Algae Bloom?

Hey all!

This is my first post, since until recently my tank was completely a Malawi hardscape.

Still, I've been a lurker for a long while now. I plan on setting up a planted nano in the near future, and you guys have been invaluable in learning all the dos and donts.

Anyhow, I was hoping to get some advice on what could be causing the murkiness in my water.

I'm just going to cut and paste the relavant info over from my local forum:

_______________

Is it possible to have an algae bloom in the water column (clouding the water with a slight green tinge), but not have any visible algae forming on the surfaces of rocks, glass or substrate?

I've been doing 25% WCs weekly (2x this week). All water added back has been treated with Prime prior to being pumped in to the tank.

Water parameters are all good:



pH: 8.2
Ammonia: 0ppm
Nitrite: 0ppm
Nitrate: 0ppm

The fish all seem happy! I'm just sick of the haze .

I'd thought it might be a bacterial bloom, as I added a doubled the bioload, but its been around for awhile now.

Current stocking:

10 - Melanochromis Auratus
5 - Pseudotropheus sp. "Acei"
3 - Metriaclima sp. "BB Zebra Chilumba"
2 - Synodontis Cats (Not sure which - but for $7ea, I don't think they're anything fancy .

I'm using two Fluval 405s for filtration: One has >[Carbon][Carbon][Biomedia][Biomedia]>, the other has >[Purigen][Biomedia][Biomedia][Filter Floss]>.

I'll be adding a Hydor powerhead (Evolution 750) one UPS drops it off this evening. I've cut back on feeding, but only to 1x daily. I've been feeding a small enough amount that they devour it all in ~30 seconds or less.

Lights are on a timer, and are on from 8am-noon, and from 3pm-8pm.

Any thoughts on what could be going on, and what I should do (if anything?).

Here are some more crappy iPhone pics - this time the haze is not a photoshop added effect





They're huge fans of the camera... They love me... it has nothing to do with food.

They've done a great job at dislodging all of the Java Moss I added... even pulling it when it was tied down. Going to try to tie the stuff down one final time before I give up.

From the front, the tank looks cloudy, but not overly green. Here is a shot from the side:



That, obviously, looks terrible! All advice is welcome. Thanks!

Here's the link to the original thread over on houstonfishbox.com in case anyone cars Tank is a 90g.

Hey, welcome..
That's what we call Green water. They're diatomic algae. They like light so if you leave it off and do a lot of massive water changes, it'll go away. Another option is running a UV sterilizer. That'll kill the diatoms.

They are harmless to your fish.

Thanks

Hope the fish like the dark.

Can I also try utlizing a diatom filter? Are there diatom "bags" that I could put in the fluval canister's compartments?

Thanks again!

I good UV sterilizer will clear it up in a day (or a few). Take a look at this site:

I got a couple of different UV sterilizers from them and they have great customer service.

Just set up a new tank three weeks ago. It was doing great until I added some aquarium salt. Within 24 hours the water was cloudy. Now I can't see across the width of my aquarium. I'll look for a UV sterilizer tomorrow.

Thanks

Plantbrain does it routinely with tanks even bigger than 150 gallons. He uses an ordinary water hose, siphons water out to outdoors on the plantings, then hooks it up to a shower fitting to refill the tank. It doesn't take just a minute, but is less than 30 minutes. Part of the "secret" is having a special PVC pipe setup on the end of the hose to diffuse the incoming water so it doesn't blast the substrate, plants, fish, etc. He has shown us photos of the setup several times.
