Bba?

all of a sudden this showed up in my 75 gallon. looks like little green specks, about the size of a qtip tip. should i remove it or is it a good moss/algae by chance?

Ugh! That looks like what I understand to be BBA! Its a pain and I commiserate with you.

I fight it periodically as well. In my case, I believe it is due to an imbalance between Co2, nutrients, and light. I dont have Co2, so I consistently have to adjust lighting and nutrient levels to find that "sweet spot" of equilibrium given the low-tech environment. I do dose Excel, but I think it helps more to deal with algae ( the effect) than works as a substitute for lack of co2 ( the cause).

But, these are all the "opinions" of a beginner. Im sure someone will swoop in and correct the errors in my assumptions- LOL!

That does look like BBA. If it is just on that rock, you could pull it out and put some H2O2 (hydrogen peroxide) or Excel on it. Can also use Excel to "spot treat" the affected areas in your tank.

Cause is probably too little CO2 (if you are injecting CO2...) or too high of dissolved organics (plant detritus, fish poop, food, etc). Give the tank and filters a good cleaning. Algae hates clean tanks.

For what it's worth, it's a pretty common algae. Welcome to the club!

ok. i pulled the rock, seems to be the easiest solution.
i have no idea where it came from as i haven't added anything in a log time and i keep the tank pretty clean.

can this stuff lay dormant for a length of time and then regenerate?

and is it true that amano will eat this? because i have another tank with several amano whom i guess would appreciate a new snack.

That's my understanding on both questions, yes.

I am a BBA fighting veteran and what I find interesting is how there is so much on that one rock and none on the surrounding ones . OP , is that how it is or did you just take a pic of that one bad rock ? If it is just that one rock , why ? Color of rock , location in tank , etc ? I have noticed in my tanks that the darker an ornament , sponge ,whatever , the more BBA will grow on it as opposed to lighter colored things .

My wife says if I get one more aquarium she is going to leave me . I sure am going to miss her fried chicken .

That would be a surprising find. I've seen BBA grow right on a white ceramic diffuser and of course on glass which is clear. What kind of objects do you have in your tank that are dark and which are light?

In one tank I had a wrecked car that is black and dark greys . I just recently took it out and peroxided it and left it out because it was covered in BBA . It grows on my black prefilter sponges . In my other tank I have a ceramic pipe . Looks like a terracotta one . It is light beige except the female end which is a dark red . BBA grows on the red part but not the beige . It does not grow on HOB intake stems nor heaters , or tank glass . Does grow on my dark driftwood too . Both tanks have BDBS substrate and I have never seen it growing on it , so that is the exception to my theory . I had a small house in one tank that is dark grey and it grew well on it too . Oh , I have Inkbird temp controller probes in both tanks . I have them sealed in black drinking straws and you guessed it , they get a lot on them too . I don't know , maybe I am grasping at straws , no pun intended...lol and need more input from OP , but just curious if it grew on just that one rock of his . BBA seems to be an elusive foe so every bit of info we can gather helps .

I have it rampant in my 60 gallon tank right now as we speak! I thought I heard that Chemi-clean was recommended as well? Or was that a different algae?


Edit: This tank is a discus tank that gets 2 x75% water changes weekly and has immaculate cleaning of substrate and filter- I figure must be the "too little Co2" in my case.

I'm not familiar with chemi-clean, sorry &#x1f615;

My understanding is BBA like a range of 5-15ppm co2. I don't know if that info is up to date or not, though.

Too frequent water changes, plant nutrient imbalance, unhealthy plant mass, detritus and periphyton is where BBA loves to grow. It does not care about flow, light intensity or duration, plant nutrients nor CO2 levels.

BTW, if you donít have Excel or peroxide, dipping infected items in vinegar for few minutes will kill BBA. Dipping plants for 5 seconds will get them clean too. Flush with tons of tap water before returning them back.

Thanks @Edward. I do have Excel and peroxide; so, ill do what you recommend.

The too frequent water changes I cant do anything about- its necessary for the fish-stock. So imagine it will be a problem I will continue to struggle with.

Could you expand on this a bit? It's the first time I've heard of some of those specific reasons. To give some perspective, I've definitely come from the Tom Barr/barrreport school of thought on everything.

"Too frequent water changes" definitely seems counter intuitive

So does it care about plant nutrients or not

BBA is not tied directly to plant nutrient imbalance or unhealthy plant mass. It grows in fish only tanks as well. Just take a look at your LFS. The common denominator that a fish only tank and a planted tank has is organic waste. To much of this for the system and BBA will eventually grow. Duration and light intensity will make it grow quicker just like most plants. Co2 will help only if the plant mass is there for plants to increase uptake in the system to remove waste from the decomposing organics.

BBA is one of the most common algaes to get, but its also one of the most straight forward ones to remove.
