Hey guys... I have had a diatom problem in my 27g Hex and 30 long gallon tank for like 10 years now... Constantly have to wipe the glass.. take ornaments out and let the acid rain outside take care of them... lol and clean everything.. literally every like 2 weeks the glass gets brown..
I know they are diatoms because they wipe off easy and turn into like a powder in the water... I am finally fed up with it.. specially now that both my tanks are heavily planted.... The plants are getting brown algae or diatoms on their leaves and I cant stop it... The leaves on red nesaea and Limnophila hippuroides are too small to wipe off.. My nerite snails ignore them even the horned nerites.. My oto cats ignore them as well..
My plants are actually dying now because they are covered in the stuff.. The new growth is lush and green and orange/red/pink depending on which plant it is but the old grown is coverd in diatoms.. the leaves are small and dying... Its frustrating...
I found out my tap water has phosphates and silicates in it.. I bought a Phosphate test kit and I have 1-2PPM phosphates in the water and I couldn't find a silicate test kit anywhere but the knowledgable lady at petco who run salt water aquariums in her own house said the tap water has silicates in it as well.. I did some research and the lady as well showed me in the store a thing called seachem phosguard.. It removes phosphates and silicates in the tanks water.. She only had 1 pouch left though and it was only for a 30g tank.. I have a new 55G tank as well and it too is getting diatoms all over my pretty plants... So I got that bag she had, and went to petsmart and they sell API Phos Zorb which are pouches as well and remove phosphates and silicates.. I got one for a 55g and a a box with 2 smaller pouches for my other tanks..
It says to put them in high flowing water so I put them behind my HOB filters right before the water goes back into the tank. I was told by a guy on another forum though that plants need phosphates and I will kill my plants using these things and to buy a Reverse osmosis system... but frankly those are $150-250 and I am not spending that much money nore have that much money...
Will my plants be ok with these pouches ? Cant I just use them until my diatoms are gone (assuming that means my silicates are gone) and then take them out and dose some phosphate back in the back tank using seachem flourish or something ? I used to do weekly 50-70% water changes in my tanks before I had my plants because my nitrates always sky rocketed to like 40-80ppm after a week... but now my nitrates are actually dropping to around 10-20 because my plants so I don't need to do water changes like that anymore all I do is top off the water... I understand topping the water off with a few pint's of water will introduce new silicates but it cant be nearly as bad as doing those 50-70% water changes lol
Here is a pic of the diatoms im talking about
