high

Hey guys, so I recently moved my tank. There was a small leak in my skimmer so I had to take it all down to clean up the mess that was on the floor. In doing so I decided to rearrange my live rock, and I added a bottom to the tank, I hate BB. I probably lost about 30% of the water maybe 40% when...

I setup a 72 gallon tank with a 20 gallon sump about 6 months ago and since about week 2 I have had high nitrates! How do I lower these?! I have a reef octopus nwb110 skimming wet, use 0tds RODI water for water changes and top off and I do 20% water changes weekly siphon the sand bed during...

so I'm new here and i've had my 90 gal reef with a 20 gal custom sump up and running since last year oct .i've been running npx biopellets since 31st oct this year and I'm noticing brown algae on the sandbed.the pellets are running in a reactor and are being fed into the inlet of the BM nac...

Hi guys!! So I need some help. I just set up a 20 gal high tank on monday, 8/26. i have about 20-25 lbs of dry rock in the tank. I put i a piece of cocktail shrimp in on monday as well to help kickstart the cycle. I also have been putting in a little less then an 1/8 teaspoon of sentry saltwater...

Hi guys, I have a 100 gallon rimless tank. I also hooked up the tunze ato. It seems like my water level is a bit high. How can I lower the water level in the display tank without triggering the ato? Maybe shut the ato off and then take water out and then turn it back on? I don't want to over...

Ok... first of all my tank. 4 years old. Includes one spot foxface, small blue hippo, sailfin tang, lawnmower blenny, 2 clowns, 2 emerald crabs, a few blue leg and scarlet hermits, some snails, star, ricordea yuma, tube coral, zoas, candy cane, couple of brains. 75gal 6 feet long with 365w t-5s...

My 60 gallon tank has been cycling for about a week now. I used bio spira and have not done a water change yet. My ammonia, Nitrites and PH are all good but for some reason my nitrates are around 10-20ppm what can i do to help them lower down i also have about 55lbs of live rock and 30lbs of LS...

So I think I got some bad advice from my lfs..... I was told I did not need to worry about dosing Ca and alk until I got some corals that used it in my tank. Well I had not tested for it thinking it was not important yet.....bad move I think. My ca is 220 and my dkh is 14. I have started dosing...

What does this mean? And, more importantly, what can I do about it? My alkalinity tests are off the chart (higher than 3.6 meq/L), but my pH is frighteningly low (around 7.7 or 7.8). I don't have a calcium test, my tank is 20 gallons, very new, still cycling, cuc and live rock in it right now...

so I tested my water, and my pH was pretty high. like 8.7 high. Good news is that my ammonia, nitrites, and nitrates are all at or near 0 YAY aaaand back to problems. I'm guessing it went up from when I did a massive water change (practically all the water) after an incident with soap...

My best friend is thinking about getting into the aquarium hobby again. She wants to do freshwater and has a specific place to put a tank in her living room. It will need to be an extra-high or column tank with a small footprint. Bless her heart, bow-fronts won't work because make her sick...

Hi, Whilst setting up my marine tank I noticed a very sudden drop in PH (took the test at night) so i put some buffer in but it seemed to do nothing to the PH. I put more and more in over the course of a few hours and left it at that. It has now stabilised, however I have just bought a dKH test...

I know calcium in a reef tank should be around 450, 440 or so but i sometimes here people say they are at 500 or so... can anyone tell me what would happen if calcium is to high??? i have had mine up there before and i just stopped dosing until it dropped but what are the dangers if it goes up...

I have been dosing pickling lime in my top off water. Has gotten calcium levels where i want them, but ph is up to 8.6 and nitrates are up to 20. I am addressing the nitrates, but how do I manage the ph downward? 90 gallon fowlr display with 40 gallon sump/refugium.

Hey guys I live in Lafayette and started a reef tank back when cool corals was around. My wife is pregnant and I've really just lost interest in my tank so we need the room. I know it's bad to jump on forums just to sell stuff but not sure what to do no luck with paper or craigslist. It's a...

Okay, so like the title says, I'm wondering about the possibility of soft corals with this setup. It's a 90g high, I would say from sand bed to water level is 22'', sand bed to light source in the hood is more like 29'' or 30''. Also, my rocks rise up to about 6-8'' from the surface in some...
