I just replaced my old 90-gallon legacy tank with a modern standard 90. It is up and running but I am having an issue with the noise from the overflow. My old tank used a durso standpipe and was almost silent. This tank has a slotted pipe with a foam cover over it and a float that sits inside...

I have had my durso in the tank for over 2 years. Never had any issues with it. Now, the past few weeks, it is making some strange noises. Not like the flushing or gurgling you would expect, but a sound like someone tapping a kettle drum with the reverbrations and everything. It is really LOUD...

or how to treat it. It wasn't there last week and a few days ago it was less than half the size it is now.

I just found these on the back glass of my 90-gallon reef tank. The colors are a dark red with light colored bumps. At first I thought it to be a mojano, then I thought it might be a ricordia. Now I'm just not sure. There are several of them growing back there with sizes ranging from 1/8" to...

I spent a few weeks building a custom LED light fixture and a new canopy for my legacy 90-gallon tank. This is the driver box I made to make the lights work.

When I put my tank together I intentionally put coraline algae into it. I like the way it looks on the rocks. I just hate the way it covers the glass and everything else. Is there a way to get rid of coralline without completely tearing down the tank and starting over?

I installed a new Eshopps PSK-75H into my tank 3 days ago. It is working and removing proteins extremely well. However, my tank is now full of microbubbles coming from the foam filter. I have removed the foam and squeezed it under water 3 times to remove the bubbles in the foam but they return...

I have a 48" 760w Odyssea light system with 2-250w metal halides and 4-54w actinics. 1 pair of the actinics has quit working. I took the light fixture apart (whew, THAT was an adventure) and found that 1 of the electronic ballasts had blown, letting all the black goop out of the components...

Last week I took my skimmer apart to clean it and reassembled it. I put it back in the sump and plugged it in and got a huge surprise. The skimmer started overflowing immediately, about 1/2 quart per minute. I figured it just needed adjusting so I attempted to tweak the gate valve to get it back...

I have been away from my tank for about a week. Last night I came home and found this green, stringy, slimy stuff growing on the sand and glass. It isn't hair algae, looking more like cyano than anything else, but I have never heard of green cyano. My pics arent very clear but I think you can...

I have an emerald crab that has gone predator on me. He has killed my Caribbean Pygmy Angel and my Sunrise Dottyback is missing. I saw both last night swimming energetically and I saw the angel this morning. Tonight I fed the fish and immediately missed both of them. Looking around I found a...

It has been quite a while since I updated my thread. So long that I cant post any more replies. Sorry folks, but I injured my shoulder and with surgery this kinda took a back seat. Anyway, after the seemingly eternal fishless cycle I finally have my tank up and running. I have 7 fish in it so...

I am ready to put my first fish in my new saltwater tank. I have been shopping at 3 different stores and every time they asked what I have in the tank. When I tell them I have nothing and I cycled fishless they look at me like I grew another head. I explained the process and they couldnt believe...

Is it possible for a cycle to stall? :confused: I ask because when I dose ammonia to 2.0ppm it disappears or almost disappears by the next day. The Nitrites go to 2.0 and stays there for several days if I dont dose ammonia. After 3-5 days the Nitrites disappear. If I add even 1 ml ammonia the...

I read that you can raise the KH in a tank using a sodium carbonate solution. You can make the sodium carbonate from baking soda by placing it in an oven at 300 degrees for 1 hour. This supposedly removes the extra oxygen molecule and causes the powder to give off CO2. Since my wife keeps...

Day 39 of the seemingly eternal cycle and the tests appear to be doing ok. The only things I noticed this week is the KH has dropped significantly in the past 2 weeks and my Nitrites seems to be stable at 2.0. Test results today: Ammonia - 0 (I dosed to to 2 ml yesterday) Nitrites - 2.0...

I have 3 circulation pumps in my 90 gallon tank. One of them absolutely refuses to stay in place and migrates towards the back of the tank. I have let up on the tension from the cord and made sure the suction cups were clean when I moved it back yesterday, but today I found it almost to the back...

There is a new TV show coming on National Geographic Wild, premeiring next Saturday at 10pm. Hopefully they will show better husbandry than 'Tanked'. Fishtank Kings: A New Nat Geo TV Show (Updated with Press Release) — Advanced Aquarist | Aquarist Magazine and Blog

I am currently at day 20 of my fishless cycle. At day 15 I started finding life in the tank. :dance: I found some stomatella snails, some tiny red feather dusters, an aiptasia (now deceased), a couple small white feathery things too small to take a pic of (possibly anemones, but they dont seem...

I've been out of town for a week or so while my tank is cycling. My son took good care of the tank. I found some things growing including some small anemones (I hope it isnt aiptasia, but still checking), some red and clear colored "bugs" and this thing in a brown shell that crawls like a snail...

Looks gray and hairy... :confused:

I have a set of hanging lights over my saltwater tank. Now the wife is complaining that they are too bright for the room and wants me to come up with something decent looking to block the light from illuminating the whole living room. My light fixture contains 2- 250w metal halides, 4- 54w...

If you have been following my threads you know I just started my first saltwater 90 gallon tank. On Monday I got the water in the tank with a salinity of 1.0245. Tuesday I dosed the tank to 4ppm ammonia. I have had some evaporation and replaced the water lost with RO/DI water. I checked the tank...

I FINALLY have my first saltwater tank full of water and pumps running. :dance: I am starting a fishless cycle and currently have 100 pounds of dry rock in the tank. I am in the process of dosing the ammonia to 4ppm (a little at a time so I dont put too much in). I want to add some live rock...

I have a corner overflow in the saltwater tank I am setting up. I finally got the plumbing and all worked out. The return pump is a little noisier than I would have liked so I am sure a new one is in the not-too-distant future. :whistle: The biggest issue is the noise from the overflow. My...
