water

So I started a new biocube 32 about a week and a half ago. I was so lazy to mix salt water and I found this water (Imagitarium Pacific Ocean Water) at Petco. I tested my levels today ammonia was 0, nitrite was 0, and nitrate was 2. Ummm... so is my tank completely cycled. I’ve never used this...

So I have been testing my water Everyday and my parameters are 420 Calcium 8.5 to 9.3 Kh 1200 Magnesium Started adding Kent’s magnesium for 3 days and can not get it to Raise. Any Advice ? Would be much appreciated have a Kung Pow Monti on the way and would like it to be around 1300. Also...

So here's a pretty dumb question - I have a 120 gallon aquarium I'm starting up. I'd like to get the cycle moving along as I get all the equipment and hardware together, but obviously that volume of water is going to be a bit of a pain to acquire. I could call my mom and pop LFS or try to make...

Soooo. Been using some scrap supplies and a random turtle tank I had laying around to do a new project. I build custom bioactive vivariums for tropical reptiles on the side, so I grow most of the plants I use in my green house. I’ve been vending through a buddy’s booth at the reptile shows, so...

Is it healthy to drink 0 TDS water as my only drinking, cooking water source? Or do I need the minerals left over. Our tap water TDS is 450 and even through the fridge filter, it is still 400. We even got an Aquasana whole house filter with softener and pre/post filter and it still shows...

The new house my wife and I are buying has a well and iv just learned that it's best to run rodi units up around 60-90 psi. I don't know the pressure but I would assume the well pump has a 30/50 switch. So I've looked into the Vertex Puratek deluxe 100 Or The BRS 4 stage with a booster pump...

So I know this is a noob question, but I have a special water source where my tap gets filtered before it comes out, so no chlorine in the water and such. TDS is 200 due to elevated calcium and such. I was always told that you should always use RO water, but I was never told why. All I know that...

Hello, I am trying to find out how much Calcium, DKH, and Magnesium is being used in a day in my reef tank. I don't currently have a 2 part dosing system to keep the levels right and I am using 2 different things do dose and it is been working, but I need help with the calculations. I might...

Hello, I am wondering if a protein skimmer takes Calcium, DKH, and Magnesium out of a reef tank? I am trying to see if there is a way to keep these things in the water without having to dose so much, as this stuff can get expensive quickly.

Is it because water parameters are off, Calcium, DKH, Magnesium, or maybe to much salt?

who here disconnects their di and makes drinking water with the first filters? Does the waste waster outweigh the convenience ?

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?
