i have ordered some digital scales from ebay... now i have to order some ~Bromothymol blue... i see AE have started to sell the solution on its own, without having to buy the whole test kit...

i don't have digital scales for measuring just measuring spoon set... can i approximate with spoon measures and test with a testing kit... sorry about the swear words ... :lol:

cheers for the input.... is it possible to uses biCarb of soda ( baking additive ) and if so at what concentrations....

hi i have just mixed my own 4dkh solution ... i hope ..!!! i used a mixure of De ionised water and my tank water at various concentration to get 4Dkh ... total cost £1.00 my only problem is i have 2 bottle of reAgent and 1 bottle of ph tester... (seem to collect this stuff over the last...

don't worry about that, i have enough surface movement to disrupt any scum build up.. :lol:

the proflora Ph-Controler plus a cheap German solenoid ....

its surprising how little surface movement you can get away with .... aslo if you remember i use a computer controlled solenoid..... i am in my 6 month of a 2kg bottle.... it must be sponsered by Duracell...!!!!

i was dosing a 275l tank.... it really is much cheaper to get a bigger bottle filled....350g=£8.50 2kg = £26.00... i may have had the surface turbulence to high ... it was just after i got into the whole tank thing..!!!!

i have the profi 2000 set up ....which i was able to have refilled at my local fish shop no problem.... i had a 350g bottle supplied but had to upgrade to a 2.5 kg bottle as the 350g bottle lasted only 1 month ... but the regulator still fitted the bigger bottle fine.... so in my experience the...

i think i'll stick to my method of cross referencing as from experience computer foul ups are mostly a result of human error and intervention...(this is why we have them..!!!) controlling of the co2 is regulated this way with inbuilt safety parameters ... a bonus if stories of co2 rapid dumping...

i understand that ph probes measure ph levels, but surly this is used as a guide and if used in conjunction with a calibrated drop checker it will give you a suitable tank rating/ph level based on a 30ppm drop checker reading, so i feel that a +/- 0.05 reading that my probe will control via my...

i wouldn't run the co2 into the filter 24/7, any co2 built up will get released into the tank at night if the co2 is turned off, this will give the filter a chance to expel built up gases...reducing strange noises this is a lot easier to do with a co2 probe, computer and solenoid... if your...

As long as you don't have to much surface turbulence your ph levels wont drop that much overnight, my ph computer reads 7.00 at night and 7.19 in the morning, i then turn on the co2 a couple of hours before the lights come on, gets me back up to speed in no time... as i pump co2 into the...

i don't bother with a defuser at all. i drilled a hole in my intake pipe just above the strainer basket and sealed my co2 line to that,so the co2 runs into my eheim 2026 pro2 filter and then the filter breaks it up... i can also press the plunger down a bit to get more co2 into the tank and this...

£8.50 for a 350g bottle, £26.00 for a 2Kg bottle... still cheaper than the aquatic design center

love this website.. Light the fuse and step back a few feet..!!!! cheers ...

keep me posted on that one.... :D

i used pay 8.50 for a 350g bottle ... didn't even last a month, i'm sure it was only half filled

you get new ones filled and delivered and keep the bottle for £22.00 .... :shock: i wanna piece of that action... :D
