PH keeps increasing..

Recommended Posts

DG17

Hi guys,

as some of you may know I have a shrimp rack consisting of 2 3x1.5x1.5 ft (divided into 3each) tanks and a 2x1x1.5 ft sump..

I cannot work out why my ph keeps increasing as I'm running 8cm of bennibachi soil and nothing other than a small oxydator, 2 mineral balls and clay caves from dean.. Each tank has plants and moss in it..

All I can assume is that it's my media in my sump increasing ph, I'm using eheim substrate pro and ceramic rings and of coarse sponge and wool oh and a bag of Purigen..

My EC is 210

GH 5

KH 0

PH has crept up to 6.5-6.7

Tank has only been going for about 6-7months and when doing 10% water changes I use RO/DI water with salty shrimp to the total of EC 100-120 so soil shouldn't be exhausted as yet..

tested RO/DI water and its fine..

Do you think it could be the eheim substrate pro or ceramic rings.. Should I change one or the other and if so to what, matrix maybe?

Thanks

Hey mate, im reading conflicting reports on other forums after a quick google, there was one good suggestion though- conduct an experiement!

Set up a couple of glasses with water in them, have one with just water as a control, one with some of your ceramic rings and one with the substrate, test the ph's over a period of time and see if any of those seem to affect it.

It shouldn't be exhausted yet but you never know, I suggest getting some Fulvic grains from Dean & seeing if that helps. The grains are what buffs the PH in the Benibachi soil so adding more should help. :encouragement:

I think I'm going to have to do that.. Ill make up 3 glasses with the tank water and see how it is in a week.. Thanks mate..

the ph increase is caused by one or the other it's doing my head in working it out.. Haha

thanks champ. Ill set it all up tomorrow and get back to you all with results

thanks sqigs

ive already got 3 packets off our good man dean, I just don't want to use it as yet and find the problem.. Anyone using eheim substrate pro or matrix and noticed a problem with PH at all??

I'm using both Matrix & cintered glass noodles & I have a stable PH of 5.5 :victorious:

Are the two PH readings taken during the same time of day ?

I've been told matrix effects KH.. Obviously not true in your case.. :)

Hey bb, yep they are.. It drops a tad a night but only by .1 or so.. I have a ph controller running to see it more accurately it's even a new ph probe, the glass dupla ones.

what media do you use BB? I'm pumping substrate pro, I can't find info anywhere saying increases ph in the net.

It's been a while since we heard from you DG17. After reading your thread I decided to test my ph for the first time in 6 months. The solution turn yellow which indicate ph 6 or lower. I use eheim substrate pro, eheim noodles, and another eheim media that I forgot the name. Did you test the tap water with your ph tester, it should read around 7.4 ish. I do this to know my ph tester is collaborated

Hey mr shrimp, yep I know, these days im jumping on a couple of times a day sneaking a look while I train some of my boring clients haha.

Ok it might be my ceramic noodles/rings. I have 2 ph test kits one new and one almost finished and a dupla ph controller and just calibrated the probe and all read the same.. I'm stumped, going to do my little cup test this week and see what happens in a week.. But I'm glad someone else is using substrate pro without probs..

I have heard some of the ceramic ring from cheap company do raise Kh/ph. That's why I invest in ehiem media. From memory, I think Dean also uses ehiem substrate pro.

Trust the only thing that's cheap in my set up to give me grief haha.. Well I bought 4 more boxes of substrat pro but want to change them slowly!

fingers crossed!!

what media do you use BB?

I'm a eheim fan...so all my canisters, media (noodles, substrate pro...etc) are eheim branded .... I'm a brand tragic ! LOL

Well in that case it's safe to say I'm sticking with eheim!! Haha

well I've set up 4 cups 1 with just water from my tank and no media and the other 3 have water with matrix, substrat pro and ceramic noodles.

At the moment all 3 cups are 6.3 ill test again in the morning then again in 1wk.

Time to post my results with ph increase test on media.

cup 1. Normal tap water ph 7.4 one week later still 7.4

cup 2. Eiheim subtrate pro and tap water 7.4 and stayed 7.4.

cup 3. Cheap crappy ceramic noodles woth tap water ph 7.4 increased to 7.5 (not much I know but still an increase)

cup 4. Tap water with benibachi soil ph 7.4 a week later drop to 6.8 ( prob would drop more if I put more than a few mm later but good to know my water is still doing its job.

i used my digital dupla ph controller to do the test.

I've set up another cup to see how long IAL takes to start bringing ph down.. So I put a fresh leaf in a cup with tap water lets see what happens.

