water quality

So I am new and I am sure this question has been asked many times. Today I tested my water and everything looks good. Ammonia and Nitrite are at 0, Ph 8.2 and Alkalinity is at 10 dKh. My salinity is at 1.024. The problem is the nitrates. I measured a 20 ppm so I changed 30 gallons of water...

i have a 55 gallon mixed tank that had been up and running for about 6 months or so w/o significant issue. I have been battling high nitrates, but everything (fish and coral) has seemed happy. In a foolish attempt to lower my nitrates I did about a 50% water change and it killed 5 snails, a...

I have a 55 gallon tank with a 20 or so gallon sump. I have a protein skimmer rated for 120g tank, dragons breath macro algae, 2 4" filter socks I change twice weekly in addition to 20gallon water changes weekly. I have a moderate amount of rock and I also use xport bio and xport no3. I have...

Hi, I am in need of a well priced RODI. I asked already in the New to SW section but I had no idea this category existed. If there's any deals/coupons currently going on out there I would love to know. Aiming for 4-5stage RODI that can handle silicates and chlorinates/chloramines. I really...

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'm a novice with this hobby but have heard the importance of good water quality. So I decided to get a RO/DI system. I am on a tight budget and found this system on amazon : Aquarium Reef Reverse Osmosis water filter 6 stage RO/DI SYSTEM 75 GPD USA...

I've been doing my cycle for a week or 2, a had a diatom bloom while back. I used LR etc. and live bacteria added to water. However, I noticed my Nitrite AND nitrate levels are rising at the same time. Is that normal? my LR ratio is 80% Live 20% dead I have some green algae growing few days...

I have feather dusters on my LR and they've opened up for a few days. Does that mean my water quality is good enough to house fish (damsel fish like clown fish, hardy things) and add CUC. Of course I'm going to do 10% water change b4 adding.
