I have about 90lbs of live rock and 40lbs of live sand in my 90g FOWLR. I recently noticed a few aptasia anemones growing in my tank on my live rock yet my nitrate test kit says my nitrate is at 30-40ppm...is this possible or is my test kit likely wrong? I thought anemones needed great water...

Anyone ever have problems with Emerlad Crabs and Cleaner Shrimp co-existing in the same tank? Have a 90g FOWLR. Just put an order from saltwaterfish.com and qualified for a free item. I added 3 emerald crabs and didn't think about compatability with the shrimp on the same order. Let me know asap...

I have had a salt water for over 3 years. I recently moved and took the opportunity to change my 90 gallon FO tank to a FOWLR. I took all the bio balls out of my wet dry and now I have about 90 lbs of live rock and 40 lbs of live sand. My water parameters are as follows: SG: 1.023 pH: 8.2 Temp...

If you bought a refractometer and made a change to your salt level too quickly, how long would it take to kill fish? I did this and found my hydrometer pretty far off therefore salt level too low and I think I tried to raise it too quickly because I have lost a fish and a shrimp. The fish that...

I have read a few articles suggesting that you place PVC pipe under your live rock and then use your substrate to cover it. They list several benefits but I was thinking of one negative that was never mentioned...I have read that aquariums that use plenums to trap nitrogen under a DSB must...

I recently moved and am taking the opportunity to start over on my saltwater tank. I kept a healthy fish only tank but plan to make a few changes in the setup this time, including using live rock. Will I need to upgrade my lighting to keep coralline alive? I would like it to grow and keep the...

I am moving and starting my tank over. I plan on using RO/DI water so it will take me a few days to make 90 gallons plus the extra required to run through my filter system. Once I add the salt and get the salinity where it needs to be, I would like to add live rock and live sand. I have heard...

I recently purchased a home and will be relocating my 90g FO with built in overflow. Since I will be resetting the system and starting over, I am taking the opportunity to change any aspects of my setup that I should. I am will be using RODI water this time rather than tap like last time. Here...

What are the advantages / disadvantages of each? I am not sure which to setup in my system. I do not have a need for pods at this point but am wondering if denitrators actually work and how much maintanence is required and anything else I should know.

If you got one do over in your current setup, what would it be? Everyone has something about their system that if they started over from scratch, they would change. What is it? This could become a great informational thread for someone getting ready to start a new reef if people post to it enough.

Does having a glass cover on your tank have any reprecussions as far as light goes? Does it decrease the PARs that make it to the water? Do people run their reefs with or without tops? What are the affects on temperature? Does keeping a tank covered keep it cooler or hotter? No cover means more...

I noticed tonight that there are very small white dots on my glass that seem to be moving. A picture would not even be possible they are so small but they are moving so I think they are alive. Any ideas what these are? Please tell me these are just some kind of harmless pods and not ich or...

What are the trade-offs of using 20,000K metal halide bulbs vs. 10,000K bulbs and supplementing the whiter light with actinic PCs, VHOs or T5s. Is it worth the extra cost of having the supplemental lights? Or does a 20,000K get the job done?

Trying to decide on lighting for a 36" 40 gallon reef tank. The tank is only 16" deep. I know a guy that makes custom hoods and will basically make anything I want. What are peoples thoughts on 1 250W HQI bulb vs. 2 150W HQI bulbs? Will one bulb cover the full 36 inches? Will it cost more to...

Anyone have/use the new Current Outer Orbit fixtures. They claim to have a revolutionary internal ballast that uses a microchip and is able to operate HQI, PC and lunar on the same internal ballast. Curious to know your thoughts on perfromance and temperature effect on water.

This is also posted in the equipment forum... Thinking of starting a reef tank in a 40 Breeder. Not 100% sure on lighting yet but was thinking the new coralife aqualight pro that has a 10,000K HQI, Actinic PCs and Lunar lights all in the same hood. I live in an apartment so hanging is not an...

My current fish only tank is pre-drilled and has an overflow that flows down to my sump. I am thinking of starting a new reef tank in a 40 breeder with live rock and the AquaC Remora skimmer (which I have heard is great). The one I want to get is powered by a Maxi-Jet 1200 and would have the pre...
