<p><br/> In the event that you need to bond to the masonry with conventional mortar or grout after application of paraffin wax, it will be necessary to remove the wax. The wax needs to be vaporized. This could be done at lower temperatures in a lab with application of low pressure (vacuum). In an outdoor setting the best method may be to build a charcoal fire and slowly increase the oxygen supply from a metal pipe and a blower or compressor after the interior of the tank exceeds the melting point of the paraffin on all surfaces. Apply heat until no more smoke/vapor is being released. Allow to cool slowly without any water. Masonry can tolerate heat to 300C (572F) without damage and 500C (932F) before destruction is likely. Paraffin wax boils/vaporizes at 370C (698F). I suspect you will get ignition at much lower temperatures than that so basically, burn it out and limit the oxygen to keep the temperature down.</p>

<p>Just remember, once you paint with epoxy or seal with paraffin you have placed a substance on the tank that will not readily adherer to more mortar or Thoroseal. I had no problems and did nothing more than rinse. I suggest rinsing and following the directions from Thoroseal. Then test the water and determine if further action is required before committing to a second layer.</p>

<p>Bob Campbell, I painted with swimming pool epoxy paint. The ph is 6.8 the salt level is 38.</p>
<p>So everything came out perfect for my fruit trees and fish. With the last rain the tank is full till it overflowed.</p>
<p>That's 70 cu meters= 2475 cu.ft. of clean rainwater. My only problem right now is some birds eating my fish. Thanks to all for the help.</p>

<p>Jon & Bob, the irrigation water I need should be 6,5 for the tropical fruit trees I grow. I build this tank as I allready have two wells with brackish (3700 micro siemens) and high ph water which affects the trees and the clay soil (iron chlorosis).</p>
<p>That's why I am asking if the epoxy paint will isolate the high ph cement. The tank is to big (65 cu.m) to be rinsed.</p>

<p>I agree with Jon Parr. Too much is being made of high pH. I've built concrete tanks and placed Koi in after a couple rinsings without any problem. Eventually the concrete will not affect the pH at all.</p>

John S. If you're just using your tank for tilapia and irrigation, don't worry about pH. Get it a good scrub with saltwater when you're done with cement, and let it fill. Tilapia and algae enjoy high pH, and the soil will buffer it anyway when used for irrigation.

<p>I have similar problems like Josiah. I have just finished this watertank, diameter 5,2 m en 3.20 m deep.</p>
<p>It will be used to keep tilapia and harvesting rainwater for irrigation. My problem is the separation of the cement walls from the rainwater to not affect the ph of the rainwater.</p>
<p>If I were to follow the advice of Ian Cameron to paint with epoxy, what problems could arise, besides the fact that cement will not adhere to the epoxy paint?</p>

<p>If you have any problems later with the PH or it starts leaking you can try using a epdm pond liner with a geo textile underlayment. </p>

<p>Hi John,</p>
<p></p>
<p>I'm just now seeing your message... Yes the pH seem to be right now, about 6.5. I hopefully will get fish soon!</p>

<p>Thanks for checking on me,</p>
