Drip line method for water changes and/or top ups


Sprae

Recommended Posts

Here's a very simple 10-steps drip lining method I use every time there's substantial amount of water (300ml or more) added to my nano tank

  1. Get any long airline tubing and an empty clean plastic water bottle
  2. Make a hole on the plastic cap just big enough to fit the tubing tightly (use a big nail or small knife).
  3. Push one end opening pass the cap hole and tie a loose knot before the cap
  4. Place new water container near tank, preferably water level is above tank level
  5. Put the tubing into the new water and the knotted cap end screwed close onto the bottle
  6. Lower the bottle below container and compress the bottle and expand it, until the bottle starts to suck/pull water into the bottle
  7. Once you have a water flow, tighten the knot until you get a slow but consistent drip (2-3 drops per second)
  8. Unscrew and place the dripping line in place for topping up.
  9. Loosen or tighten knot to manage the drip rate over the duration to your preference.
  10. Remove it when tank water level is where you want it.

Open for feedback and different ideas from the experts. Hope that helps :)

Good write up!

Constructive feedback;

Pictures would be awesome, It just helps people to visualize what they're reading.

Also rather than tying a knot in the hose I find flow control valves to be easier to control the water drip flow.

A peg also works well to keep the airline intake tube in the fish tank without slipping out.

And a cheap soldering iron works well to melt small holes in plastic, This works well for DIY co2 also.

Great work on the write up.

Being a drip feed there is NO need for declaration, as there is never enough new water at any one time to be a problem.

A constant no messing around way to do it is to set up a pressure reducer on a near by tap and use 25m PVC and fittings, all glued together and you can use stop cocks to slow the main line flow and there is screw in drippers that you can screw into a 25 x25 slip joint T piece that has a reduced 13mm thread to adapt the dripper to. 25mm is the best to use as it acts like a reserve so there is even preasure all over.

Sorry i never took photos of it, if you are worried you can put the drippers on a irrigation timer so you have total control.

Yep I have built lots of different systems, maybe there is one in a LFS near you.

If ever you set up a fish room air system, please use a 40mm waste pipe, it seams like an over kill, but there is even pressure all the way around and you air pump will work WAY better.

I use gravity and a small flow control valve like this [ATTACH]793[/ATTACH]

Or this

But now I just got this little baby and set it up

Very simple float valve works with gravity feed or RO unit.

The only thing that worries me with float valves is when they decide to stick

I use a 2L Sudo box. Nice slow drip and leave them be for 24-48 hours. Make sure the WP are the same as the tank, and then remove the small grill that stops them escaping and they leave when they want.

I have also used a very similar drip method in the past or when my Sudo is in use.

The one thing I failed to mention is, you need to put over flows in the tank as it is a water change system, not a top up one.

Fox where did you get the small float valves from? I have not seen them for years

Wow guys! Thanks for the all different ideas. :encouragement:

I'm interested in the small float valve too. Nice idea for auto-top system.

I purchased a very similar float valve for my ATO in the shed from ebay for about 6 bucks.

Edit: they are as far as I can see identical

nice post! yeah trav i use the sudo box system too. very very easy and you can monitor the shrimp the whole time

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
