It's not you mate that is a very poor explanation, lolit may be glaringly obvious, but i just cant quite make out what this means exactly? the EI bit is confusing me......you dont mean Estimative Index here do you?.....is it a typo or abbreviation for something else....or am i being dumb
What I should have said is this "I'm seeking an alternative to Estimative Index when I scape the 200ltr tank as the position of the tank would make lots of water changes a nightmare"
EI is what I'm doing for the Black Lava Rock scape.
I apologise for making you question your intellect, when indeed it was my fault for writing anything on a public site before having my morning coffee.
I should know better, lol.