Great results dude, very interesting to know that the stuff in you tank is mostly decreasing the PH, so I wonder what is causing you increase? Hmmmmmm :confused:

What is your moss on? Any on rocks? Only need one small rock of the wrong type to affect ph?

      Great to hear everything is going nicely and you feel ready to start transferring more to the new tank. You were always going to have the PH difference as you are using soil but my cherry shrimp I have in both tanks thrive ok, it just means that you should drip acclimate them probably most of the day to be on the safe side and it is easy enough with the dripper to just leave it going all day. I am not advocating doing this, but as I was putting the cull shrimps into the new betta tank which had a low PH due to new substrate I just dumped them straight in and they were fine and I didn't see a dead one ever (I saw 10 the other day which is about the number I DUMPED in there) - they are much hardier/adaptable than the bee shrimps. I would do as you want/propose and try 10 for the first transfer! I really don't think you will have a problem with the PH difference but would do a long acclimatising to be safe. I have the same floating weed and mine grows really quickly but it is much easier to keep that under control than duckweed as when you get too many big ones you just remove a few. Incidentally when I do my weekly maintenance I trim off the longer bits of root to about 2 inches and it doesn't seem to harm them! You should probably keep a close eye on the tanks this week as we are supposed to be over 30 degrees most of the week. The smaller tank will be the one most at risk of excessive heat? I wish my reset shrimp tank was as lush and green as your new one - good job! I have added 17 shrimps so far and saw 8 yesterday? Simon

      Right so i've left the tanks and inhabitants for well this long simply because i dont want things to die off if i can help it and people have said leave it a month after establishing a tank before adding shrimp. Other than doing normal maintenance and transferring the 2 liters of old water from the small tank to the large each time and the large tank then getting an extra 2 liters of mineralised new water. Friday i sorted out all the tank decor in both tanks and adjusted the tank TDS to within 5TDS of each other. mainly because i needed to cull the flaoting plants which in the large tank the frogbit has taken over and in the small tank the water lettuce had almost taken over. the Duckweed has all but died out in both tanks not that i have done anything to aid it. my tanks now look like the attached. i then took readings they are as follows:-

      Small tank
      TDS - 232
      Temp - 23C
      PH - 7
      NH4 - Unreadable
      N03 - 1PPM
      N02 - 0.05PPM
      P04 - 2PPM
      dKH - 2
      dGH - 6

      Large Tank
      TDS - 237
      Temp - 24C
      PH - 5.5
      NH4 - Unreadable
      N03 - Unreadable
      N02 - Unreadable
      P04 - 1PPM
      dKH - 1
      dGH - 5

      So the Phosphate is up but thats because i was massively invasive in the tanks and churned up the fertaliser i have in the tank substrate. The PH is also what i would consider to be completely off

      also as a side note its worth mentioning that stressing plays out seems to stimulate them to give birth, i now have an extra at least 3 fry appear in the tank just after the works when the mothers had seemed to have stopped giving birth.

      i also got a new fish the in other breed of platy because the fish keeper at my LFS told me they could interbreed and it might make what im doing with the fish go faster, i got him today and named him Rodney and am about to add him to the Large Tank with Tyrone  before taking Tyrone out and putting more females in the tank with Rodney to let nature take its course. the Fish keeper did tell me to drip acclimate him however as the PH shock may be too much so that's what I'm currently doing and he's on his 2nd dip.

      that does make me wonder however can i now add shrimp to the tank or is the PH going to be a massive problem. i estimate i have between 60 and 100 shrimp in the small tank and want to transfer over say 10?

      Thanks for replying. I know what you mean about breeding, I started off with about 10 and was soon (couple of months) over 100, and  I am sure that would have kept going up if the tank could  have supported more??? I don't see any reason that it wouldn't work with bee shrimps if it is working so well for your cherry shrimp. Obviously the parameters are different but if you are managing to keep the cherry tanks stable I don't see why the bee would be any different, although they are a lot harder to keep! Worth a try though unless someone says otherwise? I shall certainly follow this with some interest. Simon

      Hi Simon, NO, I wasn't using a buffering substrate previously in the neo tanks, it was just some white gravel that I had laying around. It had originally been in a fish tank some years ago, so it wasn't new when I put it into the neo tank. It started to break down just because of age, and my GH, and subsequently TDS, were rising out of control. JayC talked me through a rebuild with a bare floor. It has worked so well that when I set up more neo tanks I just made them bare as well. Like I said, I wouldn't go back. The little buggers are breeding like crazy, I have a very high baby survival rate and almost no deaths. Under my particular water conditions, it works great ... for neo caridinas. Now I want to do the same with caridinas, but not sure if there's more to a buffering substrate that I don't know about. Hopefully someone out there will be able to help me (and you) with the answers :)
