Stay with me, I'm trying to replay to all ya'll
Smite,
what u said before about my cannister filter holding onto unwanted bact with sponges made so much sense! therefore I immediately removed 50% of what I had in there. It also made me pay more attention to cleaning it however, I haven't been cleaning it 1 per wk. Probably twice a month. Should i be placing what little foam i have in any particular way? I assume intake so i did, i wasnt sure if i was supposed to surround biomax so I did. No other foam. I am going to buy some matrix. Obviously lfs is charging lots so I won't wait for them to have bigger pack. Should I place foam in between matrix and carbon bag?
Wc- started with 25 gal like you said For about a month. I've been doing avg 17 gal wc lately once a week. No4 at 7ppm now. I assumed since my no4 was down I didn't need to do 25 *looking back at it all now, the sugar is what dropped my no4. Not wc particularly. And with that I shouldn't have went against your word just cuz no4 was lower. Now I'm getting back to that point. I'm seeing the 25 is necessary for my tank, naturally with what I have (at least without matrix now), cuz of those nutrients, or what not, causing more cyano. And naturally without sugar no4 is probably climbing very slightly again... Got it.
What if I took half my rubble rocks from the tank and just put them in the filter? Would that do anything? I'm thinking not because some bact don't like high flow areas. Correct? That's how I thought the nitrifing bacteria was, so I've been puzzled by that matrix in the cannister...but I will trust that works...
Thank you. Your awesome.
Beanmachine,
From what u just read, I have been playing around with the cannister. It is good for 100 gal. And I do have a hob protien skimmer. It's the tropic marine v2 skim 800 good for 180 gal I believe. I've been trying to pencil it in. after my first chemiclean dose, I was forced to turn pump down. I haven't messed with pump before. I am now getting better more fluffy bubbles. However this morning I noticed it's spitting lots of micro bubbles. I moved my power heads around yesterday and though that look was flying sand. This morning I realized it was micro bubbles from skimmer. So Idk the probs I'll have from that happening. It's still full of micro bubbles. I did use more chemi clean yesterday... other than the changes I made yesterday, if it affected it somehow, is there a particular reason for my micro bubbles today?
Thank you for the explanation of cyano! You should come work at the lfs hahaha I will be purchasing dr tims. I have been referred to it before (cough cough, Jose casa). In terms of needing bacteria when talking about the cyano and watching the bad effects happen in front of my eyes, something you said clicked and now everything everyone has said about "dosing" makes more sense and I thank you.
As much as I love my coral skeleton, I will take it out for now (it's really the bf who wants it there so this will be a rough one) it's not gunna hurt but hopefully do good for now at least. It may be back in there later hehe
Rock- I agree I need some more! Yet again lfs doesn't have any live (lost supplier) and hasn't for the last 3 mths. I managed to get 3 rocks from them. Got an astrina! (Removed) And a brittle star (researched and appears I got an ok one) so that's a step in the right direction I think. I saw questioning of cycling rock, as of now I feel it's a "better be safe than sorry" issue at this point so I'd feel safer to cycle it a bit regardless. As long as I'm not killing goods. I'll use heater and power head. And Tank water?
Thanks
Ndrwater,
I'm just venturing into phosphates. I tested monday at lfs with api so I don't know exact. It was definitely lower than .5 I'd say in between the 0.0ppm and .25 ppm mark. I'm gathering it's supposed to be at 0 or 0.015... so it is high? I looked into rowaphos and I feel that will be on my shopping list as well. That can work in cannister with matrix as well? Or should I do 1 or the other?...
You said "use skimmer but no collection cup" uhhh I'm not looking to swim in my living room, so I'm assuming I'm not sure what you mean haha...
R/O set up and working!! So far I pulled 10 gal yesterday removing cyano. filled with ro and I have about 30 gal now to use for a wc!! Yaaa.
If ya'll come to ohio I want to meet you! Shake your hands
I think BeanMachine nailed it.
If you have your phosphates and nitrates down the bacteria is probably the way to go. If you still have enough chemi-clean left over I do a treatment to kill off most of the cyano. Then add the dr.tims to help out compete what's left.
If your nutrients aren't down yet from the 25g water changes a week then you have an issue most likely the canister like BeanMachine stated. You gotta clean those out once a week if you have any sponge/filter material in there. Stuff gets stuck and rots, not allowing your skimmer to pull it from the water column.
If you really love your rocks order some of that matrix I told you about before and fill your canister with it. Then once a month or so take a 5g bucket of clean saltwater and dump the rocks in. Swish them around to get the detritus out and place them back in the canister.
It sounds like your lfs is priced way high on the matrix. I fill one and a half tlf150 reactors for 10 bucks of the stuff. Works great for pod breeding grounds. It never goes bad or needs replacing. It's just super porous rock broken into small pieces for more surface area for bacterial growth. With water being forced through, like in a canister filter or reactor, you get a decent amount of increased filtration without having a bunch of rock in you DT
Hope that's helps some.
[MENTION=3628]BeanMachine[/MENTION] - you think she'd need to cycle new Marco rock? I thought that stuff was pre washed and n phosphate free?
Sorry if I'm going to repeat something someone else has said...
Anyway to ditch the canister filter? Its probably doing more harm than good. When was the last time you cleaned it out?
Instead of the canister filter, I would get a properly sized hang on the back protein skimmer. I probably missed it but how often do you do water changes? And how much water do you change?
Also, cyanobacteria is extremely efficient and doesn't need very much nitrates and phosphates to reproduce and grow. It can grow in low nutrient systems (low nitrates / low phosphates). Order yourself some bacteria in a bottle, like Dr. Tims. You have a bacterial imbalance and by adding a different bacteria, it will effectively outcompete the cyano for available nutrients.
I would also ditch that coral skeleton, and order yourself some better and more porous dry rock like Marco Rock or BRS Pukani (or live if you have access to it). Not too much (it doesn't have to be a rock wall), but enough to add a bit more surface area for the other bacteria to colonize. If you purchase dry rock, cycle it in a bin of saltwater with a heater and powerhead for a month or so.
I think the probability of the Phosphate coming in your source water is high. Knowing where you truly stand is key. Good test kits are essential. I personally use the Hanna Checker for low range phosphate. Very easy to use and very accurate for it's price point. Running a good quality GFO like Rowaphos will definitely help.
I think you have just reached that point in your tank where nuisance things like Cyano are starting to show up. I agree with several posters that unfortunately the canister filter may not be the best choice for your tank and may be contributing to some of your high nutrient problems. Given a bit if time, GFO, maybe another round of Chemi Clean (make sure the skimmer is running, but no collection cup), and getting your RODI up and running so you are starting with great water for water changes you'll get your issues licked.
You have definitely come a long way from where you were when this thread first started.. Keep the questions and pictures coming..
