to source parts. My LFS options are limited and even sourcing online varies heavily in price. Things like converting from USD to CAN dollars and shipping prevents me from buying from vendors like...

Hey everyone, per usual I am here with another noob question. I made saltwater today for a water change but I won't be able to do the water change since it's late. Is it okay to leave it in the Brute Trashcan? I never had stored water, I always immediately used it so first time storing it till...

I've seen some (but never enough) talk regarding GFI's (GFCI's, outlets with two buttons, my personal favorite: 50G, etc) and power strips. If you're new to the hobby (or if you've not thought about it recently), don't forget that water and electricity don't mix! Also remember that at some point...

My RODI unit is showing TDS out equal 1. Is that water ok for a water change? and when should I change those filters?

Hey Everyone, I am need of a RODI and I am not sure which one to pick. Looking for something that is priced just right that is well built. So far I have checked out KoolerMax AR-122, Spectrapure (not sure which model to settle on), and BRS Systems. Are there any other systems you would...

I was wondering if anyone has any good ideas for diffusing the water coming from the return pump. I my tank the water from the return pump causes the sand to constantly blow away from the front glass. I have a single line from the return pump with a fan nozzle and have tried moving it to...

So I currently have a 100 gallon mixed reef aquarium, and I am having a big problem keeping phosphates and nitrates down. I am currently running 1 bag of phosguard with 3 bags of fluval phosphate remover and still can not get the levels down even with water changes. Before 25 gallon water...

Hi Randy, A couple of questions for you: 1. When mixing saltwater, would rapid or violent water movement cause precipitation? Is there an upper bound to the turnover of a mixing container? Typical setups have water being pulled from the bottom of a container, moving through a pump and falling...

what do people think about my tank from 1 to 10. 1 being worst and 10 being best.

I've been thinking of storing my rodi water in a Rubbermaid 32 or so gallon bin. I'd only need about 3-5 gallons of water each week. About how long could I store this before it goes bad? Or would I need something more like a powerhead inside the bin or to seal it?

I have a very basic aquarium set up. It is a 29 gallon Aqueon glass tank, HOB protein skimmer, HOB refugium, HOB filter, couple of cheap power heads, and an AI Hydra 26 HD. I do all of my dosing and topping off manually. I know its a very simple system, but everything is very happy and it works...

I am looking to buy a 10 gallon saltwater tank for Christmas. It will have filters, heater, pumps, live rock, a couple fish, a coral or two, and a deep sand bed. Water changes will be done every week. Because it is so small do I really need to spend all the extra money and buy a protein skimmer...

just picked up a gopro session off craigslist for 100$ was gonna use it for my bike; but it since its waterproof..... (i know i need to clean my tank)

Hey I came across this auto water changer from the UK, It mixes your salt and RO, and then slowly exchanges the old water with the new WHILE mixing them both in the reservoir, which is kind of confusing me. What are your guys' opinion? I put a voter in http://www.reefloat.com/index.php/how-it-works
