heather Posted August 22, 2005 Report Share Posted August 22, 2005 Have you got Sera Start with the fizzy tablets or the money version with the gas bottle etc? Quote Link to comment Share on other sites More sharing options...

heather Posted August 22, 2005 Report Share Posted August 22, 2005 Ive had Sera Start in my 250L for 2-3 months now and its working ok. It's easier than mucking around with yeast which i did try but decided thats it just too cold in Taupo for it to work well. My lfs mainly stocks Sera products and he was using it in a 200L at home and recommended it to me. My plants have definately taken off but my main reason for putting it in was to stabilise the pH as the water is very soft, Kh2. I presume you also bought the CO2 test kit. My lfs recommended to put 3 drops of tester in as the colour is easier to read and i have found this to be true. There are two things about it that i would change if i could: 1, the tablet holder needs to be in the flow of returning water so it ideally needs to be placed along the back wall which is difficult to get to when there is a canopy invloved. 2, the amount of gas lost through the holes in the bottom is a little bit annoying but more frustrating is the amount of gas lost because the container can't hold it all. I could let out the remaining gas before i put in a new tablet but i would have to completly remove the canopy to do that. The other way is to break a tablet up and only put in half and if it looks like that is all that will fit i do do that. It would be better if the container were bigger. Overall though, i like it.

LYNDYLOO Posted August 22, 2005 Author Report Share Posted August 22, 2005 Are you also using the fertiliser tablets that come in the pack? I have got this running in a 330L tank, not sure if it's gonna be enough to feed the plants, may have to run me old yeast set-up aswell. Whats this test you are talking about, does it test how much CO2 in ya tank, no-ones told me about that, didn't know it was available.

heather Posted August 22, 2005 Report Share Posted August 22, 2005 When i bought the kit it came with the tablet/gas holder and a packet of tablets. I bought the tester separately but on the same day. I didnt buy the version that came with fertiliser cause already had some and besides my substrate is sand and aquatic potting mix and so far haven't found the need to use fertiliser yet. The CO2 test kit came in a box that looked the same as all the other Sera test kits. Its a small plastic two part container that gets suctioned onto the inside of the tank a few inches below the waterline with some reagent in it. Included was a three coloured sticker for the outside of the tank for comparison. If the reagent is light green dont add a tablet, if its blue then do and if its dark green its just right.

LYNDYLOO Posted August 22, 2005 Author Report Share Posted August 22, 2005 It sounds abit like the ph test kits , the guy at the petshop never mentioned that you could even get something like that, have ordered another CO2 test kit, as I wasn't aware that you could even get one,so hopefully that will work the same way. Thanks for the info. Lynda :roll: Quote Link to comment Share on other sites More sharing options...
