so should i go for co2 with my tank set up? if so what should i get because ive seen pressurised units refillable and disspossableso is there any difference in the two? and how long would a 600grm bottle last me roughly in my 125ltr tank?
also ive been in talks with 'Plants alive' who worked out how many plants i need which they quoted
"25 or 50 Hemianthus. It is a very small plant and needs quite a bit of patience to split it up and then plant it in a hatched pattern to allow it to spread.
25 Sagittaria Subulata and 15 Echinodorus Amazonicus.
Cost would be £30.20 including P&P if you go for 25 Hemianthus or £39.15 if you go for 50 Hemianthus"
does this sound about right?
