I am breaking down my tank for a home remodel, traded in the fish already, but have a ton of live rock and very healthy GPS. I was thinking it may work to put it in a rubber trash can in its own water, run a powerhead in it, and call it a day. I could give it ambient light and do water changes...

I have a 29g FOWLR tank and the GSP is nearly out of control. The tank has been super stable with very few casualties, but I just added a couple small yellow gobies and I worry about bioload. The tank current occupants include: >Bi-color dwarf angel >Royal Gramma >Benghali Cardinal >Six line...

I have a well established 29g FOWLR tank that has healthy GSP growth on most of the rock. I did a water change 4 days ago as I've done every 2 weeks for years. The tank is VERY stable - at least until this morning when I saw a blizzard of red spores (they were tiny red dots) that had consumed...

Just installed my first GFO reactor today. You may have helped me with that purchase if you were posting on my question about algae. Flow rate is supposed to be 20 gph but instructions say to tumble the media gently to avoid it being pulverized. I am using PhosBan granules. Tumbling gently...

I moved an 8 yr old 110 gal FOWLR tank into a smaller 29 gal environment and shortly after this, found algae growing on my urchins and much of the LR. Its growing quickly. I've never had this problem before, and not sure how it started (maybe because I no longer have a refugium). In any event...

My urchins are several years old. About 4 months ago I moved them from a 100g to 28g tank, where everything else seems to be growing fine. I recently noticed they were growing green fur on their needles. Looks like algae but....seems to be growing out of the needles. Has anybody observed...

We've sold our house and I am facing the move of my 100g FOWLR tank with a 20g refugium to a rental down the street. I am NOT looking forward to this. I've read that disturbing live sand could set off some type of toxic discharge. Any truth to this? How do I deal with this during the move...

I just moved to an LED light system and looking for ways to control algae growth. I thought I had enough snails but a friend said he knows somebody with a similar tank that has 10X my quantity. Made me wonder, what IS the right number of snails? My tank is 100g and is FOWLR. Thanks for...

My FOWLR (with some mushrooms) tank is 110 gal and last I tried LED it did not penetrate to the sand. I understand technology has improved. I currently have 4 T5 each of actinic and 10,000K white at 39W each - 8 total bulbs. I've replaced them each year and would love to make the move to LED...

My tank is FOWLR and a few mushrooms. Its 110gal with a fuge of about 15-20 g. My livestock is very healthy. I've lost one fish (a new one that just did not make the food), in about 2 years. I do water changes (15-20%) every other week. I use RO water. I dont have much of an algae problem...

I have a T5 HO system running on my DT - 4 bulbs bright and 4 actinic. I've changed bulbs every year but find the range of options confusing. I've given up on high end corals but have a series of very healthy mushrooms and small colony of zoos that I would like to see flourish. Can you tell...

The setup is over 6 years old. The refugium is glass, made by Catalina, with 3 compartments for sump, biomaterial, and return pump. I put a pad underneath it when I originally installed it. The pad is very moist and I can see the laminate underneath (the bottom of the unit), is so wet that it...

a bloom came off - a mushroom cap - and I've been trying to get it re-attached to a rock. it floats off most the time. there is no stalk. can it be saved????

There are several attractive species on this site, and I would like to add 3-4 to my community tank. I see purple and red varieties. The site suggests they "do well in groups" whatever that means. What do you suggest as the best schooling variety of anthias? Thanks in advance.

Over the years I've spent hundreds (at least not thousands) on corals only to see them pass away. I've tried feeding them with supplements and have concluded I am not cut out for this aspect of the hobby. I am sure my water parameters are not ideal, but my fish seem to like them and I've a...

Am rebooting my tank and want to start fresh with some good schooling species. have some soft corals (shrooms) and would like to expand my coral collection so want fish that will behave and eat the fish food only! appreciate recommendations. current inhabitants include 2 percula, one YT, six...

i had a custom tank stand built about 6 yrs ago for a 110 g tank. i built a refugium into the bottom which ended up with little clearance from the bottom of the DT. Over the years, salt buildup caused some warping of the plywood above the fuge. I glued some plexiglass above the fuge to...

This picks up where "Algae vs Coralline" drops off. Bottom line is my LFS suggests that after 5 yrs with same substrate, that I remove it completely in my FOWLR DT. He suggests the same for the fuge. What got this started was my noticing a large spike in algae growth even though my parameters...

My tank is > 5 yrs old and I have never developed that layer of coraline growth on the back glass. Until recently, i did not really care, but the algae growth is now getting on my nerves. I have to scrap back gobs of it every two weeks and it is choking my GPS, among other things - see pics -...

my setup is about 6 yrs old and i saw something frightening tonight: The DT is 100 gallons with a 20g refuge underneath. The display was custom made by a local craftsman that works for a LFS. The refuge clearance is very small, and the sump sits a few inches under the bottom which holds up...
