im in the process of planning an nps/filter feeder tank, and the part im currently stuck on is choosing display tank size. the "bigger is better" rule may not be entirely true in a nps system, so id like to figure out what the general feeding and maintenance costs are so i can choose the largest...

I'm planning on building a new system soon which will inhabit several nps corals and filter feeders. I cant decide on a deep or shallow sand bed. Ive read that a dsb can be a food source but ive also read they can become phosphate saturated over time and can become a problem. do i go with a...

so ive become interested in keeping catsharks but have found issues on the warm water species. 1st issue is most get to be over 3' and 2nd issue is the expense of keeping a 500g aquarium warm. so i began thinking about subtropical catsharks. many species dont get bigger than 2' and prefer...

im thinking about removing my dsb. it is about 5 years old and showing major signs of old tank syndrome. i feed 3x a week with weekly water changes but still have wall to wall algae and suffering corals. i blame this on the reading of .15 ppm phosphate i got from inside the sand bed (syringe)...

so my tank has been having alot of issues over the past year. i think it has old tank syndrome. one of which is the wall to wall algae i have. i tested phosphate in the water column and got 0.03 ppm but i asumed that was because the algae is eating it up. so i stuck a syringe in the 3" sand bed...

i need help building artificial mangrove roots like seen in this picture. i want them to be roughly 24". what products, techniques, etc? i need them to be 100% reef safe and permanent. any suggestions are greatly appreciated. i been to all corners of the internet looking for manufactured ones i...

bought this paly about a month ago and i forget what it was called. the color has faded alot but but they are multiplying. i moved it lower in the tank hopefuly it starts coming back.

i am having hell trying to raise ph to 8.3. ive tried dosing alk to weekly water changes with top quality salt and it seems to want to stay at 8-8.07. ive even put an airstone fed from fresh outside air to keep co2 down. the swing is very minimal it never goes below 7.95. could old sand and rock...

im using an elos magnesium test kit and have lately been confused with my inconsistent results. so i just did 3 back to back tests and my readings were 1350, 1200, 1250... anyone else had issues with inconsistency? could my reagents have expired? i purchased them a little over a year ago

came home today to see my cucumber i purchased last week was missing parts of his flesh! his tank mates are brittle star, 6line wrasse, one small hermit and some trochus snails....might be a pistol shrimp in there but havent seen it in a few weeks. i quarantined him in a bag until i can diagnose...

im looking into creating a lower maintenance tank housing only soft and polyp corals with a few lps. does anyone have experience with kalkwasser? would it be considered easier than 2 part dosing and can it meet the demands of a non sps reef?

ive always used 2 part cal & alk supplement but as my life gets busier i am trying to cut down on maintenance. ideally i would add a one part supplement to my auto top off basin and let it dose for me. auto dosers seem to be too pricy especially for a 2 part one. i am only keeping some lps and...

if anyone has ever seen pictures of real mangrove roots they can agree the ornaments found on the market look nothing like the real thing. does anyone know how i could make some of my own? they do not require alot of detail but color and shape need to be correct.

i am trying to replicate a mangrove lagoon aquascape and i need to come up with a way to make wood sticks reef safe as i have heard even driftwood will lower ph. i do not want to use any of the synthetic wood ornaments i have seen available on the market as they are all in the form of small tree...

have been tryin to raise magnesium in my tank over the past week adding no more than 80-100 ppm per day starting at 950 ppm now standing at 1300. (100 ml per dose) my anemone now has a twisted foot and some polyp corals won't open. all parameters seem good. what can i do?

have a 30 gal tank with a 150w 14k bulb MH pendant running 7 hours a day. green bulb nem thrives at top of tank while corals will only survive in bottom half. if i prolong daylight hours can i run a 20k bulb (for aesthetic reasons mostly)? anyone have experience with nems under these?

just tested parameters directly after water change; magnesium 900 ph 8.2 alk 6dkh. what causes low magnesium levels?? how do i resolve the problem.

does anyone have experience with auto dosing 2 part c-balance? i am out of town 3 days a week so i am not able to maintain manual dosing. do dosing pumps work for this? if so which ones are good?

about 10 days ago i bought a few corals from the store along with some echotech coral glue and glued them and some other pre existing corals to rock structures. all my corals didnt like it too much as i was rumaging around the tank for an hour.. a couple days later they started to open up again...

ever since i installed my sump/refugium the coraline in my display has all almost completely died off while it grows in the refugium. this is not much of a suprise since my fuge light is on 24/7 and my display light is only on about 9 hours of the day. i just thought it would sort of balance...

My over flow has the baffle so it shouldnt lose syphon but my concern is a snail crawling inside the tube and restricting water flow. The water in the return chamber of my sump will go down causing the auto top off to kick in, filling my tank with fresh water while overflowing until the water...

I just set up my refugium sump and i need to know whether to go with miracle mud or deep sand bed? I only have a 7 inch deep fuge so i really only have about 3 inches room for substrate. What are the pros and cons of both? My main focus for the refugium is to reduce algae in the display

I just setup my refugium for my 25g reef tank and i need to know what to stock it with primarily for algae control in the display

I have a 200 gph nano over flow that i just setup and am trying to get rid of the gurgling noise. I currently have a short stub of pipe with foam around the top which is what the overflow comes with and it helps but isnt great. I dont have room to fit a durso stand pipe or another bulkhead. Any...

In my return line there is t'd off valved line coming back to the sump so i can control how much water goes into the display without hurting the pump. I am having an impossible time getting the water being pumped out of the sump balanced with the water coming in via overflow. Any tips or...
