I am looking at buying a pre existing 135 gallon tank. Does anyone have experience on doing this or can you guys give me advice on how to do this? How would one transfer everything? Thank you!

All of a sudden my long nose hawkfish is acting weird. Afraid he is dying. Had 2 other fish die but think it was because of the store I bought them from. The hawkfish I have had for awhile. Water parameters are fine. Tank is established 30 gallon with coral. He isn't moving much and when he does...

Hi everyone, looking for some information on a very contentious issue. I have been dealing with a very bad algae outbreak for the last few weeks and have been doing small 5-10% daily water changes syphoning the sand. Now the sand is less than an inch at most places and down to the glass in...

20L, 60lbs of live rock, 4-6" of coarse and fine sand mixture. Cheap filter for up-to 30 gallons that has no media except the sock I use when I do water changes. Only moves water. 1 pump to create turbulence, turned off at night. Cheap LED lighting with sunlight and actinic strips. Cleanup...

Hi I have had my tank for about 6 months now. I have a happy clown, damsel, and goby. I was wondering if it would be possible to add some dead rock. I have been thinking that It seems a little barren. I know I can't add live rock but what about dead rock? Thank for any help I get...

Hello everyone! It has been a while since my husband and I have been around. In 2010 we set up our 125 gallons tank. It was stocked with LR, DSB, Corals and Fish. It ran a while and crashed, leaving only my little clownfish and 3 corals (Brain, Hammer and Torch) alive. They were in a ten gallon...

Newbie with a substrate question. Will a white substrate of an established tank remain white, or do you have to occasionally stir the sand bed?

Ok so I am very new at this so it might be a stupid question. I bought an already established 29 gallon biocube. It already has live rock and sand, corals, inverts, and fish. I sold two of the corals out if it to make room for some new stuff. The corals I removed were attached to about 3 lbs of...

I've read the previous comment(s) about adding live sand to an established reef tank but nothing regarding solutions. However, I made the mistake of doing this but only about 2 lbs of the LS. I noticed an immediate change is parameters. In my 55 gal. I've managed to get the pH back to about 8.2...

hello, I have not been able to find an answer to my question, or if i have to worry at all about my question. i applogize if this is addressed already. I have a 125 gallon saltwater. FOWLR. tank was set up in 2009 and ran for 2 years without any major problems. i had about 5 fish total with...

I believe my sand bed is not adequate as it is only about a 1/2 deep. I was hoping to add some more sand. My tank has been established for approximately 7 months. I don't want to wreck the work that has already been established. Any thoughts? Equipment: 30 Gallon Long, 30 lbs of live rock, 25...

thanks ahead of time for the help. i have a tank that's about 2 years old and recently i've had an outbreak of algae and masive amouts of cyanobacteria growth, taking over even the glass walls massive. I have a 3.5 inch crushed aragonite sand bed. I'm wondering if it could be something with the...

After my pump comes in and I get a sump added I am going to replace my sand bed. Well, I have to take all the sand and rock out of the DT to drill it, So it seems like as good a time as any to replace the majority of the sand. After this is done I think I may try a quadricolor. The new sand...
