Problem with sponge filters

Recommended Posts

neo-2FX

I'm wondering any other SKF folk are running into the same issue as I with Biospon filters.

I'm finding that they're losing their suction/output and even after taking them out, squeezing the sponges, re-connecting everything they'll run at full output for only a couple of months before having to repeat the process.

I'm trying to determine whether it's the airline tubing coming loose or just the filter connections.

I've got a few ideas about fixing it permanently like sealing the connections etc. but just wanted to know if anyone else has run into similar problems?

I have been giving mine a rinse/squeeze at every second water change and haven't had any issues yet. 

I've just bought 2 new ones and looked at the weighted bottoms and thought let me open it up and have a look whats in there. To my surprise it's looks like mild-steel discs and not even sealed well. This is a definitely rust issue waiting to happen. 

Have you noticed anything like that with yours. 

I would have posted a picture of it but I can't shrink the size of the photos on my phone.

I'm always hesistant in removing them often because

a) could lose some baby shrimp on them when putting them in a bucket

b) may disturb the tank too much and stress shrimp

What filter media do you have in your one that's running?

I have Seachem Matrix in all of mine so I wonder whether they're somehow clogging up the chamber easily.

I haven't noticed that actually. Please post up a photo when you get a chance, you've got me interested in that and will pay attention next clean.

I am using Seachem matrix carbon. 

Unless I can figure out how to shrink photos on my phone I don't think I would be able to post a pic. 

Will have a look today. (Dam iPhones)

So far I have noticed two issues with them.

1. Suction cups loose suction and not sticking on glass after some time even though the suction cups still feel pliable, unlike some of the cheap suction cups that 'hardens' after being submerged in water for some time. I don't have a solution for this. Currently, I let the filters 'sit' on the substrate.

2. Losing their 'output' like what you have described above. The part that clogs up is at the joint between the transparent tube and the grey bit. If you pull out the tube and look inside the grey bit, you will see little holes that allow air to pass through. Give those holes a brush and output should resume. Another way without getting your hands wet is to use a syringe and forcefully purge air through the airline a few times and it will purge the gunk out. The output should resume after the 'purge'.

Hope this helps.

This information is golden, thankyou! I had a suspicion it was that area because I would sometimes see air bubbles coming from there.

I too have the same problem you mention in point #1 but a quick push against the glass re-attaches it.

I'll give the syringe method a try tonight and report back.

@jc12 you sir are a LEGEND!

The syringe trick worked perfectly on all three of my tanks!!!!

Thankyou so much!

I can sleep well tonight

Not quite sure which part you flushed out. Can you show a pic of the general area?

I'm guessing it's the inside of this part circled.

There must be small holes, like @jc12 described, on the inside where the air comes down the airline and into it.

Ok, that makes sense now with a picture. Thanks.

Bingo @neo-2FX. It is exactly what you have circled in the pic above. Glad to know my very detailed description was effective. ?

@jayc, seriously mate you need to pay attention and follow closely what I said. The transparent bit and the grey bit. How did that not make sense? ?

Grammer. A bit slow today like @jayc. ;P

LOL. I'm a bit slow today.

In my defence, there are transparent bits and grey bits all over the Biospon.

      In case it helps I have looked up the figures of the 2 tanks with cherry shrimp in them and they are as follows, Main tank     PH7,, GH5, KH2, TDS 225 (mixed water) Betta tank  PH7.5, GH6, KH3, TDS 222 (tap water + mineraliser) They are fairly similar to each other but neither is really in the 'IDEAL' recommendation range of CHERRY shrimp ,so it confirms that cherry shrimp are more adaptable and can thrive even outside those 'IDEAL' parameters? I suppose neither are that far out but it just shows there is a bit less necessity to get everything 100%, though if you aim for perfect you will probably get better results all round? Simon

      Oh, if you are planning on keeping Cherry shrimp aim for 6-8GH as Simon said above.
    • sdlTBfanUK
      Do you know what the water parameters are of this tank? Is the new male old enough to breed, assume it is as they only need to be 3 months I think but is that a possibility? Simon
    • sdlTBfanUK
      The usual GH range for Cherry shrimp is 6-8 and with the 1 part tap, 3 parts RO water mix you will be 50% there for G|H and just under 4 for KH! There are 2 products, one is GH+ and one is GH/KH+ so you need to get the right one for whichever route you plan to go, all RO water would be GH/KH+, mixed water would be GH+! IF you are planning the mixed route then that would be an easy adjustment you can do now by taking 25% water out and replacing with dechlorinated tap water, then adjust with the GH+ when you get it? This is the one I use, it is so simple as it is a liquid and even calculating is easy as each drop = +1gh (about 20ish TDS) / litre: https://www.pro-shrimp.co.uk/shrimp-king/803-shrimp-king-mineral-fluid-double-gh-4001615061413.html If you want to get this I have just done a dummy test on the website and you get delivery on it as long as it is one item, which is normal, but I thought you may need to pay as it is a bulky item to send? The soil should have lots of what the plants need I would have thought and the poop from the snails/shrimp must be some fertiliser? As JayC says you could leave the CO2 running for now as there are no shrimps, but I would probably turn it off and stop using fertiliser and just keep a close eye on the plants at this stage, after all you can start using them again IF the plants start looking unhealthy, but neither may be needed and it is better to know from the start and will make life easier long term. As I say I have never used either and my plants grow fantastic, in fact I wish they would grow slower, doh! Simon

      Ahhh ... the age old question of how to trigger your shrimp to breed. We will have to assume you have at least 1 male. What are you feeding them? Feed frozen bloodworms twice a week. The additional protein will give them more energy. Add more Indian Almond Leaves (aka Cattapa leaves) to the tank to promote more tannins and biofilm. Try raising temps to 23C or 74F. A 10% water change might help the females moult.
