Hey everyone, I've had my 29g biocube (standard) setup for about a month now (live rock and live sand). I've cycled and dropped two damsels in. Once I introduced the damsels I began to see a lot of brown diatom algae on my sand bed and live rock. Some advice from here said that's pretty...

I've been using the "tap water filter" made by API for the last few years, and just found out tonight while looking for replacement cartridges that the darn thing has been discontinued!! So now the hunt is on for a new unit. I'd really prefer something inexpensive that'll get the job done. I've...

Before I go all out and give my lfs (chain of stores in the uk called dobbies) a piece of my mind. I need to just ask and confirm. "Should Ro water bought from a store have nitrates in it?" I ask because I have been fighting nitrates bad recently. We're talking 60-80's (and my refugium was @...

I tested my RO water today and it now has nitrate levels of .25ppm does this mean the membrane need to be replaced or is it something else

What does everyone use for RO storage/ salt water mixing? I am undertaking a massive project to move my sump and everything into the basement below my tank, and I want to have a large tank for RO storage.

Can i use bottled spring water for my tank if i run it through a brita filter? Id rather not pay for RO or buy a RO Machine. What are some alternatives? will i notice any certain differences if i use distilled water instead of RO?

Good morning from snowy Post Falls, Idaho! Quick question for you guys. I buy "RO/DI" water from my local SFS in town, and, wondering if it really does past the test...mostly because I have allot of algae bloom going on. If you read my "new guy here" thread, you can see my tank is about a...

Hi, I am looking for some help, I am fairly new to reef keeping and have had my aqua reef 300 for around 6 months. I recently decided to invest in a RO Filter, I have bought a TMC 50 and a 200 litre water butt heater and had a spare korrila 1600 power head so stuck that in to circulate. Just so...

Enter your 10% reef club discount code in the “view cart” section above Paypal checkout logo. All reverse osmosis systems should get the filters replaced at least annually. If you have poor water to begin with, you may need to change out more often. Our high quality FilmTec membrane will last...

Ok... I have a blessing and a dilemma I am being given an entire well established (2year) flourishing reef tank this weekend... unfortunately it is the inhabitants ONLY... no tank comes with it, so I must find a way to convert my current FOWLR tank into something suitable for the newcomers...

Hey all my RO isn't set up yet but I have some semi damp Rick I feel the need to get in some FSW to start curing it. Can I just use my drinking water filter? I would be doing top offs with the RO since it will be installed in a week or so.

Started up my 14g biocube 5 nights ago. 10lbs LS, 12 lbs cured LR, and saltwater from LFS. Yesterday I woke up and noticed a slight brown color to some of by LR, got home from work and it was a little worse, today even more so. I'm hoping is just the "diatom bloom". Tested water yesterday...

Hi I have a ten gallon nano and it seems like my salinity levels keep getting up to 1.026. It seems like I have to keep adding RO water to keep it in the norm, is this normal? Is there anything I should be doing different?

I have access to bottled RO water for drinking can i use this in my tank?

Does one need to heat their RO water? If theyr doing 10-20% water change that is? Is the change in temp a huge stress or no?

Hi guys Just tested the RO (not rodi) water I buy from LFS, it has a nitrate reading of between 60-80ppm using an api master test kit. I don't know much about RO water, is it meant to remove nitrates? I've been doing weekly water changes and my nitrates have always been around this level, now I...

Is using just RO water fine compared to a RO/DI unit for my 10 gallon soon to be reef tank. :help:

Hello, I am going on vacation this Sunday for 1 week and no one will be here to maintain my 10 gallon reef. I am looking for a nice auto top off system. I bought a tsunami ATO system but the water drops too low before the pump kicks in, keep in mind this is a 10 gallon with no sump, or at least...
