cloudy tank

i have a 45 gallon tank with 30lbs of live rock been up for over a year, more now. clean filters regulary and do a 5 gallon water change each weekend. i have a powerhead to move the water around. have 5 fish in the tank with many hermit crabs, snails.
A while back (month or two) i did a 10 gallon water change and not the regular 5 and usually the cloudyness does away after a hour or so but since then i havent gotten the cloudy water to go away. i have cleaned the inside and outside of the tank many times. i just want to get my water clear again. i just today got a seaclone protein skimmer to see if that will help me out but wont know for a while. also upgraded to a hight wattage lighting system but need some help in what to do or buy. if you need any more information please ask ill respond asap.

Is this cloud green or white? It could be your new light system has sparked an algae bloom.

Do you let your newly mixed saltwater sit (with air bubbler or powerhead in it) for 24 hours before adding to the aquarium?

Anything recently caused the sand to be stirred up?

Any recent deaths or dissapearances?

Is it possible you overfed the tank at some point recently?

The protien skimmer should help, but there may be a root cause we can eliminate as well as tackle the effects.

i have a hang on filter that has the sponge, carbon, and biomas filters it is rated for a 50 gallon and my tank is a 45.

its not a green cloudy just isnt clear water like it use to be.
i have changed to ro water month ago(end of feb) and it sits a few hours with salt before i add it to the tank.
the only deaths that have happend was one of my fish i saw was being eaten by a crab and i also had a anenome and it died but i took it out of the tank since it looked sick before it had actually died. but could have done something then. not sure
i have a automatic feeder that feeds the tank 2 times a day. so overfeeding i dont think it would be. i can try to feed them less.
you mentioned a algae bacterial bloom by new lights but i added thoes after it had happend. they are brand new bulbs as well.
what would help get rid of a algae bloom? i will try it.
anyone got any help for me??????

A) When you do a water change, mix up the salt the day before and let the water sit overnight with a power head or an air stone in it. When you pour the water into the tank, take care not to pour in the last bit with the bits of precipitate in it. I don't think this is your major problem, just a tip.

B) If you can adjust your automatic feeder, move it to the minimal settings it will still funciton on. Unless you have a delicate species in there that needs frequent feedings, feeding as little as 3-4 times a week is good for the tank. (Tangs and some other Herbavores will benifit from constant access to real seaweed, but they don't need frequent flake additions.) How long have you been using an automatic feeder?

C) The timing of those deaths in relation to the appearance of the cloudy water could be important.

D) If you don't have any water test kits, I would suggest you purchase some. Nitrate, Nitrite, Ammonia, and pH are the essential ones, along with a refractometer or a hydrometer to track salinity. If you've still got money left, a Phosphate test would be useful in this situation.

I'm betting your problem is excess nutrients. Many organisims in the water are feeding off the excess nutrients and multiplying in the water. A good microscope or a cheap nitrate test kit will likely confirm this. That automatic feeder is dumping in an unknown quantity of food twice a day, and you have no protien skimmer to remove the excess nutirents. Reducing food input and increasing nutrient export should solve this problem.

Ways to export nutrients:
Grow Xenia or seaweed (macroalgae) under bright lights. Trim them regularly, removing the trimmings from the system.
Run a good skimmer.
Perform frequent water changes.

Just wanted to add that flake is notorious for adding po4 to your tank which will lead to algae problems quickly if even slightly overfed.

I’d use frozen foods the majority of the time using flakes very sparingly. Unfortunately you can’t keep using your automatic feeder but IMO they do not belong on SW tanks in the first place since excess/unmonitored feedings can get you into trouble quickly.

Personally I like Marine Cuisine Frozen which is a good balanced diet and vitamin supplemented. Your lfs should stock it in their freezer.

I’d thaw the frozen in a small cup of tank water, and then drain the liquid that is packaged with it to keep po4 down. (You can use a sieve or a paper towel)

I use Kent Garlic Extreme, Selcon, & Zoe to help boost their immune. (I soak all my frozen in this for 30+ minutes)

Feeding every other day is best and only what fish consume in less then 5 minutes. If it not consumed in 5 minutes then reduce feedings slightly. If consumed in less then 30 seconds increase slightly with a second feeding the same day a couple of hours later.

Hara’s 10 Step Plan for Nuisance Algae Control should be helpful as well.

I'm not so sure they belong on FW tanks either. Might be nice alternative to letting your friend massively overfeed while you're on vacation, but on a regular basis it just either somewhat overfeeds or clogs when you're not paying attention to it. (Some models are better than others, but usually flake sitting in a humid enviroment falling down a chute is a recipe for a clogged chute.)

They don't belong on any tank. Feeders like that are bacterial infections waiting to happen. 8O

I admit when I was single I did use them on my brackish tanks only when traveling out of town for 7+ days. I programmed mine to feed pellets every other day to my 7 large cichlids and it was about half the amount I would feed if I was there. I probably should have just asked a friend to do it but most of the time my travel was short notice (worked in IT field) and the auto-feeder was easy. I never used them if I was there and they do work most of the time IME.

I agree also that with SW in particular due to the more “pure” conditions that the use of an auto-feeder should be avoided completely.

IMO for FW/Brackish I would only use in emergencies if the fish can't be fed by a friend and if gone for more then 7 days and the use of floating pellets is far better then flake since as dskidmore stated they do easily clog.

Isn't that part of the fun, feeding and watching them?
I need suggestions for frozen foods, to use after I get rid of the new big container of flake (since that seems to be a semi "no-no").
On food, there are a ton of different frozen foods, from making your own to buying, what is the best/most popular/most nutritious? And where can I get it?
I don't like the gel based, since it sinks straight to the bottom (my fish lose track of it when it is on the substrate, my bristleworms and two shrimp love it.
I just got a bottle of ZOE, Selcore, Garlic Plus, soak the brine shrimp in those (and tank water), and feed the fish, but it doesn't seem like they eat a lot of that, the clown likes to eat it and spit it right back out...

Brine shrimp have very little nutritional value to fish and should be avoided IMO. Occasionally you could feed live brine shrimp that have been swimming in Selcon but I would do that sparingly as well.

Flake isn’t necessarily a complete “no-no” since feeding a varied diet is as important as what you feed.

Personally I like Marine Cuisine Frozen the most but I also feed bio-aquatics, Ocean Nutrition Prime Reef Frozen,
nori daily to my Yellow Tang, & minimal flake once a week.

Most good lfs will stock all these and if they don't you can ask them to order it.
